Triumph Fault Codes

This Triumph manual provides the information required for normal servicing.

Diagnostic trouble codes (DTCs) are logged in the ECM memory when there is a confirmed fault in the system & are reported as a four digit code. The system will log the diagnostic trouble codes listed below (not all are applicable to every model).

When the system detects a fault, it begins to count the number of times the fault occurs before illuminating the MIL and storing a fault code. Similarly, if a fault clears, the ECM also records this fact and will turn off the MIL when sufficient no-fault warm-up cycles have taken place. Any fault codes will remain in the ECM memory until the required number of no-fault warm-up cycles have taken place. The number of warm-up cycles required to extinguish the MIL will always be less than the number required to remove a DTC from the ECM memory.

Triumph Motorcycle Troubleshooting :

SymptomPossible CausesAction
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. Crankshaft trigger wheel out of tolerance. Investigate potential mechanical faults. Contact Triumph Service.
