Aprilia Compay Fault Codes

Aprilia Compay 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 aprilia compay faults are the list of some of the parts of a motorcycle engine.

Aprilia Compay motorcycles are particularly vulnerable to exhaust fumes, so you’re right to be concerned about the fumes you breathed in. The good news is that you should be able to find a motorcycle maintenance checklist online or at your local dealership that will provide you with a list of potential issues that might be causing your bike to release harmful emissions.

Aprilia Compay Faults :

Engine management systems of Aprilia Compay 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.

Aprilia engine management system is able to self-diagnose faults and tell you what's wrong with it.

To display the Aprilia Fault Codes diagnostics codes, enable diagnostics mode by pressing the LAP button at key-ON for at least 15 seconds. To exit the diagnostics code display and return to the normal display mode, run a key-OFF/ON cycle. When the faults are eliminated and hence the Fault Code is no longer being sent to the dashboard by the ECU, the dashboard will continue to display them until a key-OFF/ON cycle is run. lithe dashboard is sent a code other than those given in the following diagnostics code table, it will display PXX where the XX ls the last iwo digits of the code in question. lf the CAN line does not respond or is disconnected in diagnostics mode, ERR will flash in place of the code digits
