Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Check Battery Terminals
- Remove the positive (+) and negative (-) battery cables.
- Clean any corrosion from the terminals and battery posts using a wire brush.
- Reconnect the terminals securely.
Replace Battery if Necessary
- If the battery voltage is low or fails a load test, replace it.
- Use a compatible battery with specifications matching the original (e.g., Group Size 35).
- Install the new battery, connecting the positive terminal first followed by the negative.

3. Starter Motor Inspection and Replacement

Check Starter Motor
- Locate the starter motor, usually mounted near the transmission bell housing.
- Disconnect the wiring harness from the starter.
- Use a multimeter to check for voltage at the starter solenoid while attempting to start the vehicle.
Replace Starter Motor if Necessary
- If no voltage is present, check the ignition switch and wiring.
- If voltage is present but the starter doesn't engage, remove the starter using a socket set.
- Install the new starter motor, ensuring all connections are secure and torqued to manufacturer specifications.
