Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from the terminals and connectors using a wire brush.
- Reconnect the terminals securely.
Replace Battery (if needed):
- If the battery voltage is low (below 12.4 volts), replace it.
- Use a compatible battery (check the owner's manual for specifications).
- Install the new battery (positive terminal first, then negative).

3. Starter Motor Inspection and Replacement

Inspect Starter Motor:
- Locate the starter motor (usually near the transmission).
- Check for loose connections or damage to wiring.
Replace Starter Motor (if necessary):
- Disconnect the battery again for safety.
- Remove the bolts securing the starter motor.
- Disconnect the electrical connectors.
- Install the new starter motor in reverse order of removal, ensuring all connections are secure.
