Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent any electrical shocks.

2. Check Brake Fluid Level

Locate the brake fluid reservoir (usually near the driver's side).
Remove the cap and check if the fluid is at the "Full" mark.
If low, add the appropriate brake fluid (DOT 3 or DOT 4) until it reaches the correct level.

3. Inspect Brake Light Switch

Locate the brake light switch above the brake pedal.
Disconnect the electrical connector from the switch.
Use a multimeter to test if the switch operates correctly (should show continuity when the pedal is pressed).
If faulty, replace the brake light switch.

4. Examine Shift Interlock Solenoid

Locate the shift interlock solenoid, typically near the gear shifter assembly.
Disconnect the wiring harness from the solenoid.
Use a multimeter to check for power supply to the solenoid when the brake pedal is pressed.
If there’s no power, trace the wiring back to the brake light switch or fuse.
If powered and still not functioning, replace the solenoid.

5. Inspect Gear Shift Mechanism

Remove the gear shift cover to access the shifter mechanism.
Check for any debris or obstructions that could be preventing movement.
Inspect the mechanism for wear or damage and lubricate any moving parts if necessary.
Reassemble the gear shift cover.

6. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and check if the gear shifter can now be moved out of the "Park" position.
