DTCM VERIFICATION TEST
PERFORM DTCM VERIFICATION TEST

CAUTION: Before removing the DTCM harness connectors, clean the connectors and locking cam area of dirt and debris. Failure to do so can result in the connector being jammed or damage to the locking cams on the harness connector or module. Do not force the assist arm when releasing or installing the harness connector.

NOTE: If the Powertrain Control Module (PCM) or Totally Integrated Power Module (TIPM) was replaced, refer to the proper programming procedures.

1. Disconnect all jumper wires and reconnect all previously disconnected components and connectors.
2. Make sure that all accessories are turned off.
3. Make sure that the battery is fully charged.
4. With the scan tool, record and erase all DTC(s) from the DTCM.
5. Start and run the engine for two minutes while operating all functions of the system that caused the original concern.

NOTE: When a Stabilizer System DTC diagnostic is complete and all repairs have been made, running the Stabilizer Motor System Test and/or LED System Test can also provide verification that the DTC has been repaired and the system is operating normally.

6. Turn the ignition off, wait five seconds, then turn the ignition on. Using the scan tool, read DTC(s) from the DTCM.

Are any DTCM DTC(s) present or is the original condition still present?

Yes

- The repair is not complete. Perform the appropriate diagnostic procedure for the DTC or symptom that is still present.

No

- The repair is complete.
