Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect Brake Light Switch

Locate the brake light switch, usually found above the brake pedal.
Disconnect the electrical connector from the switch.
Use a multimeter to test the switch for continuity when the brake pedal is pressed.
If faulty, replace with a new brake light switch.

3. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check fluid level.
If low, add the appropriate type of transmission fluid (consult the owner's manual for specifications).
Inspect fluid condition; if burnt or discolored, consider a fluid change.

4. Test Shift Interlock Solenoid

Locate the shift interlock solenoid, typically part of the shifter assembly.
Disconnect the wiring harness from the solenoid.
Test the solenoid using a multimeter to ensure it receives power when the brake pedal is pressed.
Replace the solenoid if it doesn't engage properly.

5. Inspect Gear Shift Mechanism

Remove the center console cover to access the gear shift mechanism.
Check for any obstructions or damage within the mechanism.
Clean any debris and lubricate moving parts if necessary.
Reassemble the console after inspection.
