Determining Continuous Memory Codes To Be Tested

The cause of some of the continuous memory codes may have been eliminated during either KEY ON/ENGINE OFF (KOEO) or KEY ON/ENGINE RUNNING (KOER) SELF-TEST repairs. Diagnose only those continuous memory codes for which a similar code has not been previously serviced. Once this has been determined, go to KOEO & KOER SELF-TEST procedures.
