Making Changes To The TCM Calibration
If the TCM does not complete the reflash after two consecutive attempts, follow the instructions listed below
- If the TCM reprogramming aborts during the procedure: Reprogram the TCM again. After the TCM reprogramming is successfully completed, clear the continuous DTCs in the PCM and the TCM.
- If the TCM reprogramming aborts immediately after the start: Turn the key OFF. Disconnect the PCM body/cowl connector, and leave it disconnected. Turn the key ON. Start the TCM reprogramming. After the TCM reprogramming is successfully completed, turn the key OFF and connect the PCM body/cowl connector. Clear any PCM and TCM DTCs that may have been stored during reprogramming.
