Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather all necessary tools and parts.
Disconnect the battery to avoid any electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick, pull it out again, and check fluid level; add the specified ATF if low.
If the fluid is dark or has a burnt smell, a fluid change may be necessary.

3. Inspect Transmission Linkage

Locate the transmission linkage and visually inspect it for any disconnections or damage.
If necessary, adjust or replace the linkage components as per manufacturer specifications.

4. Test Brake Switch

Locate the brake switch, typically found near the brake pedal.
Use a multimeter to check for continuity when the pedal is pressed; replace the switch if it is faulty.

5. Reconnect Battery

Reconnect the battery terminals securely.
Ensure that all connections are clean and free of corrosion.
