Aprilia RX 125 Fault Codes
Aprilia RX 125 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 rx 125 faults are the list of some of the parts of a motorcycle engine.
What’s wrong with my Aprilia RX 125 motorcycle brake light and what can I do about it? There are a few possibilities. One is that your break switch is defective and will need to be replaced. Another is that your brake fluid level may be low.
Aprilia RX 125 Faults :
Another drawback that may occur along with your bike engine could be a blown gasket. this will cause your engine to overheat and presumably crack the cylinder heads. during this case, it's best to require your Aprilia RX 125 bike to an expert mechanic to possess it verified. Another common drawback is with the carburettor. The carburettor is that the a part of your bike that mixes air and fuel to make the combustion required to power the engine.
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
