INTRODUCTION
This booklet describes the diagnostic pages and
codes that can be shown by the Rockwell Collins
avionics system. This publication is intended to
help the flight line technician use these built-in
diagnostics to test and troubleshoot the avionics
units.
QUICK TEST:
•
Show the CURRENT FAULTS page and
look for fault messages. If no faults are
displayed, the LRUs are operating
normally. Refer to CURRENT FAULTS
page.
•
Show
the
CURRENT
SERVICE
MESSAGES page and look for service
messages. If no service messages are
displayed, none of the monitored LRUs
require service. Refer to CURRENT
MESSAGES page.
FCS DIAGNOSTICS:
•
Use the FCS DIAGNOSTICS to isolate an
autopilot or yaw damper engage/
disengage problem. The Report Mode
codes identify what is currently preventing
the AP or YD engage and what caused
the last disengage. Refer to the Report
Mode
pages.
MDC DIAGNOSTICS
Enter MDC Diagnostics:
1. Apply power to all avionics systems. Wait 5
minutes so the system can stabilize.
2. Locate the MAINT switch (MFD1/OFF/MFD2)
behind the pilots seat.
3. Set this switch to the MFD1 (or MFD2)
position.
4. Push the UPR MENU button on the CCP. The
STATUS MENU shows several options that
include FCS DIAGNOSTICS and MDC
MAINTENANCE.
5. Turn the MENU DATA knob, on the CCP, to
highlight the MDC MAINTENANCE line. Push
the MENU PUSH SELECT button.
6. The MAINTENANCE MAIN MENU page
shows on the MFD. Push the joystick (on the
CCP) up or down to move the cursor (>) to the
desired CURRENT FAULTS, CURRENT
SERVICE MESSAGES, AIRCRAFT HISTORY,
SYSTEM PARAMETERS, ATA INDEX, LRU
INDEX/OPERATIONS,
MDC
SETUP,
CONFIGURATION
DATA,
REPORT
DOWNLOAD, or PILOT DOWNLOAD TO
DISK line.

5
CURRENT FAULTS Page
1. Show the MAINTENANCE MAIN MENU page.
2. Move cursor to CURRENT FAULTS line and
push the MENU PUSH SELECT button.
NO FAULTS means all monitored units are OK.
6
This page lists each currently non-functioning LRU
that is monitored by diagnostics. A FAULT
MESSAGE line describes the detected problem
(or information) for that LRU. The STATUS column
indicates the required action.
•
FAILED - Replace this LRU.
•
OFF/NO OUTPUT - Check power to LRU.
•
OVERHEAT - Check fan/cooling system.
•
LRU OK/INFO - No fault, information only.
NOTE:
Other information may also show on
this page.
The CURRENT FAULTS page is useful as a quick
system test. It is used to verify proper system
operation after a maintenance action is completed.
Remember to allow the system to stabilize for at
least 5 minutes before using the diagnostics.
Check the CURRENT FAULTS page when a
problem is first suspected. If the diagnostics do not
detect any failures and no messages exist, then
NO FAULTS annunciates. If the diagnostic system
has detected a failure, this page shows the
problem LRU name with a descriptive FAULT
MESSAGE and STATUS condition. Check these
displays and do the required action as defined in
previous paragraph.
7
The CURRENT FAULTS page is an active display
that automatically updates as fault conditions
appear or clear. Most fault entries show on this
page between 0 and 30 seconds after they are
first detected. Some monitors provide a time delay
to prevent unnecessary display of transient
conditions.
If multiple pages exist, move the joystick on the
CCP to the left or right to show the previous or
next diagnostic page. Push the ZOOM- button on
the CCP to show the next higher level page (e.g.,
the MAINTENANCE MAIN MENU page).
8
ADVANCED DIAGNOSTICS Page
1. Select an LRU field on the CURRENT
FAULTS, FAULT HISTORY, or FLIGHT LEG
DETAIL pages to show the ADVANCED
DIAGNOSTICS page.
2. Push the MENU PUSH SELECT button to
show the ADVANCED DIAGNOSTICS page.
9
The ADVANCED DIAGNOSTICS page has the
plain English description of the fault messages.
The top portion of the display shows the reporting
LRU information.
The VIEW DETAILED DIAGNOSTICS DATA line is
used to show the DETAILED DIAGNOSTIC DATA
page. This page shows the data that caused the
fault message or diagnostic words from the LRU.
The lower portion of the display shows the fault
message and the plain English description of the
fault and troubleshooting tips.
10
DETAILED DIAGNOSTIC DATA Page
1. On the ADVANCED DIAGNOSTICS page,
select the VIEW DETAILED DIAGNOSTIC
DATA line.
2. Push the MENU PUSH SELECT button to
show the DETAILED DIAGNOSTIC DATA
page.
11
This page lists the diagnostic words for the
selected LRU. The top portion of the display lists
the reporting LRU along with a fault message and
the display format selection lines. The lower
portion shows the diagnostic word fields and
associated diagnostic data.
If a fault message is gone after a REFRESH
command, MESSAGE NO LONGER ACTIVE
shows at the bottom of the page.
The DETAILED DIAGNOSTICS DATA page shows
data words and status conditions, as well as the
diagnostic words that caused the fault message to
be recorded. The diagnostic words can be from
other LRUs.
Use the DATA FORMAT line to show data in either
binary or hexadecimal format. In the binary format,
the diagnostic words show the word label and then
bits 31 thru 9. The hexadecimal format shows the
word label, the source LRU NAME, and the sixdigit DATA columns.
Move the cursor to select DATA FROM LRU. Push
the MENU PUSH SELECT button to show the
DATA FROM LRU field.
The DATA FROM LRU fields show the octal label
and diagnostic word received from that LRU. A
maximum of ten diagnostic words can be shown.
The field shows dash lines if the associated word
is not received. Each diagnostic word contains
useful information that can simplify troubleshooting
effort.
Push the MENU PUSH SELECT button to toggle
between the DATA VIEW and the DATA FROM
LRU fields.
The DATA USED FOR FAULT display shows all
the diagnostic words that were used in the MDC
12
logic equation.
Refer to the Diagnostic Word Bit Definitions tables,
on the pages that follow, to decode the information
contained in these bits of the diagnostic word.
A Sign Status Matrix (SSM) indication of failure
warning does not necessarily mean a bad unit, but
can mean that a bit is set in the diagnostic word.
Push the TAB button (ZOOM+) to toggle the
cursor between the selection lines of the display
and the diagnostic words.
When the cursor is on the diagnostic word field,
push the MENU PUSH SELECT button to access
the DATA READER page. The DATA READER
page shows the bit state and the definition for
each bit in the applicable label.
Push the RETURN (ZOOM-) button to show the
next higher level page (e.g., the CURRENT
FAULTS page). Push the orient button to return to
the main menu.
13
DATA READER Page
The selection of a diagnostic word label on the
ADVANCED DIAGNOSTICS page causes the
DATA READER page to show. The DATA
READER page contains more information about
the diagnostic word bits. The top line shows the
diagnostic word label and the LRU name. The
condition of each bit is shown on this page (1, 0,
or a dash if there is no data received). The DATA
READER page contains one-line descriptions
about each bit for the applicable label.

225
FCS DIAGNOSTICS Pages
1. The FCS DIAGNOSTICS pages provide a
means to isolate faults within the flight control
system. Use these diagnostics if an autopilot
or flight director problem is suspected.
2. The FCS DIAGNOSTICS are controlled by the
Flight
Control
Computers.
The
FCS
DIAGNOSTICS consist of three basic modes:
•
The REPORT MODE shows selected internal
FCS monitor information.
•
The INPUT MODE shows selected inputs to
the FCC Flight Control Computers.
•
The OUTPUT MODE shows and controls
selected outputs from the FCC Flight Control
Computers.
The left, right, or both FCC computers can be put
into diagnostic mode. On the FCP, simultaneously
push any two mode buttons and the left (or right)
FD button to put the left (or right) FCC into
diagnostic mode; FCC TEST annunciates on the
left (or right) PFD. The FCC that is in diagnostic
mode outputs the MFD display. When both FCCs
are in diagnostic mode, push the XFR button (on
the FCP) to select which FCC outputs the display
data to the MFD. A blue arrow on the diagnostic
page points to the FCC (left or right) that outputs
the display data.
226
NOTE:
The FCCs do not store the diagnostic
codes in nonvolatile memory. The FCCs
begin recording data at power up and
retain this data only while power
remains on. When the airplane is
powered down, all accumulated data is
lost. When investigating an FCC
problem, write down all nonzero
REPAIR, AP ENG, AP DIS, YD ENG,
YD DIS, and STEER codes before
power shutdown. Record all six digits of
each nonzero code.
Certain FCC diagnostic codes are sent to the
MDC computer and can be stored in the MDC
nonvolatile fault memory. The FCC outputs the
REPAIR, AP DIS, AP ENG, YD DIS, YD ENG, and
BOOST code fault data to the MDC. These codes
show in the Report Mode.
If the MDC fault memory is not full when FCC
codes are sent, this data is recorded in memory.
The information is now retained after power down.
The information shows on the AIRCRAFT
HISTORY page as FCC (071 and 351) diagnostic
words. If the MDC fault memory is full when the
FCC codes are sent, the data is not stored.
The Challenger 605 has four FCCs. One pair of
FCCs is active while the other pair is in standby
mode. Turn the AFCS SEL knob to select FCS
system 1 (FCC pair in IAPS quadrants 1A or 2A)
or system 2 (FCC pair in IAPS quadrants 1B or
2B). The CURRENT FAULTS page shows the
diagnostic words from the active pair of FCCs.
Turn the AFCS SEL knob to view the diagnostic
words from the other pairs of FCCs.
227
How to Enter FCS DIAGNOSTICS
1. Push the UPR MENU button on the Cursor
Control Panel (CCP) to show the most
recently displayed STATUS page.
2. If the FCS DIAGNOSTICS page does not
show, push the UPR MENU button on the
CCP.
3. The STATUS MENU shows. Turn the MENU
DATA knob on the CCP to highlight the FCS
DIAGNOSTICS line.
4. Push the UPR MENU button or wait a few
seconds to remove the STATUS MENU.
The REPORT MODE shows on the FCS
DIAGNOSTICS page. Simultaneously push two
mode buttons on the FCP to change the display to
the INPUT MODE, OUTPUT MODE, and then
back to the REPORT MODE display.
A blue arrow on the FCS DIAGNOSTICS page
points to the left or right FCC that controls the
MFD display. Push and hold the XFR button to
change the FCC source of display data.
How to exit FCS DIAGNOSTICS
1. On the FCP, push and hold any three mode
buttons until the FCC TEST annunciation (on
the PFD) goes out on the selected side.
2. Select a navigation display to exit FCS
DIAGNOSTICS.
228
229
REPORT MODE Page
1. Show the MAINTENANCE MAIN MENU page.
2. Move cursor to the FCS DIAGNOSTICS line.
3. Push the MENU PUSH SELECT button on the
CCP.
4. The MFD shows instructions to access and
enter FCS diagnostics.
This page reports the status of internal monitors in
the FCC computers. Five selectable parameters
show LEFT FCS and RIGHT FCS data. Use the
FCP mode switch buttons to select the report
mode operations. Push an FD button to show a
summary explanation of left or right code on
cursored line. Use the VS/pitch wheel to slew
parameters on the cursored line.
230
NOTE:
Record
all
non-zero
before power shutdown.
codes
A Report Mode Parameter list is provided that
gives each parameter available for display.
Parameter names that denote errors show the
total number of errors that have occurred since
power-up. Parameters that denote codes are
given below.
231
If any code is nonzero, push the FD left button to
show a left summary screen to interpret that code.
The FD right button can be pushed to show the
right summary screen to also interpret that code.
The summary screens are dynamic displays that
show code explanations in order of priority. The
top line is the highest priority.
If there is more than one problem, solve the
highest priority first: related problems may also go
out of view.
NOTE:
This publication also provides tables to
interpret these codes.
232
REPAIR CODE is an error summary of events that
occurred after power up. If the code is 000000, no
faults have been detected.
AP ENG CODE explains why the autopilot does
not engage. The code names all the conditions
that currently prevent the AP engage.
AP DIS CODE explains why the autopilot
disengaged itself. This code latches to identify the
cause of the last AP disengage.
YD ENG CODE explains why the yaw damper
does not engage. This code names all conditions
that currently prevent the YD engage.
YD DIS CODE explains why the yaw damper
disengaged itself. This code latches to identify the
cause of the last YD disengage.
STEER CODE explains why flight director fail (FD)
annunciated on the PFD. This code names all
conditions that are currently causing the flight
director to fail.
NOTE:
The BOOST CODE is not used for the
Challenger 605 airplane.

rudder boost input data error is detected. This
means that data from the engine pressure sensors
is not reasonable, or that these values do not
agree with the cross-side FCC values. The
BOOST DATERR report parameter lists the
number of detected data errors. Suspect a failed
pressure sensor or the FCC. Further investigation
is required.
BSTMON.... (Not used for the Challenger 605 airplane). A
rudder boost computation error is detected. This
means that an unnecessary rudder boost
occurred, or that the boost is in the wrong
direction. Cycle the remote RUD BOOST switch to
clear this error. The BOOST ERRORS report
parameter lists the number of detected
computation errors. Suspect the FCC.

Table 152 (continued)
Report Mode Monitor Values
RUDPWR... The rudder actuator has no power. This is caused
by a pulled circuit breaker, broken wiring, or
activation of the limit switch in the rudder actuator
at high IAS. The RUDPWR report problem also
occurs whenever IAS data is invalid.
SSMFCS .... A monitor from the servo switching module (SSM)
is bad, affecting the flight control system (autopilot
or yaw damper). SSMFCS is an O-Ring of the
SSM-AP and the SSM-YD logic.
SSM-AP ..... The servo switching module has detected a
problem with its switching of autopilot related data
between the two pairs of FCCs. The problem is
related to switching of the pitch servo, roll servo,
and/or pitch trim system.
SSM-YD..... The servo-switching module has detected a
problem with its switching of yaw damper related
data between the two pairs of FCCs. The problem
is related to switching of the yaw servo.
STRP-E...... External aircraft strapping is not compatible with
the FCC configuration ROM. Either the IAPS
configuration strapping is incorrect or the FCC has
an incorrect software version.
SVO-AP ..... An autopilot (pitch or roll) servo amplifier error is
detected. This term sets with SVO-P or SVO-R.
Refer to the AMP-P ERRORS and the AMP-R
ERRORS report parameters to isolate pitch/roll
error. Suspect the AHC, FCC, pitch/roll servos, or
mismatched discrete inputs. Further investigation
is required.
SVO-P........ A pitch axis servo amplifier error is detected. This
means that either a hardware failure occurred, or
that the inputs to the two halves of the pitch servo
amplifier are not alike. Suspect the AHC, FCC,
pitch servo, or mismatched discrete inputs.
Further investigation is required.
SVO-R ....... A roll axis servo amplifier error is detected. This
means that either a hardware failure occurred, or
that the inputs to the two halves of the roll servo
amplifier are not alike. Suspect the AHC, FCC, roll
servo, or mismatched discrete inputs. Further
investigation is required.
248
Table 152 (continued)
Report Mode Monitor Values
SVO-YD ..... A yaw damper servo amplifier error is detected.
This means that either a hardware failure
occurred, or that the inputs to the two halves of
the yaw servo amplifier are not alike. Suspect the
AHC, FCC, yaw servo, or mismatched discrete
inputs. Further investigation is required.
TRIM .......... A trim (pitch or roll) system failure is detected.
Check the TRIM-P ERRORS report parameter to
isolate the pitch or roll failure. Suspect the aircraft
pitch/roll trim system or the FCC.
TRMANN.... The trim (pitch or roll) fail annunciator test failed.
Suspect an annunciator bulb.
WRP-AP..... An autopilot (pitch or roll) wraparound error is
detected. Check the WRAP-P ERRORS and
WRAP-R ERRORS report parameters to isolate
the pitch or roll failure. Suspect the FCC.
WRP-Y....... A yaw axis wraparound error is detected. Suspect
the FCC.
WRP-YD .... A yaw damper wraparound error is detected.
Suspect the FCC.
WSWRN..... A windshear condition has been detected. This
includes a windshear warning from an
EGPWS/GPWS (or other external device) and
radio altitude and IAS within predefined limits.
XSLATA ..... There is an excessive lateral acceleration
problem. The XSLATA report occurs when there
has been excessive or invalid lateral acceleration
for too long, while at a high IAS.
YD DIS....... The yaw damper is disengaged. The yaw damper
must be engaged before the autopilot can engage.

INPUT MODE Page
To view the INPUT MODE page, perform the steps
that follow.
1. Show the STATUS MENU.
2. Move the cursor to the FCC DIAGNOSTICS
line.
3. Push the MENU PUSH SELECT button on the
CCP.
4. The REPORT MODE shows. Simultaneously
push any two FCP mode buttons to select the
INPUT MODE.
5. Use the Vertical Speed (VS) wheel to show
the next or the previous item on the cursored
line.
250
The INPUT MODE page lists input signal
information that is received by the FCC
computers. This mode is especially useful for
isolating a failed unit that supplies data to the
FCCs.
251
The INPUT MODE DIAGNOSTIC page shows five
lines of input signals. Each line contains the
SIGNAL NAME, a LEFT FCC VALUE, a RIGHT
FCC VALUE, and a unit of measure (if applicable).
The FCP mode buttons and VS wheel control the
INPUT MODE operations.
The SIGNAL NAME column lists five input signals.
The LEFT FCC VALUE column shows the signal
value at the input of the left FCC. The RIGHT FCC
VALUE column shows the signal value at the input
of the right FCC.
A yellow cursor shows at the left edge of the name
column. The cursor indicates which signal line is
active. The input mode parameters are listed in
alphanumeric order. Roll the VS wheel up to show
the previous parameter on the cursored line. Roll
the VS wheel down to show the next parameter on
the cursored line.
The display source indicator is an arrow that
points left or right to indicate which FCC is
providing display data to the MFD.
252
IOC labels are shown below the five signal lines in
both the LEFT and the RIGHT columns. The label
in the LEFT column indicates which IOC-3 input
bus (IOC-LA or IOC-LB) is currently being used by
the left FCC computer. The label in the RIGHT
column indicates which IOC-3 input bus (IOC-RA
or IOC-RB) is being used by the right FCC. The
operator can switch to the other IOC bus by
manually engaging, then disengaging, the
autopilot (e.g., push the AP engine button, then
lower the AP DISC bar on the FCP). Both FCCs
then use the other IOC bus, if it is valid.
The Input Mode Parameter List shows all available
input signal parameters. The most useful inputs
are decoded and displayed with a unit of measure
(e.g., feet or degrees) so that this value can be
easily compared with related displays or other
indications in the aircraft. The SOURCE LRU
column names the unit that generates that input
signal and the source word label. This column also
names the data bus (IOC-3, AHC-2, etc) that
supplies this information to the FCC. ARINC data
words are organized as follows.

External (non-FCC) data are shown as two input
signal parameters. One parameter is a descriptive
name and the other is an SSMPSI parameter.
These two parameters can be displayed to show
all pertinent information provided in the input data
word. For example, preselect altitude information
is provided in the 102 word. This information is
presented in the ALTREF and 102 parameters.
The ALTREF input parameter shows the preselect
altitude setting in feet. This information is decoded
from the primary data (bits 14 through 29) of word
102. Some primary data is not decoded into a
signal value, but instead is shown as a
hexadecimal value. The unit of measure for these
signals is displayed as 29-14H.
The 102 input parameter shows the remaining
pertinent information in three digits. The unit entry
on this line is SSMPSI. This means that the three
displayed digits are (in order): the SSM, Pad data,
and the SDI.
A typical SSM digit is 0 (Failed), 1 (No Computed
Data), 2 (Unit in Test), or 3 (Normal). This digit is
decoded from bits 30 and 31 of the input word.
The Pad digit lists miscellaneous information that
is normally pad (0 = Not Used) or secondary data.
This digit is decoded from bits 11, 12, and 13 of
the input word. The SDI digit is normally 0 (Not
Used), 1 (Left LRU), 2 (Right LRU), or 3 (Not
Used). This digit is decoded from bits 9 and 10 of
the input word.

OUTPUT MODE Page
1. Show the STATUS MENU.
2. Move the cursor to the FCC DIAGNOSTICS
line.
3. Push the MENU PUSH SELECT button on the
CCP.
4. The REPORT MODE shows. Simultaneously
push any two FCP mode buttons to select the
INPUT MODE. Repeat to select the OUTPUT
MODE.
261
This page lists the selected outputs from the
FCCs. These outputs may be controlled if both
FCCs are in diagnostics mode and the airplane is
on the ground. Five selectable parameters show
output signals from the LEFT FCC or RIGHT FCC.
Use the FCP mode buttons to select the output
mode operations. Use the VS wheel to change the
output signal parameter on the cursored line.
The Output Mode Parameter List describes each
parameter available for display. This table lists a
signal description and the modification range for
each parameter.
The FCC outputs always show, but they can only
be controlled when both computers are in
diagnostic mode (use both FD buttons on the
FCP; TEST annunciates on both PFDs). If it is
possible to control (modify) an output, the word
MODIFY shows as a column heading. If the active
(cursored) line can be modified, then EITHER,
BOTH, LEFT, or RIGHT shows on that line in the
MODIFY column.
Note that the EITHER and BOTH modify options
are not available unless both FCCs are in the
OUTPUT MODE (not just in diagnostics). Push the
XFR button (on the FCP) to alternately select leftand right-side display data to make sure that both
FCCs are in output mode.
When EITHER shows in the MODIFY column, the
left and right FCC logic outputs can be modified
independently. Push the left FD button, on the
FCP, to change the logic output of the left FCC.
Push the right FD button to change the logic
output of the right FCC.
262
When BOTH shows in the MODIFY column, the
left and right FCC linear outputs can be modified
synchronously. Push and hold the left FD button,
on the FCP, to synchronize both linear outputs to
the master FCC value, then change both outputs
in a minus direction.
Push and hold the right FD button to synchronize
both linear outputs to the master FCC value, then
change both outputs in a plus direction. The
master FCC is the one that supplies display data
to the MFD (indicated by the arrow on the center
of the page and selected by the XFR button on
FCP).
When LEFT shows in the MODIFY column, only
the left FCC output can be modified. When RIGHT
shows in the MODIFY column, only the right FCC
can be modified. Push an FD button, on the FCP,
to change the modifiable output.
The display source indicator (arrow) points left or
right to indicate which FCC supplies display data
to the MFD. In the output mode, this indicator is
especially useful.
Both FCCs must be in the output mode (not just in
diagnostics) to fully utilize the modify options.
Since only one FCC supplies display data to the
MFD, it is helpful to push the XFR button, on the
FCP, and check the selected mode of the other
FCC before beginning troubleshooting effort using
the output mode. The arrow also indicates the
(controlling) master FCC when both outputs are
synchronously changed.
263
The output mode can be used to drive the servos.
First, set the 65APMN, 65YDMN, 86APEN, and
86YDMN parameters to TRUE. This sets the FCC
internal monitors to a valid condition. Then set the
AILCUT, ELECUT, and RUDCUT parameters to
FALSE. This sets the FCC cutout logic so that the
system can engage.
Next, engage the yaw damper and autopilot.
Select the AILCMD (or ELECMD/RUDCMD)
parameter and move the cursor to this line. Push
the left or right FD button to apply a servo
command voltage. The control wheel (or control
column/rudder pedals) should move as the servo
runs. The AP, YD, and CUT parameters must
remain set as described above or the system will
not engage.

Servo Spin Test Procedure
If the autopilot disconnects intermittently and a
servo feedback problem is suspected, use this
procedure to test the servo-error feedback.
NOTE:
Do not engage AP or YD during this
test.
NOTE:
Use MFD on-screen instructions to
control FCC diagnostics.
1. Enter diagnostics on both FCCs.
2. Verify both PFDs display the word FCC TEST
in amber.
3. Enter INPUT MODE on either the left or right
FCC.
4. Move the cursor > to the top row, and use the
FCP VS wheel to display ASVOER (e.g.,
aileron servo error).
5. Move the cursor > to the next row, and use the
FCP VS wheel to display ESVOER (e.g.,
elevator servo error).
6. Verify ASVOER and ESVOER voltages (left
and right side locations) are less than ±0.20 V
dc.
NOTE:
The voltage can change. Use the
average voltage. Momentary peaks can
be ignored. Voltages need not be equal
and opposite.
7. Enter OUTPUT MODE on one FCC, then
push the XFR (e.g., transfer) button on the
FCP and enter OUTPUT MODE on the other
FCC. Push the XFR button again to return to
the selected FCC.
266
8. Move the cursor > to the top row, and use the
FCP VS wheel to display AILCMD (e.g.,
aileron servo command).
9. Move the cursor > to the second row, and use
the VS wheel to display ELECMD (e.g.,
elevator servo command).
10. Move the cursor > to the top row, and use the
FCP VS wheel to display AILCMD.
NOTE:
Make sure to move between OUTPUT
MODE and INPUT MODE quickly to
perform the steps that follow. First,
make sure to read all of the steps that
follow. Then perform the steps that
follow.
11. Push and hold the left FD switch on the FCP
until the AILCMD voltage is more than 9.00 V
dc.
12. Make sure the left and right voltages are equal
but opposite polarity. Left is minus polarity and
right is positive polarity.
13. Quickly enter INPUT MODE. Monitor
ASVOER for at least two minutes.
14. After two minutes, verify left and right voltages
are less than ±1.00 V dc.
15. Enter OUTPUT MODE and repeat steps 11,
12, 13, and 14 for the elevator servo (e.g.,
ELECMD and ESVOER).
16. Exit FCC diagnostics on both FCCs.
17. Make sure the TEST annunciation is removed
from both PFDs.
18. Exit maintenance diagnostics.
267
19. Power-down avionics.
NOTE:
To reverse servo command, push and
hold the opposite FD button on the
FCP. Reversing direction several times
can reduce servo-error voltages to
within tolerance.
SVL- 4000 Procedure
1. If the yaw damper disconnects intermittently
and a feedback problem is suspected, use this
procedure to test the servo-error feedback.
NOTE:
Both IRUs must be online before
starting this test. Turn on the hydraulics
system.
2. Set the pedestal mounted AFCS SEL knob to
select the desired pair of FCC computers.
3. Disengage the autopilot.
4. Engage both yaw dampers.
5. Show the MAINTENANCE MENU page.
NOTE:
Use MFD on-screen instructions to
control the FCC diagnostics.
6. Enter diagnostics on both FCCs and verify
both PFDs display FCC TEST in amber and
the MFD shows the REPORT MODE.
7. Enter INPUT MODE by pushing any two mode
buttons on the FCP. Make sure the MFD
shows the INPUT MODE.
8. Move the cursor > to the top row by pushing
any button on the FCP.
9. Use the FCP VS wheel to display RSVOER
(e.g., rudder servo error).
10. Push the XFR button on the FCP.
268
11. Place both FCCs in OUTPUT MODE, using
the FCP XFR button, to change between leftside and right-side FCCs.
Both FCCs must be in OUTPUT MODE
NOTE:
to proceed.
12. Set the 65APMN, 65YDMN, 86APEN, and
86YDMN to TRUE on both left and right
FCCs.
WARNING:
THE RUDDER MOVES DURING
STEP 13.
13. Set RUDCUT to FALSE in both left and right
columns.
NOTE:
Make sure to move between OUTPUT
MODE and INPUT MODE quickly
during the steps that follow. First, make
sure to read all of the steps that follow.
Then perform the steps that follow.
14. Select RUDCMD. The cursor > must be
adjacent to this value. Make sure that the left
and right columns indicate a value close to
0±0.02 vdc. If not, then use the FCP left or
right FD button to adjust this value.
15. Select INPUT MODE. Verify that RSVOER is
0±1.0 vdc.
NOTE:
If rudder command voltage is
exceeded, it can trip all monitors into an
off condition. This condition requires the
test to be restarted.
16. Select OUTPUT MODE. Use the FCP left FD
button to adjust the RUDCMD value to
-5.00±0.02 vdc.
17. Quickly select INPUT MODE. Make sure that
the RSVOER is 0±1.0 vdc in both left and right
columns.
269
18. Select OUTPUT MODE. Use the FCP right FD
button to adjust the RUDCMD value to
5.00±0.02 vdc.
19. Quickly select INPUT MODE. Make sure that
the RSVOER is 0±1.0 vdc in both left and right
columns.
NOTE:
To reverse the SVL-4000 command,
push and hold the opposite FD switch
on the FCP. Perform this procedure as
required to reduce the rudder servo
error voltages to fall within tolerance.
Corrective action: If, during the test supplied
above, the rudder servo error (e.g., RSVOER) is
not correct for the left or right side, a problem SVL4000, FCC-4006, or a wiring problem can be
expected.
•
Swap the FCCs. Perform the tests again to
see if the same results can be observed. If the
same results are observed, then continue to
step 2 above. If the incorrect reading changes
sides, replace the FCC that supplies the
incorrect results.
•
On the side (e.g., left or right) with the failed
results, use a meter to check the wiring
between the FCC and for continuity and
shorts. If no wiring problems are found,
replace the SVL and perform the test again.
On the side (e.g., left or right) with the failed
results, use a meter to check the wiring
between the FCC and the SVL for continuity
and shorts. If no wiring problems are found,
replace the SVL and perform the test again.
