Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and new key fob battery if necessary.
Ensure the vehicle is in a safe working environment and parked on a level surface.

2. Replace Key Fob Battery

Open the key fob using a small screwdriver to pry open the casing.
Remove the old battery and insert a new one, ensuring correct polarity (+/-).
Reassemble the key fob casing securely.

3. Check and Adjust Brake Switch

Locate the brake switch under the dashboard near the brake pedal.
Ensure that the switch is properly aligned and that the pedal pushes it fully when pressed.
If the switch is faulty, disconnect the wiring harness and replace the switch with a new one, ensuring it's securely mounted.

4. Inspect Remote Start System Wiring

Open the hood and locate the remote start module (if installed).
Visually inspect all connections and wiring for signs of wear, corrosion, or loose connections.
Secure any loose wires and replace any damaged components.
