Quick Test 4.0 - Continuous Memory Codes

Continuous Diagnostic Trouble Codes (DTCs) are concerns which were detected during normal vehicle operation. These codes are retained for 40 warm-up cycles.

Some special considerations for continuous testing include the following:
- 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.
- If DTCs are present, go to the On-Board DTC Description Chart for service information. Erase DTC, perform the Transaxle Drive Cycle Test and repeat all Quick Test procedures after completing service on the DTCs.
- If the continuous test passes (P1111) and a concern is still present, refer to the Diagnosis by Symptom charts and Technical Service Bulletins (TSBs) for concern diagnosis.

PERFORMING CONTINUOUS DTC TESTS
- Select "Vehicle and Engine Selection" menu.
- Select year, engine, model with the appropriate qualifier if needed - for example, 49-State/California.
- Select "Diagnostic Data Link" menu.
- Select "Output Test Mode" menu.
- Select "Retrieve Continuous Codes" menu.
- Follow operating instructions from the NGS menu screen.
- Record all Diagnostic Trouble Codes (DTCs) displayed.
- Perform Transaxle Drive Cycle Test.
- Rerun Continuous DTC Test, if DTCs have returned, and services as required. Road test and rerun all DTC test procedures.
