Making Changes To The TCM Calibration

If the TCM does not complete the reflash after two consecutive attempts, follow the instructions listed below:

1. 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.
2. If the TCM reprogramming aborts immediately after the start:

• Turn the ignition OFF.
• Disconnect the PCM body/cowl connector, and leave it disconnected.
• Turn the ignition ON.
• Start the TCM reprogramming.
• After the TCM reprogramming is successfully completed, turn the ignition OFF and connect the PCM body/cowl connector.
• Clear any PCM and TCM DTCs that may have been stored during reprogramming.
