Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and screwdriver.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical shorts.

2. Inspect the Brake Switch

Locate the brake switch, usually found above the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
- If there is no continuity, replace the brake switch.

3. Check the Gear Selector Assembly

Remove the center console cover to access the gear selector assembly.
Inspect the wiring and connectors for loose connections or damage.
If necessary, replace the gear selector assembly.

4. Test the Interlock System

With the brake pedal pressed, manually override the interlock mechanism (usually a small slot on the gear shift).
If the vehicle shifts out of park, the interlock system may need adjustment or replacement.

5. Refill Transmission Fluid (if low)

Locate the transmission dipstick and pull it out.
Check fluid level; if low, add manufacturer-recommended transmission fluid.
Inspect fluid for contamination; if dirty, consider a transmission flush.

6. Reassemble and Test

Reinstall the center console and reconnect the battery.
Start the vehicle and attempt to shift from park.
