Systems Diagnostics
The management systems on this model have on-board diagnostic features which allows service technicians to retrieve stored data from the relevant electronic control module (ECM) using Triumph diagnostic software. Full details of the Triumph diagnostic software operation and how to interpret the results are given in the Triumph Diagnostic Tool User Guide.
The software allows the user to retrieve data associated with the system sensors and actuators, test various component functions, read build data and make minor adjustments to the set-up of the system.
To connect to the Triumph diagnostic tool see Diagnostic Tool Connection.
The DTCs are reported to the Triumph diagnostic tool as a five digit code.
When the system detects a fault, it begins to count the number of times the fault occurs before confirming the fault and storing a fault code. A confirmed fault may be indicated by the effected system(s) simply becoming inoperative, or by the illumination of a system warning light and/or instrument warning message.
Similarly, if a fault clears, the Instruments also records this fact and will extinguish any warning lights or instrument messages and restore normal operation to the affected system, when sufficient no-fault ignition switch cycles have taken place. Any fault codes will remain in the memory until the required number of no-fault ignition switch cycles have taken place. The number of ignition switch cycles required to restore normal operation will always be less than the number required to remove a DTC from the memory.
DTCs can be removed at any time using the Triumph diagnostic tool.
Engine ECM
Engine ECM
The on-board diagnostic system has two stages to fault detection. When a fault is detected, the DSM (Diagnostic Status Manager) raises a flag to indicate that a fault is present and increments a counter. The counter checks the number of instances that the fault is noted. For example, if there is a fault in the crankshaft position sensor, the counter will increment its count each time the crankshaft turns through 360°, provided the fault is still present.
When the count begins, the fault is detected but not confirmed. If the fault continues to be detected and the count reaches a predetermined threshold, the fault becomes confirmed. If the fault is an emissions related fault or a serious malfunction affecting engine performance, a DTC (Diagnostic Trouble Code) and freeze-frame data will be logged in the ECM's memory and the MIL (Malfunction Indicator Lamp) on the motorcycle instrument panel is illuminated. Once a fault is confirmed, the number of warm-up cycles made by the engine is counted. If the fault clears, the warm-up cycle counter will extinguish the MIL (Malfunction Indicator Lamp) at a predetermined count, and erase the DTC and freeze-frame data from the ECM memory at another (higher) count.
A single warm-up cycle is deemed to have taken place when the following criteria have been met:
The coolant temperature must be raised to 72°C or more.
The coolant temperature must have risen by 23°C or more from its start temperature, when 72°C is reached.
A controlled power down sequence must take place.
Service Symbol
Service Symbol/General Warning Symbol
The service symbol will illuminate for five seconds after the motorcycle start up sequence as a reminder that a service is due in approximately 60 miles (100 km). The service symbol will illuminate permanently when the mileage is reached, it will remain permanently illuminated until the service interval is reset using the Triumph Diagnostic tool.
The general warning symbol will flash if an ABS or engine management fault has occurred and the ABS and/or MIL warning lights are illuminated. Rectify the fault and clear the diagnostic trouble codes using the Triumph Diagnostic tool.

ABS ECM
ABS ECM
Under normal operation, the ABS warning light will flash after the ignition is switched on and until the vehicle speed exceeds 6 mph (10 km/h). The ABS performs a self check and if no faults are found the flashing light is extinguished. If a trouble code is stored the ABS warning light will stay illuminated and the ABS will not function, however the brakes will operate as a non-ABS braking system. If the ABS warning light does not extinguish, or illuminates whilst the motorcycle is being ridden.
Dependant on the DTC stored, the ABS ECM will act in one of two ways:
Inhibit ABS operation immediately, irrespective of the ABS operating mode;
Allow the ABS operation to complete before inhibiting the ABS.
Once the ABS ECM has inhibited ABS function, the ECM will act in one of three ways:
Allow the ABS to resume operation if the fault clears;
Allow ABS operation after an ignition cycle if the fault clears;
Inhibit the ABS function until the fault is rectified and the DTC erased.

CAN errors
CAN Errors
The diagnostic trouble codes are reported to the Triumph diagnostic tool as a five digit fault code (DTC) followed by a four digit code (Failure Type).
