Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety during repairs.

2. Inspect Brake Light Switch

Locate the brake light switch, typically mounted above the brake pedal.
Check the switch for proper operation:
- Use a multimeter to measure continuity; replace the switch if faulty.
Adjust the switch position if it's misaligned to ensure it activates properly.

3. Check Fuses

Locate the fuse box in the cabin and under the hood.
Identify the fuses related to the transmission and shift interlock system.
Inspect each fuse for continuity and replace any that are blown with a fuse of the same amperage.

4. Examine Shift Interlock Solenoid

Access the shift interlock solenoid, usually located near the gear shifter.
Disconnect the wiring harness and test the solenoid with a multimeter to check for proper voltage.
Replace the solenoid if it fails the test.

5. Reassemble and Test

Reconnect the battery and ensure all components are secured.
Start the vehicle and attempt to shift out of Park while pressing the brake pedal.
Check for normal operation; if shifting is successful, proceed to verification.
