Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Brake Light Switch

Locate the brake light switch, usually mounted on the brake pedal assembly.
Disconnect the wiring harness from the switch.
Remove the switch by unbolting it from its mount.
Install the new brake light switch by reversing the removal steps.
Reconnect the wiring harness to the switch.

3. Inspect Shift Interlock Mechanism

Remove the center console trim to access the shifter assembly.
Check for any debris or blockage in the shift interlock mechanism.
Manually operate the interlock lever to ensure it moves freely.
Lubricate moving parts if necessary and reassemble the console.

4. Check Transmission Fluid Level

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the appropriate type of transmission fluid (consult the owner’s manual).
If the fluid is dark or smells burnt, consider a transmission fluid change.

5. Test Electrical Connections

Inspect all wiring and connectors to the shifter for damage or corrosion.
Use a multimeter to check for continuity in the electrical connections.
Repair or replace any damaged wiring or connectors.
