Quick Test 4.0 - Continuous Memory Codes

Continuous DTCs are concerns which were detected during normal vehicle operation. These DTCs are retained for 40 warm-up cycles.

Some special considerations for Key On, Engine Off Quick Test include the following:
- The cause of some continuous DTCs may have been eliminated if KOEO and/or KOER DTCs were repaired. Always retest and repair any DTCs that still remain.
- If DTCs are present, go to the On-Board Diagnostic Trouble Code Description Chart for repair information. Erase the DTC, perform the Transaxle Drive Cycle Test, and repeat all Quick Test procedures after completing repairs on the DTCs.
- If the continuous test passes and a concern is still present, refer to the Diagnosis by Symptom Chart and TSBs for concern diagnosis. Symptom Related Diagnostic Procedures
