Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools required:
- Multimeter
- Socket set
- Screwdriver set
- OBD-II scanner
Ensure the vehicle is in a safe location with the parking brake engaged.

2. Battery Inspection

Disconnect the negative terminal of the battery to prevent electrical shorts.
Clean any corrosion from the battery terminals using a wire brush.
Reconnect the battery terminals securely after cleaning.

3. Starter Motor Testing

Locate the starter motor (typically near the engine block).
Disconnect the wiring harness from the starter.
Use a multimeter to check for voltage at the starter terminal when the ignition is turned on.
If voltage is present but the starter does not engage, proceed to remove the starter from the vehicle.

4. Starter Replacement (if necessary)

Remove the starter motor by unscrewing the mounting bolts.
Replace with a new or refurbished starter motor, ensuring proper alignment.
Torque the mounting bolts to the manufacturer’s specifications (typically around 15-25 ft-lbs).
Reconnect the wiring harness to the starter.

5. Final Check

Reconnect the negative battery terminal.
Start the vehicle to confirm the repair was successful.
