Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect and Replace Brake Light Switch

Tools Required: Socket set, multimeter
Locate the brake light switch, typically found near the brake pedal.
Use a multimeter to test the switch for continuity when the brake pedal is pressed.
If faulty, remove the old switch by unscrewing it and disconnect the wiring harness.
Install the new brake light switch by reversing the removal steps and ensure it is securely connected.

3. Examine Shifter Assembly

Tools Required: Screwdriver set
Remove any panels necessary to access the shifter assembly.
Inspect for physical obstructions or damage within the shifter mechanism.
If damaged, replace the shifter assembly with a new unit.
Reassemble the panels and ensure the shifter moves freely.

4. Check Transmission Control Module (TCM)

Tools Required: OBD-II scanner
Reconnect the battery and use the OBD-II scanner to check for TCM-related error codes.
If codes indicate a fault, reprogram or replace the TCM as necessary, following the manufacturer's specific instructions.

5. Final Assembly and Testing

Reassemble any components removed for access.
Ensure all connectors are secure.
Reconnect the battery and conduct a test drive to confirm the vehicle shifts out of park properly.
