Aprilia Leonardo 250 Fault Codes
Aprilia Leonardo 250 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 leonardo 250 faults are the list of some of the parts of a motorcycle engine.
The oil level of Aprilia Leonardo 250 should be the same level in the dipstick, even when the engine is cold. You can check the oil level by removing the dipstick, holding the dipstick in your hand, and then reinserting the dipstick. Then, you’ll be able to see where the oil level is.
Aprilia Leonardo 250 Faults :
The warning light comes on when one of the various sensors has detected an abnormal condition in the Aprilia Leonardo 250 engine's performance. For example, if the oil pressure drops below a certain threshold or if the air/fuel ratio rises beyond a certain point, then this would cause an immediate alert from your vehicle's engine management system.
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
