Solution

1. Preparation

Gather tools: Socket set, multimeter, OBD-II scanner, screwdriver, and a flashlight.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Inspect Brake Light Switch

Step 1: Locate the brake light switch, usually mounted above the brake pedal.
Step 2: Disconnect the wiring harness from the switch.
Step 3: Test the switch using a multimeter; ensure it closes when the brake pedal is pressed.
Step 4: If faulty, replace the brake light switch with a new one.

3. Check Transmission Fluid

Step 1: Locate the transmission dipstick (if applicable).
Step 2: Remove the dipstick, wipe it clean, and reinsert it.
Step 3: Check the fluid level; it should be within the marked range.
Step 4: Inspect the fluid for burnt smell or dark color; if contaminated, change the transmission fluid.

4. Test Shift Interlock Solenoid

Step 1: Locate the shift interlock solenoid (consult the service manual for exact location).
Step 2: Disconnect the electrical connector from the solenoid.
Step 3: Use a multimeter to check for continuity; replace if there's no continuity when the brake pedal is pressed.

5. Manual Release

Step 1: Locate the manual release lever near the gear shift (usually covered by a plastic cap).
Step 2: Remove the cap if present.
Step 3: Use a screwdriver to push the lever down and attempt to shift into gear.
Step 4: If this works, inspect the linkage for any obstructions or wear.
