Check for any obstructions or damage.
If the mechanism is faulty, replace it with a new part.

5. Test Wiring and Connectors

Visually inspect all wiring and connectors related to the gear selector and brake pedal switch.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors.

6. Battery Voltage Check

Use a multimeter to measure the battery voltage.
Ensure it is above 12.4 volts. If not, fully charge or replace the battery.
