Replacement Engine ECM Setup

Model Affected:

Speed 400, Scrambler 400 X

We would like to advise dealers that a specific electronic set up process is required when fitting a
replacement Engine ECM to the above models in service.
After installing a replacement Engine ECM, the following actions must be performed:
1.
Connect the Triumph Diagnostic Tool to the motorcycle and turn the ignition ON.
2. Make sure the engine stop switch is in the RUN position.
3. Write the motorcycle Vehicle Identification Number (VIN) to the Engine ECM.

NOTICE
Writing the VIN to the Engine ECM is a one time only function that is only available for set up of
replacement ECMs. Once a VIN has been written to the Engine ECM, it is not possible to write the VIN again.
Care must be taken to enter the VIN details correctly when writing the VIN. If the VIN is written incorrectly,
the motorcycle will not start and another replacement Engine ECM will have to be ordered.
The VIN being written to the Engine ECM must match the VIN engraved on the motorcycle frame.

Adapt the engine management system.

DANGER
Never start the engine or run the engine in a confined area.
Always operate the motorcycle in the open air or in an area with adequate ventilation.
Exhaust fumes are poisonous and will cause loss of consciousness and death within a short period of time.

NOTICE
Adapting the motorcycle while connected to an exhaust extraction system may cause incorrect values to
be set, causing poor engine running.
Always adapt the motorcycle with the engine disconnected from any exhaust extraction system but make
sure the motorcycle is positioned in a well ventilated area.

NOTICE
To ensure correct engine adaption, make sure that the engine is left to run at idle speed for the duration
of the process.
Do not rev the engine, operate the clutch lever or operate gear change lever during the adaption process.
Failure to observe the above can cause incorrect engine adaption and poor running.
• Start the engine and allow it to run at idle speed.
• Do not rev the engine, operate the clutch lever or operate gear change lever while the engine is
warming up.
• Allow the engine to warm up until the cooling fan turns on.
• Wait for the cooling fan to turn off, then turn the ignition Off.

Replacement ABS Modulator Setup

Model Affected:

Speed 400, Scrambler 400 X

We would like to advise dealers that a specific electronic set up process is required when fitting a
replacement ABS Modulator to the above models in service.
After installing a replacement ABS Modulator, the ABS Variant Code must be programmed using the
Triumph Diagnostic Tool:

WARNING
Always make sure that the correct motorcycle model name is selected when setting the ABS Variant Code.
Setting the ABS Variant Code to an incorrect motorcycle model can cause an unsafe riding condition which
could lead to an accident resulting in injury or death.

WARNING
Always make sure that the correct motorcycle model name is selected when setting the ABS Variant Code.
The Triumph Diagnostic Tool uses ABS Variant coding data to identify the motorcycle model when
performing pre download model identification scans for the Engine ECM, Instruments and Immobiliser.
Setting the ABS Variant Code to an incorrect motorcycle model can cause the diagnostic tool to incorrectly
identify the motorcycle model when performing pre download model identification scans. This can lead to
download of incorrect calibrations for your model.
Operating a motorcycle with incorrect ABS variant coding and incorrect calibrations installed can cause an
unsafe riding condition which could lead to an accident resulting in injury or death.

NOTICE
ABS Variant Code Programming is only required when installing a replacement ABS modulator.
The ABS Variant Code should not be reset or adjusted during normal motorcycle service.
