Adaption Processes

Model Affected:

All models with Fuel Injection

This Technical News item has been created to remind dealers of the various adaptions used by our
motorcycles. The status of each of these adaptions can be examined using the Triumph Diagnostic Tool.
Currently, the adaptions are:
1. Engine Adaption
2. Neutral Position Adaption
3. Crankshaft Position Adaption - Euro 5 Motorcycles in Applicable Markets Only
4. Gear Position Adaption - Models fitted with Triumph Shift Assist Only
5. Shift Force Sensor Adaption (Triumph Shift Assist)
Further information about each of these adaptions can be found in the Triumph Diagnostic Tool User Guide
and relevant Service Manual.

1. Engine Adaption
General Information
The engine management system fitted to this model is adaptive. This means that the system is able to learn
about new or changing operating conditions. The fuelling and throttle system can continuously adapt itself
without needing to constantly make major adjustments from a fixed baseline setting.
Adaptive changes can become necessary because of different fuels, changes in the region in which the
motorcycle is operated (i.e. operation at high altitude where it was previously used at sea level) or because a
new part may have been fitted which has slightly different characteristics to the old part. Fuelling and
throttle system adaptive changes are automatic and require no intervention by rider or dealer.

Terminology
Where the term 'status' is used, this indicates how far the present operating parameter is from the stored
(adapted) value. The nearer these figures are to zero the better as it indicates the motorcycle has adapted
to its current operating conditions.

The term 'range' indicates how much (in percentage terms) of the adjustment range has been used to reach
the current operating status.

Forcing Adaption to Take Place
If the read out indicates that the motorcycle is not adapted, the following will force the system to make
adaptions:

Warning
Never start the engine or let it run for any length of time in a closed area. The exhaust fumes are
poisonous and may cause loss of consciousness and death within a short time. Always operate the
motorcycle in the open-air or in an area with adequate ventilation.
Note:
•

Resetting adaptions with the motorcycle connected to an exhaust extraction system may cause
incorrect values to be set, causing poor engine running. Always reset the adaptions with the engine
disconnected from any exhaust extraction system whilst ensuring the motorcycle is positioned in a
well ventilated area.

1.
2.

Ensure the engine is cold.
WITHOUT TOUCHING THE THROTTLE, start the engine and allow it to warm up until the cooling fan
comes on.
Turn the ignition OFF for at least 60 seconds to allow the adaption settings to be stored in ECM
memory.

3.

Resetting the Adaptions
A reset engine adaptions facility is provided in the diagnostic tool. This function can be used to:
• Force fast fuelling and throttle adaption.
• Reset (erase) current adaptions.
Fast Fuelling and Throttle Adaption
To force the fuelling and throttle system to quickly adapt to the current operating conditions:
1.
Connect the diagnostic tool and turn the ignition ON.
2. Start the engine.
3. Allow the engine to reach normal operating temperature (90°C for liquid cooled models, 60°C for air
cooled models).
4. Make sure the system is in closed loop control mode.
5. Navigate to Engine Diagnostics - Adjust.
6. Select 'RESET ENGINE ADAPTIONS' and click 'ADJUST'.
Note:
•

This will force a fast adaption routine to take place in around five seconds. For this to happen, the
engine MUST be running, it must be at normal operating temperature and in closed loop control mode.
Under any other conditions fast adaption will not take place and the current adaption settings may be
erased as described below.

Technical Bulletin 205 Issue 1

Reset (Erase) Current Adaptions
To reset the currently stored adaptions:
1.
Connect the diagnostic tool and turn the ignition ON. Do NOT start the engine.
2. Navigate to Engine Diagnostics - Adjust.
3. Select 'RESET ENGINE ADAPTIONS' and click 'ADJUST'.
The following adaptions will be reset:
• Fuelling
• Throttle
• Twist Grip
• Crankshaft Position (Euro 5 Motorcycles in Applicable Markets Only)
Note:
•
•
•
•

The following adaptions will not be reset:
- Neutral Position
- Gear Position
- Shift Force Sensor (TSA)

To Re-Adapt
1.
Connect the diagnostic tool and turn the ignition ON.
2. Start the engine.
3. Allow the engine to reach normal operating temperature (90°C for liquid cooled models, 60°C for air
cooled models).
4. Adapt the crankshaft position (see Crankshaft Position Adaption - Euro 5 Motorcycles in Applicable
Markets Only).
5. If applicable, perform a cruise control switch check as described in the Service Manual.

Fault Indications
If 'range' figures at 100% are seen, then the adjustment has reached maximum indicating a mechanical fault
exists on the motorcycle. This can be due to a number of faults but possible causes will be incorrect fuel
pressure, incorrectly connected oxygen sensors, faulty injectors or air leaks at the throttle bodies or airbox.
In these circumstances, locate and rectify the fault, and reset the adaptions as described above.

2. Neutral Position Adaption
The neutral position adaption is required to allow for manufacturing tolerances of the gearbox and gear
position sensor. The motorcycle is delivered from the factory with the neutral position fully adapted.
The neutral position adaption must be reset and re-adapted under the following conditions:
• If a gear position sensor malfunction occurs (DTC P0914, P0915 (if applicable) and P0917, see Gear
Position Sensor in the Fuel - Pinpoints section in the Service Manual).
• The gear position sensor has been removed or disconnected for any reason.

Technical Bulletin 205 Issue 1

Adaption Reset
The Gear Position/Neutral Position Adaption Reset function provided in the Triumph diagnostic tool will
erase all previous Gear Position/Neutral Position Adaptions.
To reset the Neutral Position adaptions:
1.
Connect the Triumph diagnostic tool and turn the ignition ON.
2. Make sure the engine stop switch is in the RUN (ON) position.
3. Select ENGINE DIAGNOSTICS.
4. Check and erase any stored DTCs.
5. Select ADJUST TUNE then select Gear Position/Neutral Position Adaption Reset.
6. Click Start.
7. The software will confirm that the adaption has been successfully reset.
8. The neutral position will now be reported as Not Adapted.

Re-Adaption

Warning
Exhaust fumes are poisonous, always operate a motorcycle in the open-air or in an area with adequate
ventilation.
Do not operate a motorcycle in an enclosed area without adequate ventilation.
Operating a motorcycle in an enclosed area without adequate ventilation can cause loss of consciousness
and death within a short period of time.
To re-adapt the neutral position:
1.
Ensure the transmission is in neutral.
2. Start the engine.
Note:
•
•
3.
4.
5.

For successful and accurate adaption, The engine must be at normal idle speed and the gear change
pedal and clutch lever must be in their normal rested position.
During adaption, do not raise the engine speed and do not touch or move the gear change pedal.
The neutral position will adapt shortly after engine start provided the above conditions are met.
The adaption status can be confirmed by selecting GEAR POSITION ADAPTION STATUS on the Triumph
diagnostic tool.
Turn the ignition OFF for at least 60 seconds to allow the adaption settings to be stored in ECM
memory.

3. Crankshaft Position Adaption - Euro 5 Motorcycles in Applicable Markets Only
Signals from the crankshaft position sensor are used by the motorcycle's engine misfire detection system.
In order to accurately detect an engine misfire, the crankshaft position must be adapted to allow for
manufacturing and assembly tolerances.
The motorcycle is delivered from the factory with the crankshaft position fully adapted. If for any reason
the crankshaft position is not adapted, the Malfunction Indicator Light (MIL) will be illuminated and DTC
P0315 will be stored.
In service, the crankshaft position must be re-adapted under the following conditions:
• The MIL is illuminated and DTC P0315 is stored, indicating that the crankshaft position sensor is not
adapted.
• The crankshaft position sensor has been disturbed, removed or disconnected.
• The crankshaft position sensor has been replaced.
• The crankcases have been disassembled/reassembled.
• The engine ECM has been replaced.*
• The engine adaptions have been reset using the 'Reset Engine Adaptions' function in the Triumph
diagnostic tool.*
* Under these conditions, the MIL is illuminated and DTC P0315 will be stored.
