Solution

1. Preparation

Ensure the vehicle is on a flat surface and the parking brake is engaged.
Gather tools and parts required for the repair.

2. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
If the fluid is low, top it off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Recheck the shifting mechanism after adding fluid.

3. Inspect Brake Light Switch

Disconnect the negative battery terminal.
Locate the brake light switch, usually mounted near the brake pedal.
Test the switch with a multimeter to ensure it is functioning correctly. If it’s defective, replace it.
Reconnect the battery terminal after the switch is verified or replaced.

4. Test Shift Interlock Solenoid

With the brake pedal depressed, check for power to the shift interlock solenoid using a multimeter.
If there is no power, trace the wiring back to the brake light switch and inspect for breaks or shorts.
If the solenoid is faulty, replace it according to the manufacturer’s instructions.

5. Inspect Gear Shift Linkage

Remove the center console cover to access the gear shift linkage.
Inspect for any obstructions or damage that could prevent shifting.
Realign or replace any damaged components as necessary.
