Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver, and a flashlight.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Check Brake Light Switch

Locate the brake light switch, typically found above the brake pedal.
Sub-steps:
1. Disconnect the electrical connector from the brake light switch.
2. Use a multimeter to test for continuity when the brake pedal is pressed.
3. If no continuity is found, replace the brake light switch.
4. Reconnect the switch and check that the brake lights function properly.

3. Inspect Fuses

Access the fuse box, usually located under the dashboard or in the engine compartment.
Sub-steps:
1. Identify the fuse for the shift interlock system (refer to the owner's manual).
2. Remove the fuse and check for continuity using a multimeter.
3. If blown, replace it with a fuse of the same amperage.

4. Check Shift Interlock Solenoid

Locate the shift interlock solenoid, typically near the gear shifter assembly.
Sub-steps:
1. Inspect the wiring and connectors for damage or corrosion.
2. Use a multimeter to test the solenoid for proper voltage when the brake pedal is pressed.
3. If the solenoid is faulty, remove it and replace it with a new unit.

5. Inspect Gear Shifter Linkage

Visually inspect the gear shifter assembly and linkage.
Sub-steps:
1. Ensure there are no obstructions preventing movement.
2. If any parts are damaged, replace them accordingly.
3. Lubricate the linkage if it appears sticky.
