Service Codes: Notes
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 1993 Mercury Tracer, 1993 Mercury Topaz, 1993 Mercury Sable, 1993 Mercury Grand Marquis, and 1993 Mercury Cougar. However, it is still accessible from the selected car via links, so may be relevant.
All models use 3-digit codes. When CIRCUIT TEST procedures apply to both 2-digit codes and 3-digit codes, the applicable codes will be separated by a diagonal mark (example: Code 31/327).
During QUICK TEST, 3 types of service codes are retrieved: KOEO, KOER and Continuous Memory codes. See QUICK TEST for self-test procedures. Codes may be cleared from PCM memory after they have been recorded or repaired. See CLEARING CODES.
