3. Install the new brake light switch and reconnect the electrical connector.

5. Inspect Transmission Control Module (TCM)

Tools Required: OBD-II scanner, multimeter.
Sub-steps:
1. Use the OBD-II scanner to check for stored fault codes in the TCM.
2. If faults are present, follow up with necessary repairs or replacement of the TCM.
3. Check the TCM wiring harness for any signs of damage or corrosion.
