Aprilia Fault Codes

This Aprilia manual provides the information required for normal servicing.

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

These abbreviations, and the accompanying list of trouble codes, can be a great start when your Aprilia check engine light comes on. As mentioned above, if you are not comfortable with electrical diagnostic work, a dealership or qualified technician can offer assistance. Please keep in mind that even though you have the ability to clear a DTC using the onboard diagnostic feature, you shouldn't clear the code prior to your service appointment. Let the technician view and clear the codes as they troubleshoot the issue.
