Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Clean Battery Terminals
- Use a wire brush to clean terminals and remove corrosion.
- Reconnect terminals securely.
Test and Replace Battery
- If the battery voltage is below 12.4 volts, replace the battery.
- Ensure the new battery is fully charged before installation.
- Reconnect the negative terminal.

3. Starter Motor Inspection

Remove Starter Motor
- Disconnect battery (negative terminal).
- Raise the vehicle and secure it on jack stands.
- Remove any undercarriage covers if necessary.
- Disconnect the wiring harness and the mounting bolts from the starter.
Test Starter Motor
- Bench test the starter motor using jumper cables to ensure it operates correctly.
- If faulty, replace with a new starter motor.

4. Check and Replace Fuses

Locate the fuse box and identify the fuses associated with the starter system.
Replace any blown fuses with ones of the same amperage.

5. Reassemble

Reinstall the starter motor and secure it with bolts.
Reconnect all wiring and ensure connections are tight.
Reconnect the negative battery terminal.
