Quick Test 4.0 - Continuous Memory Codes

Continuous DTCs are concerns which were detected during normal vehicle operation. These codes are retained for 40 warm-up cycles.
- The cause of some continuous DTCs may have been eliminated if KOEO and/or KOER DTCs were serviced. Always retest and service any DTCs that still remain.
- Erase DTC, perform the Transmission Drive Cycle Test and repeat all Quick Test procedures after completing service on the DTCs.
- If the Continuous tests passes and a concern is still present, refer to the Diagnosis by Symptom charts and TSBs for concern diagnosis.
