Check Engine Light Codes (CEL)

 

To identify an existing fault, you will need to follow the following procedure. Please also note that the ECU light flashes to indicate the error code, the slow flashes which come first are the tens digits. The fast flashes that come second are the single digits. For example, an error code of 13 will be one slow flash and 3 quick flashes straight after the first flash, then their will be a short break and it will flash the sequence again.
