Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Adjust Brake Light Switch

Locate the brake light switch, usually near the brake pedal.
Check the switch for proper operation by pressing the brake pedal; the switch should engage and disengage.
If misaligned, adjust the switch position and verify brake lights function correctly.

3. Examine Transmission Shift Cable

Remove the center console cover to access the shift cable.
Inspect the cable for signs of fraying or damage.
If damaged, loosen the retaining bolts, disconnect the cable from the transmission, and replace it with a new one.

4. Check Shifter Assembly

Remove the shifter assembly from the vehicle.
Inspect for wear, cracks, or broken components.
If necessary, replace any damaged parts and reassemble the shifter.

5. Test Park/Neutral Position Switch

Locate the park/neutral position switch on the transmission.
Use a multimeter to test the continuity of the switch in both 'Park' and 'Neutral' positions.
Replace the switch if it fails the continuity test.

6. Reassemble and Connect Battery

Reinstall any components removed during the process.
Reconnect the battery and ensure all connections are secure.
