Triumph Grand Prix Fault Codes
Triumph Grand Prix motorcycles have engines, which are made up of many different parts. These parts must work together in order for the engine to function. A problem with one of the parts can make the engine not run. There are many different parts that make up an engine. The following triumph grand prix faults are the list of some of the parts of a motorcycle engine.
One of the most common issues with Triumph Grand Prix motorcycle electrical systems is a clogged battery terminal. This can cause your ride to start having issues with the electrical components. Discolored terminals are often caused by a build-up of corrosion. This will prevent electrons from flowing properly, which reduces your ride’s electrical performance.
Triumph Grand Prix Faults :
Engine management systems of Triumph Grand Prix are responsible for monitoring a range of features and its warning light should go out a few seconds after ignition. The system's main job is to keep the engine running at peak performance by monitoring many parameters like coolant temperature, oil pressure, fuel level and air/fuel ratio. The system monitors these parameters continuously and alerts the driver if any of these parameters fall outside the predetermined limits.
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 :
Symptom | 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. Crankshaft trigger wheel out of tolerance. | Investigate potential mechanical faults. Contact Triumph Service. |
