Examples of certain conditions are high rpm, full load and engine operating temperature.
Troubleshooting the symptoms under other conditions can give misleading results.
Active Diagnostic Codes or Engine Events
Certain diagnostic codes and/or event codes may cause poor performance. Connect the Caterpillar
Electronic Technician (ET) and check for active codes and for logged codes. Troubleshoot any codes
that are present before continuing with this procedure.
Incorrect Engine Rating
Verify that the correct engine rating is being used for the application.
Improperly Programmed Parameters
Check the following parameters on Cat ET:
Verify that the injector codes have been programmed properly.
"Throttle Position Sensor"
"Desired Speed Input Configuration"
"Direct Fuel Control Mode"
Determine the type of throttle that is used in the application. Program the parameters to match the type
of throttle that is used. Refer to the diagnostic functional test Troubleshooting, "Throttle Position Sensor
Circuit - Test" for more information.
Note: If the parameters are not programmed correctly, then the engine will have poor performance.
Cold Mode
Monitor the status screen on Cat ET in order to verify that the engine has exited cold mode.
Poor Electrical Connections
Check the associated wiring for damage, abrasion, corrosion or incorrect attachment on the following
connectors: J1/P1 and J2/P2 ECM connectors, customer connector and throttle position sensor
connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for information.
Incorrect Status of PTO Enable Switch
Connect Cat ET and verify that the "PTO enable switch" is not engaged. Remove the wiring for the PTO
enable switch and cycle the power to the ECM. Verify that the problem is still present. If the problem is
still present, reattach the wires and continue to next step. If the problem is resolved, refer to the
diagnostic functional test Troubleshooting, "Switch Circuits - Test".
Incorrect Status of Intermediate Speed Switch
https://sis.cat.com/sisweb/sisweb/techdoc/content.jsp?calledpage=/sisweb/sisweb/mediasear... 4/8/2010
Service Information System
Page 3 of 4
Connect Cat ET and verify that the intermediate speed switch is not engaged. Remove the wiring for
intermediate speed and cycle power to the ECM. Verify that the problem is still present. If the problem
is still present, reattach the wires and continue to next step. If the problem is resolved, refer to the
diagnostic functional test Troubleshooting, "Switch Circuits - Test".
Incorrect Throttle Signal
Connect Cat ET to the service tool connector. View the status for the throttle position on the status
screen. Operate the throttle from the low idle position to the high idle position. The status should be
approximately 0 percent at low idle and the status should be approximately 100 percent at high idle. If
the status cannot operate in the full range, refer to the calibration procedure Troubleshooting, "Throttle
Position Sensor - Calibrate".
Diagnostic codes that are related to the J1939 data link will prevent correct operation of the throttle if
the throttle position is transmitted over the data link. If there is a problem with the data link, the engine
will remain at low idle until the data link is repaired.
Poor Connections to the Electronic Unit Injectors
Inspect the J2/P2 ECM connector and the J300/P300 valve cover connector for proper connections.
Refer to Troubleshooting, " Electrical Connectors - Inspect". Connect Cat ET and cut out each cylinder
in order to isolate the misfiring cylinder or cylinders. If the results are inconclusive, shut off half of the
cylinders and repeat the cylinder cutout test on the active cylinders that are remaining in order to locate
those cylinders that are missing. Refer to the diagnostic functional test Troubleshooting, "Injector
Solenoid Circuit - Test".
Fuel Supply
Check for a problem with the fuel supply and verify the fuel pressure. Verify that a fuel pressure sensor
is installed on the engine. For further information, refer to Systems Operation/Testing and Adjusting,
"Fuel System Pressure - Test".
Turbocharger Outlet Pressure Sensor (Intake Manifold Air), Rated Fuel Position
and/or FRC Fuel Position
1. With the engine at full load, monitor "Fuel Position" and "Rated Fuel Limit" on the status screen.
If "Fuel Position" does not equal "Rated Fuel Limit", then check air inlet manifold pressure.
2. Verify that there are no active diagnostic codes that are associated with the turbocharger outlet
pressure sensor (intake manifold air) or with the atmospheric pressure sensor.
3. Monitor air inlet manifold pressure and atmospheric pressure for normal operation on the status
screen.
Air Inlet and Exhaust System
Check the air inlet and exhaust systems for restrictions and for leaks. Refer to Systems
Operation/Testing and Adjusting, "Air Inlet and Exhaust System - Inspect". Look for an indication of the
warning lamp or restriction indicators that are tripped if the filters are equipped with these devices.
These indicators are associated with plugged filters. Replace the plugged air filters or clean the plugged

air filters per the guidelines for operation and maintenance. Repair any leaks that are found in the
system.

Diagnostic Codes
SMCS - 1900
Diagnostic Codes
Diagnostic codes alert the operator that a problem in the electronic system has been detected. Diagnostic
codes are also used by the service technician to identify the nature of the problem. Caterpillar Electronic
Technician (ET) is a software program that is designed to run on a personal computer. The software can
be used by the service technician in order to view the diagnostic code information for an ECM.
Diagnostic codes may consist of the component identifier (CID), and the failure mode identifier (FMI).
Component Identifier (CID) - The CID indicates the component that generated the code. For example,
the CID number 1 identifies the fuel injector for the number one cylinder.
Failure Mode Identifier (FMI) - The FMI indicates the type of failure.
Suspect Parameter Number (SPN) - The SPN is a three digit code which is assigned to each
component in order to identify data via the data link to the ECM. This is used on the diagnostics for the
CAN data link.
Refer to Troubleshooting, "Diagnostic Code Cross Reference" for the complete list of the diagnostic
codes and a description of each code. There is a troubleshooting procedure for every diagnostic code.
Refer to Troubleshooting, "Troubleshooting With A Diagnostic Code".
When a diagnostic code is activated, the Electronic Control Module (ECM) transmits information about
the code over the J1939 data link. Some J1939 devices may display the code. However, the code will be
displayed with a SPN-FMI code. Refer to Troubleshooting, "Diagnostic Code Cross Reference" for a
cross-reference between SPN-FMI codes and diagnostic codes.
Do not confuse diagnostic codes with event codes. Event codes alert the operator that an abnormal
operating condition such as low oil pressure or high coolant temperature has been detected. Refer to
Troubleshooting, "Troubleshooting with an Event Code" for additional information on event codes.
Illustration 1 is an example of the operating range of a sensor.

Example of the typical operating range of a sensor
(1) This area represents the normal operating range of the engine parameter.
(2) In these areas, the engine is operating in an unsafe operating range of the monitored parameter. An event code will be
generated for the monitored parameter. The sensor circuit does not have an electronic problem. Refer to Troubleshooting,
https://sis.cat.com/sisweb/sisweb/techdoc/content.jsp?calledpage=/sisweb/sisweb/mediasear... 4/8/2010
Service Information System
Page 3 of 4
"Troubleshooting with an Event Code" for additional information on event codes.
(3) In these areas, the signal from the sensor is outside of the operating range of the sensor. The sensor circuit has an
electronic problem. A diagnostic code will be generated for the sensor circuit.
Active Diagnostic Codes
An active diagnostic code represents a problem with the electronic control system. Correct the
problem as soon as possible.
When the ECM generates an active diagnostic code, the "Active Alarm" indicator ("Engine Control
Alarm Status" on Cat ET) is activated in order to alert the operator. If the condition that generated the
code is momentary, the message disappears from the list of active diagnostic codes. The diagnostic code
becomes logged.
Logged Diagnostic Codes
When the ECM generates a diagnostic code, the ECM logs the code in permanent memory. The ECM
has an internal diagnostic clock. Each ECM will record the following information when a code is
generated:
The hour of the first occurrence of the code
The hour of the last occurrence of the code
The number of occurrences of the code
This information is a valuable indicator for troubleshooting intermittent problems.
A code is cleared from memory when one of the following conditions occur:
The service technician manually clears the code.
The code does not recur for 100 hours.
A new code is logged and there are already ten codes in memory. In this case, the oldest code is
cleared.
Some diagnostic codes may be easily triggered. Some diagnostic codes may log occurrences that did not
result in complaints. The most likely cause of an intermittent problem is a faulty connection or damaged
wiring. The next likely cause is a component failure. The least likely cause is the failure of an electronic
module. Diagnostic codes that are logged repeatedly may indicate a problem that needs special
investigation.
Note: Always clear logged diagnostic codes after investigating and correcting the problem which
generated the code.

Event Codes
SMCS - 1901
Event codes alert the operator that an abnormal engine operating condition such as low oil pressure or
high coolant temperature has been detected. When the event code is generated, the event is active.
Active Event Codes
An active event code represents a problem with engine operation. Correct the problem as soon as
possible.
Active event codes are listed in ascending numerical order. The code with the lowest number is listed
first.
When certain event codes are activated, the Electronic Control Module (ECM) also generates a flash
code that will be displayed on the diagnostic lamp. Refer to Troubleshooting, "Diagnostic Code Cross
Reference" for a cross-reference between event codes and flash codes.
Illustration 1 is an example of the operating range of an oil temperature sensor. Do not use the

Example of the typical operating range of an oil temperature sensor
(1) This area represents the normal temperature range for the engine oil. The normal output voltage of the sensor is between
0.2 VDC and 4.2 VDC.
(2) In this area, the oil temperature above 107 °C (225 °F) is higher than normal. The output voltage of the sensor will
https://sis.cat.com/sisweb/sisweb/techdoc/content.jsp?calledpage=/sisweb/sisweb/mediasear... 4/8/2010
Service Information System
Page 3 of 5
generate an event code. The sensor does not have an electronic problem.
(3) In these areas, the output voltage of the sensor is too high or too low. The voltage is outside of the normal range. The
electronic problem will generate a diagnostic code. Refer to Troubleshooting, "Troubleshooting with a Diagnostic Code" for
additional information on diagnostic codes.
The following format is used for event codes:
"EXXX (Y) Description of the event"
The "E" means that the code is an event code. The "XXX" represents a numeric identifier for the event
code. The "(Y)" represents a numeric identifier for the severity of the event. This is followed by a
description of the event. Refer to the following example:
"E004 (3) Engine Overspeed Shutdown"
In this example, the number 3 indicates the severity of the event. The ECM has three levels of response
to events:
Warning (1) - This condition represents a serious problem with engine operation. However, this
condition does not require a derate or a shutdown.
Derate (2) - For this condition, the ECM reduces the engine's power in order to help prevent possible
engine damage.
Shutdown (3) - For this condition, the ECM shuts down the engine in order to help prevent possible
engine damage.
Responses to certain events may be programmed into the ECM. Refer to Troubleshooting, "System
Configuration Parameters".
Logged Event Codes
When the ECM generates an event code the ECM logs the code in permanent memory. The ECM has an
internal diagnostic clock. The ECM will record the following information when an event code is
generated:
The hour of the first occurrence of the code
The hour of the last occurrence of the code
The number of occurrences of the code
Logged events are listed in chronological order. The most recent event code is listed first.
This information can be helpful for troubleshooting intermittent problems. Logged codes can also be
used to review the performance of the engine.
Clearing Event Codes
https://sis.cat.com/sisweb/sisweb/techdoc/content.jsp?calledpage=/sisweb/sisweb/mediasear... 4/8/2010
Service Information System
Page 4 of 5
A code is cleared from memory when one of the following conditions occur:
The code does not recur for 100 hours.
A new code is logged and there are already ten codes in memory. In this case, the oldest code is
cleared.
The service technician manually clears the code.
Always clear logged event codes after investigating and correcting the problem which generated the
code.
Troubleshooting
For basic troubleshooting of the engine, perform the following steps in order to diagnose a malfunction:
1. Obtain the following information about the complaint from the operator:
The event and the time of the event
Determine the conditions for the event. The conditions will include the engine rpm and the
load.
Determine if there are any systems that were installed by the dealer or by the customer that
could cause the event.
Determine whether any additional events occurred.
2. Verify that the complaint is not due to normal engine operation. Verify that the complaint is not
due to error of the operator.
3. Narrow the probable cause. Consider the operator information, the conditions of operation, and
the history of the engine.
4. Perform a visual inspection. Inspect the following items:
Fuel supply
Oil level
Oil supply
Wiring
Connectors
Be sure to check the connectors. This is very important for problems that are intermittent. Refer to
Troubleshooting, "Electrical Connectors - Inspect".

E190 Engine Overspeed Warning
SMCS - 7427-038
Conditions Which Generate This Code:
The trip point has been exceeded for engine overspeed protection.
System Response:
The Electronic Control Module (ECM) will log the event.
Note: The warning will be cancelled if the engine rpm drops 200 rpm below the trip point that is
programmed for this parameter.
Engine operation is not affected unless engine speed exceeds the maximum governed engine speed. If
the maximum engine speed is exceeded, the injection will be disabled until the engine speed drops
below the maximum engine speed.
The operator may be operating the engine incorrectly.
The "Engine Overspeed" parameter may be incorrectly programmed for the application. Use Caterpillar
Electronic Technician (ET) to view the parameter setting for engine overspeed. Refer to
Troubleshooting, "System Configuration Parameters" for the rpm range that is available for this
parameter.
