NOTE: 96 & later are OBD2 systems and require a scanner. For an OBD2 code list, please see our Saturn code list or the appropriate generic list.

Saturn: Accessing Diagnostic Trouble Codes

• Please see our GM trouble code retrieval procedure page for additional information applicable to retrieving Saturn trouble codes.

Before 1996 (Without OBD2 Scan Tool)

• 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.
