Crankshaft Position Adaption (European 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.

Preliminary Steps

  1. Make sure the transmission is in neutral.
  2. Connect the Triumph diagnostic tool and turn the ignition ON.
  3. Make sure the engine stop switch is in the RUN position.
  4. Navigate to ENGINE DIAGNOSTICS - Sensor Data - Inputs.
  5. Make sure the Gear Position Status is reporting as Neutral.
  6. Navigate to Sensor Data - Gear Position Adaption.
  7. Make sure the Neutral Position Adaption Status is reporting as Adapted.
  8. Reset and re-adapt the neutral position if any of the following conditions exist:
    9. * The Neutral Position Adaption is reported as Not Adapted.
    * The Gear Position Status is not reported as Neutral when the transmission is in neutral (regardless of the current Neutral Position Adaption Status).

See Neutral Position Adaption

note
If the neutral position adaption is reset and re-adapted, the ignition must be turned off for at least 60 seconds before starting the crankshaft position adaption process.

To Adapt the Crankshaft Position:

Warning - General - Confined Area Engine Running

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.
  1. Navigate to ENGINE DIAGNOSTICS - Function Test - Adapt the crankshaft position.
  2. Click Start.
  3. Follow the on-screen instructions.
    4. note
    The function test will check that the transmission is in neutral and that the neutral position is adapted. If these conditions are not met, the test will be aborted and you will be prompted to check the transmission and neutral adaption status.If the transmission conditions are correct, you will be prompted to start the engine and bring the engine up to the required temperature.Once the engine has reached the required temperature the test will progress automatically and you will be prompted to hold the throttle (twist grip) fully open.The test will be aborted if the throttle is not opened within 60 seconds.It is important that the throttle is held fully open during this stage of the test. The diagnostic tool will display a red light if the throttle is not in the correct position. The light will change to green when the throttle is held fully open.
  4. Hold the throttle fully open within 60 seconds of being prompted by the diagnostic tool. Do not close the throttle until instructed to do so by the diagnostic tool.
    5. note
    Upon holding the throttle open, the engine speed will increase and decrease in cycles at approximately one cycle per second. The cycles are repeated until the crankshaft position adaption is complete.Adaption is typically completed after the fourth cycle.You will be prompted to close the throttle when adaption has completed.The diagnostic tool will allow the test to operate with the throttle held open for a maximum of 10 seconds (approximately 10 cycles). If adaption is not completed in this time, the test will stop and you will be prompted to close the throttle and turn the ignition OFF. Note any on-screen messages and investigate the cause before attempting to restart the test.
  5. Close the throttle when prompted by the diagnostic tool.
  6. Note the results of the adaption and follow the on-screen instructions.
  7. Click Finish.
  8. Turn the ignition OFF as prompted by the diagnostic tool and wait for 60 seconds for the Engine ECM to fully power down.

Final Steps

Successful crankshaft position adaption can be verified as follows:

  1. Turn the ignition ON.
  2. Navigate to ENGINE DIAGNOSTICS - Read DTCs.
  3. Check that DTC P0315 has cleared.
  4. Check that the MIL light goes out when the engine is started.
note
The presence of other DTCs may cause the MIL light to remain illuminated. Where this is the case, rectify and erase any other stored DTCs as necessary.

Possible Causes

Action

Test is aborted immediately after clicking Start.

Transmission is not in neutral.

Neutral position is not adapted.

Neutral position adaption is in a state of error.

Check the transmission is in neutral.

Reset the neutral position adaption.

Start the engine and allow the neutral position to adapt.

Turn the ignition off for at least 60 seconds before restarting the crankshaft position adaption test.

Test is aborted after the engine has reached the required temperature.

The throttle was not held open within 60 seconds of the engine reaching the required temperature.

Turn the ignition off for at least 60 seconds before restarting the crankshaft position adaption test.

Make sure the throttle is held open within 60 seconds of being instructed to do so by the diagnostic tool.

Crank adaption failed.

Throttle was held fully open for 10 seconds before the diagnostic tool displayed an instruction to close the throttle.

Ignition was not turned off for 60 seconds after adapting the neutral position.

Turn the ignition off for at least 60 seconds before restarting the crankshaft position adaption test.

Crank adaption failed.

The diagnostic tool displayed an instruction to close the throttle at the expected time (after the forth engine revving cycle).

Adaption has completed abnormally.

Mechanical fault.

Crankshaft position signal out of range.
