Reading and Clearing Diagnostic Trouble Codes

Clearing Transmission Diagnostic Trouble Codes

Important: Disconnecting the battery terminals or the TCM connectors will NOT clear a transmission-related DTC. A transmission-related DTC may only be cleared using a scan tool.

1. Install a scan tool.
2. Turn ON the ignition with the engine OFF.

Important: Before clearing the DTC, use the scan tool in order to record the ECM Freeze Frame and the TCM Failure Records. Using the Clear Into function erases the Freeze Frame and Failure Records from the ECM and TCM.

3. Record the DTC Freeze Frame and Failure Records.
4. Clear the DTC.
5. Turn OFF the ignition and wait 10 seconds.
6. Turn ON the ignition and wait 5 seconds. The DTC(s) should be cleared.
