Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, jumper cables, and a clean rag.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Battery Inspection and Replacement

Check Battery Condition
- Clean battery terminals using a wire brush and a mixture of baking soda and water.
- Reconnect terminals securely.
If Battery is Faulty
- Use a multimeter to test the voltage; replace the battery if voltage is below 12.4 volts.
- Remove the old battery: unscrew the hold-down bracket, disconnect the positive terminal first, then the negative.
- Install the new battery: connect the negative terminal first, then the positive, and secure the hold-down bracket.

3. Starter Inspection and Replacement

Test Starter
- If the battery is good, check the starter connections.
- Remove the starter from the vehicle (disconnect wiring harness and remove mounting bolts).
If Starter is Faulty
- Replace with a new starter: install the new starter in the reverse order of removal, ensuring all connections are tight and secure.
- Torque the mounting bolts to the manufacturer's specifications (consult service manual for values).

4. Relay and Fuse Check

Inspect Starter Relay
- Remove the starter relay from the fuse box and test for continuity using a multimeter.
- Replace relay if it’s defective.
Check Fuses
- Replace any blown fuses found during the inspection, ensuring the new fuses match the specified amperage.
