Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, replacement fuse (if needed).
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Brake Light Switch Inspection

Locate the brake light switch, usually found near the brake pedal.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity when the brake pedal is pressed.
- If there is no continuity, replace the brake light switch.

3. Shift Interlock Solenoid Check

Access the shift interlock solenoid, which is typically located near the gear shifter assembly.
Disconnect the wiring harness from the solenoid.
Test the solenoid with a multimeter to check for proper resistance values (usually specified in the service manual).
If the solenoid is faulty, replace it.

4. Fuse Inspection

Locate the fuse box (refer to the owner’s manual for location).
Identify the fuse related to the shift interlock system.
Pull the fuse out and inspect it visually; replace it if it appears blown.

5. Reassembly and Reconnect Battery

Reconnect any wiring harnesses that were disconnected.
Ensure all components are securely in place.
Reconnect the negative battery terminal.
