List Of Fault Codes for the S15

ECU codes show up on the check engine light in the combination meter. They way they read is by counting the number of flashes ( as well as the speed of the flashes)

For example, an ECU showing no recorded faults will display code 55. The first digit is shown as 5 long flashes (tens) followed by a pause and followed by the second digit - 5 short flashes. Thus Code 55.
