Reconnect the linkage securely.

4. Check and Replace Brake Switch (if necessary)

Tools Required: Screwdriver, multimeter
Test the brake switch with a multimeter to ensure it operates correctly.
If faulty, remove the old brake switch by unscrewing it from its mount.
Install a new brake switch and adjust it according to specifications.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and attempt to shift into reverse to verify that the issue has been resolved.
