Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe working area, and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Inspect and Clean Battery Connections

Remove the positive and negative battery terminals.
Clean the terminals and battery posts with a wire brush to remove any corrosion.
Reattach the battery terminals securely.

3. Test and Replace the Battery (if necessary)

Reconnect the negative battery terminal.
Use a multimeter to check the battery voltage; replace the battery if voltage is below 12.4 volts.
If replacing, ensure the new battery matches the vehicle specifications.

4. Check Starter Motor and Relay

Locate the starter motor, usually found near the transmission.
Inspect the starter motor wiring for any signs of damage.
Remove the starter relay and test it; replace if faulty.

5. Test Starter Functionality

Reconnect the negative battery terminal.
Use a remote starter switch or jump the starter solenoid terminals to test if the starter engages.
If the starter does not engage, replace the starter motor.
