Mercury G3 Service Tool Training Overview

Mercury G3 Service Tool Training
1. Connect your G3 cable USB to computer and install drivers so cable
can communicate with G3
2. If connecting to Axius or Zeus models, connect the 10 Pin on the G3
cable to the standard 6 or 8 way junction box for communication. On
Axius it could also be plugged into the 10 Pin engine connection by
removing the weather cap. (Yellow resistor on DTS engines)
3. EC Engine connections, remove Yellow terminator resistor on engine
harness. Use a 10 pin female to female connection to a 4 way J-box,
install Yellow terminator from engine harness on to 4 way J-box.
Female to female adaptor from 4 way to engine harness and G3 cable
plugs into 4 way. You must keep the terminators on the CAN bus!

When opening G3 you
will start at this screen
first import thing to look
for is communication
Red lights on both CAN P
and CAN H indicate that
the cable is not detected
by G3 (check connection
at USB on Computer)
Yellow lights on CAN P
and CAN H indicate the
cable is detected but no
response from Modules
on CAN bus. Check
power supply
Cable Connection
problem One CAN Bus
is not detected in cable.
Check Settings on
Cable look at following
Click on YES to change options this will allow channel change on
CAN H since it shows to not be set. You would select Ch. 1 with
CAN P mapping on Ch. 0
When you click on yes you will get this Options box which will allow
you to set channel. Set CAN H to Ch. 1 and click save to apply.
G3 cable is now
detected by G3 tool. It is
not communicated at
this point, only showing
that it G3 tool sees
G3 is now communicating
on CAN Bus to ping
modules and you are ready
to select the EBOM to
establish communication
to Engine/Helm/TVM for
Axius or just Engine for
EBOM stands for Electronic Bill
of Material and each contains all
software sets for communication
As the tool is pinging modules the EBOM will start to
populate with the proper build of which you can
communicate with and see data stream information
from the module(s)
Under 6.2 Bravo the tool has indicated there are 10 modules on
the CAN Bus. You can select the drop down box to see the
module City ID’s that are in this selection. You will then click on
the select button to pick this data set to communicate with.
The next button after
EBOM is Configuration
which is used for the
vessel set up.
Start Here
The Compass Calibration Wizard will
walk you through all the steps to
properly calibrate the compass and
complete the Validate Compass
Configuration. You can start there or
start at the compass Linearization tab
if magnetic interference is a known
issue in the vessel area.
If starting at Compass
Linearization you will walk
through the remaining steps as
well to Validate Compass
From the main configuration screen you
will choose Helm Configuration to set up
helms. In the helm config menu you will
see the City ID’s on the CAN bus for
CCM’s that are configured.
On a new Axius set up that was not configured there would only be a Starboard
Outside CCM. The software establishes a city ID 92 on the Helm Set Up as there
is only one CCM SRZ file. Helm set up will need to be completed to see a City ID
92 on Port Outside.
Current Configuration not set up as City ID 91
is in Red. Set number of engines as shown
on next slide.
Set number of Engines with drop down box.
Click on Helm Setup to walk through configuration
Both Levers in Neutral and press next to
Move Stbd Only lever, then press Next
Now move Port lever to RWOT and click
Move Both Levers to Neutral and click
After clicking next the Turn Keys Off screen will
appear, turn keys off, then click OK
After turning keys back on press the OK button
Helm has been adapted, click the OK button to
proceed with Lever Configuration.
Go to Lever Adapt, choose lever type and set shift polarity
and adapt all if setting up a new vessel, then click the start
button. Make sure helm selection is on appropriate Helm for
The warning pop up window will appear when you
click start telling you that handles must be completely
adapted for engines to start.
From Step 1 through Step 6 you will move both levers from RWOT to
FWOT and then back to Neutral. After each step you will click the Next
button at bottom right of screen
This is the last of the
6 steps, click Next at
this point
This pop up window will appear, turns keys off then press
the OK button to continue.
Once Helm Config is completed, you
will do a steering wheel adapt. If
steering wheel adapt is not completed
before Drive Initialization a

Select Helm # and proceed in this slide there
is no CCM online so process is not allowed
Trackpad Configuration will
allow you to see current City
ID locations as well as
reconfigure the City ID
Once in Trackpad Configuration it will show you current trackpads on
CAN P and CAN H with City ID’s. You can retore city id or assign track
pads to new city ID’s. All ERC Track pads are on CAN P while Axius
Precision Pilot screens are on CAN H
Drive Alignment screen is an On
Water set up, vessel must be in
water to complete
Manual Drive alignment is usually
done when drives are installed at
OEM. It may need configured at
Dealer if drives are removed or
transoms replaced. The Vessel
must be out of the water for this set
up. 4 way valve is unlocked on TVM
to allow drive to move by hand. It
will require some force to move
Drive initialization will need to be
completed if on key up a TVM NonCritical fault appears or if linear
sensors have been replaced, or if
software is updated. G3 is not yet
capable of installing Current table
shift or hysteresis values.
Select drive to initialize either port or starboard or
both. On small block applications only select one
drive if the opposite drive location is center or
outward of center position as drives could touch.
It is best to have engines above idle speed and
make sure battery voltage is sufficient to
Import function is to import the
boat personality. This was done
before with a USB into the
vesselview. One difference to be
noted is that the personality name
will not appear in VesselConfig –
All Modules screen
Module data screen will allow you to see all modules on CAN Bus
and look at Data Stream, Faults and Freeze Frame and Run
History on Engine PCM’s.
Active Tests screen,
only tests that are
highlighted are
function so tests will
be limited to module
Not Available
Not Available
This is only a screen shot for
demonstration, Tests available are
dependent on the PCM capabilities.
Print screen option, data logging is not available on first release but print screen is.
You can click on this option and it will take a snap shot of data and file to
predetermined location. Data logging will be available on later updates.
Show Options allows you to change CAN Channel mapping or Screen Print output path.
Help Screen (?) allows you to see G3 System Specifications along with Vessel
Specifications which is help information on Chart plotters SW and Install.
Chart Plotter models, SW and installation are shown in the Vessel Specifications
