Clearing Codes

NOTE: DO NOT disconnect vehicle battery to clear codes. This will erase stored operating information from Keep-Alive Memory (KAM). If KAM has been cleared, drive vehicle 10 miles or more to allow PCM to relearn operating conditions and driving style of vehicle. Driveability may be affected during relearning cycle.

To clear codes from PCM memory, start KOEO SELF-TEST. When service codes appear on test equipment or CHECK ENGINE light, disconnect jumper wire from Self-Test Input (STI) connector. If using Super Star II tester, Unlatch center button. This procedure erases Continuous Memory Codes from PCM memory. If problem has not been corrected and fault is still present, hard code will be reset in PCM memory.
