ECU Fault Codes

ECU Fault Codes

Long Flash - 0.6 seconds on (the first digit)

Short Flash - 0.3 seconds on (the second digit)

Long Gap - 2.1 seconds off (used between codes)

Short Gap - 0.9 seconds off (used between digits)

There are two digits in each code. Count the long flashes, then the short flashes (only count how many times the light is ON) and you'll have a 2 digit code. These codes are covered in the service manual.
