To reset the Powertrain Control Module (PCM), you can disconnect the vehicle's battery by removing the negative terminal for about 15-30 minutes. This allows the PCM to clear its memory and reset. After reconnecting the battery, turn the ignition to the "ON" position (without starting the engine) for a few moments, then start the vehicle. If needed, you can also use an OBD-II scanner to perform a reset.
