1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety during repairs.
Ensure the vehicle is on a level surface and securely supported if lifting is required.

2. Check Transmission Fluid

Remove the transmission dipstick (if applicable) to check fluid level.
If fluid is low or burnt, drain the transmission fluid and replace with manufacturer-recommended fluid.
Torque the drain and fill plugs to the manufacturer specifications.

3. Inspect Gear Shift Assembly

Remove the gear shift cover and any surrounding trim pieces.
Inspect the gear selector linkage for damage or disconnection.
Reconnect or replace any damaged components as necessary.

4. Test and Replace Brake Switch

Locate the brake light switch near the brake pedal.
Use a multimeter to test the switch for continuity; replace if faulty.
Reconnect the battery and test the brake lights to ensure they function properly.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any error codes and check for reoccurrence after driving.
