Triumph Street Twin Fault Codes
Triumph Street Twin 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 street twin faults are the list of some of the parts of a motorcycle engine.
Checking the fault code is one of the most overlooked aspects of maintaining Triumph Street Twin motorcycle. Many people don’t think about it until something goes wrong. A clogged afuel pump. Now that you know how to stay visible on your bike, and how to stay safe on your Triumph Street Twin bike, it’s important that you know what you need. When you’re on a bike, the weather is often a factor. Here are a few tips that will help you protect yourself the next time you take your motorcycle out on the road.
Triumph Street Twin Faults :
Engine management systems of Triumph Street Twin 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. |

Issues with the engine area unit generally caused by problems with the engine elements. whether or not it's a fuel issue or AN ignition drawback, the engine elements ought to be inspected to work out the cause. Another issue that may occur is once the bike engine isn't operating could be a failure of the electrical system. this will cause the bike to stall and not work properly. The Triumph Street Twin electrical system is often the foremost complicated system on a motorbike.
