Saturn Trouble Codes

Code Retrieval Prodecure

See GM trouble code retrieval procedure to retrieve the trouble codes.

The Check Engine light will light when the ECU stores a trouble code.

Counting the Flashes

To retrieve trouble codes, turn the ignition key to the “on” position with the engine OFF.

The Check engine light will flash many short blinks. The total number of blinks equals the code number. For example, flash,pause, flash,flash = code 12.If more than one code is stored, the Check engine light will flash the codes in sequence (lowest to highest) with a pause between each code. The codes will repeat until the key is turned to the OFF position.

1996-up models:

Are OBD2 systems and require a scanner to access the codes.
