Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect Brake Light Circuit

Tools Required: Multimeter, screwdriver
Sub-steps:
1. Remove the fuse box cover under the dashboard.
2. Use a multimeter to test the brake light fuse; replace if blown.
3. If the fuse is intact, follow the brake light switch wire to ensure no breaks or shorts are present.

3. Check Brake Light Switch

Tools Required: Screwdriver
Sub-steps:
1. Locate the brake light switch on the brake pedal assembly.
2. Remove the switch and test it with a multimeter for continuity when the pedal is pressed.
3. Replace the brake light switch if it does not function properly.

4. Inspect Shift Interlock Solenoid

Tools Required: Socket set, multimeter
Sub-steps:
1. Locate the shift interlock solenoid, typically near the gear shift assembly.
2. Disconnect the wiring harness from the solenoid.
3. Test the solenoid with a multimeter. If it does not activate, replace it.

5. Clear Obstructions and Reassemble

Tools Required: None
Sub-steps:
1. Inspect the gear shift mechanism for any debris or obstruction.
2. Remove any found debris and ensure smooth operation of the shift lever.
3. Reassemble any components removed during inspection.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the gear shift is now operable.
