The following list shows possible ECU fault codes, causes and recommended solutions. If a fault is displayed that is not listed, contact your dealer for further advice. You can use enter the code into the search bar to narrow your results.
Fault codes are displayed in iVTS in the ECU Status runtime values. They may also be displayed on a Check Engine Light or a digital dashboard display.
Fault codes can be cleared by selecting Clear Fault Codes in the ECU Controls drop down menu.
Please make sure to check all iVTS runtime values for real time information on ECU parameters.
