Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver, torx bit set.
Park the vehicle on a flat surface and set the parking brake.
Disconnect the battery negative terminal to ensure safety while working on electrical components.

2. Inspect and Repair the Brake Switch

Sub-steps:
1. Locate the brake switch, typically found near the brake pedal assembly.
2. Disconnect the electrical connector from the brake switch.
3. Test the brake switch using a multimeter; it should show continuity when pressed.
4. If faulty, replace the brake switch with a new component.
5. Reconnect the electrical connector.

3. Check Gear Selector Assembly

Sub-steps:
1. Remove any trim panels around the gear selector using a flathead screwdriver or trim removal tool.
2. Unscrew and remove the gear selector assembly from the console.
3. Inspect the mechanism for obstructions or damage.
4. Clean any debris and lubricate moving parts if necessary.
5. Reinstall the gear selector assembly and trim panels securely.

4. Check Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick (if applicable) or access the fill plug.
2. Check the fluid level; add fluid if low, using the manufacturer-recommended transmission fluid type.
3. Inspect fluid quality; if it appears burnt or contaminated, consider a fluid change.

5. Reconnect Battery

Reconnect the negative terminal of the battery.
Clear any error codes using the OBD-II scanner and perform a function test.
