Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, socket set, and safety gloves.
Ensure the vehicle is in a safe location with the parking brake engaged.
Disconnect the negative terminal of the 12V battery for safety.

2. Battery Inspection

Check Battery Voltage:
- Reconnect the multimeter to the battery terminals and check voltage.
- If below 12.4 volts, proceed to jump-start or replace the battery.
Clean Terminals:
- Disconnect the battery terminals (negative first).
- Clean any corrosion from the terminals and cable ends using a wire brush.
- Reconnect the battery terminals, ensuring they are tight.

3. Key Fob Check

Test Key Fob:
- Replace the key fob battery if necessary.
- Attempt to start the vehicle with the key fob in proximity to the start button.

4. Starter Motor Testing

Bypass Starter Circuit:
- Use a jumper wire to connect the starter solenoid terminal to the battery positive terminal.
- If the starter engages, the ignition switch may be faulty; otherwise, replace the starter motor.

5. Final Connection

Reconnect the negative terminal of the battery once all checks and repairs are complete.
Ensure all connections are secure.
