How To: Check Fault Codes

Checking Fault Codes

To obtain fault codes using the MIL (Check Engine Light):

1. Cycle ignition key to ON, OFF, ON, OFF, ON within 5 second (do not actually crank engine!!)

2. Count the number of times the MIL on the instrument panel flashes on and off. The number of flashes represents the trouble code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses seperate the individual two digit trouble code.

Example: Lamp flashes 4 times, pauses, then flashes 6 more times. This is an indicates a DTC of 46.

3. Lamp will always flash 55 at the end of the test. This signals the end of the test.
