4. Replace Brake Pedal Switch

Tools Required: Screwdriver set, socket set.
Steps:
1. Locate the brake pedal switch, usually mounted near the top of the brake pedal.
2. Disconnect the wiring harness from the switch.
3. Remove the old switch and install the new switch, ensuring it is properly aligned.
4. Reconnect the wiring harness and test for proper functioning.

5. Transmission Control Module (TCM) Reset

Tools Required: OBD-II scanner.
Steps:
1. Reconnect the battery after all repairs are made.
2. Use the OBD-II scanner to reset any fault codes related to the TCM.
3. Perform a test drive to ensure the transmission engages properly into reverse.
