Solution

1. Preparation

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

2. Inspect and Test the Brake Light Switch

Sub-steps:
1. Locate the brake light switch, typically found near the brake pedal.
2. Disconnect the electrical connector from the brake light switch.
3. Use a multimeter to check for continuity; press the brake pedal to see if the switch closes.
4. If there is no continuity, replace the brake light switch.

3. Test the Shift Interlock Solenoid

Sub-steps:
1. Locate the shift interlock solenoid, usually mounted near the transmission or the gear shift assembly.
2. Disconnect the electrical connector from the solenoid.
3. Use a multimeter to test for power at the connector while pressing the brake pedal.
4. If power is present and the solenoid does not activate, replace the shift interlock solenoid.

4. Inspect the Gear Shift Lever Assembly

Sub-steps:
1. Remove the center console cover to access the gear shift lever assembly.
2. Inspect for any foreign objects or debris that may be obstructing the lever's movement.
3. Check for any broken or damaged components within the assembly.
4. Reassemble the console if no issues are found.
