Continuous Memory Codes

These codes are issued as a result of information stored during CONTINUOUS SELF-TEST. These codes are displayed during a KOEO SELF-TEST after the separator pulse code. These codes should be used for diagnosis, ONLY when KOEO and ENGINE RUNNING SELF-TESTS result in code 11 and all QUICK TEST steps have been successfully completed.

NOTE: If engine will not start, starts but stalls, idles rough or runs rough, go through KEY ON/ENGINE OFF (KOEO) SELF-TEST  . If any of the above conditions are still present after a code 11 in the KOEO SELF-TEST, go to TEST A1  for a no start condition. If engine stalls or runs rough, go to DIAGNOSIS BY SYMPTOM TEST  charts.

NOTE: Correct test results for system are dependent on the correct operation of several related non-EEC components and systems. It may be necessary to correct faults in these areas before EEC-IV will pass QUICK TEST. Verify that vehicle has been properly prepared. See PREPARATION  and EQUIPMENT HOOK-UP  . Turn ignition on to start SELF-TEST. DO NOT  depress throttle during test. Observe and record all service codes.
