Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery
- Remove the battery terminals (negative first, then positive).
- Clean terminals with a wire brush to remove corrosion.
Test Battery
- Connect a multimeter to the battery terminals to check voltage.
- If voltage is low, charge the battery or replace it if it can't hold a charge.

3. Starter Inspection and Replacement

Remove Starter
- Disconnect the negative battery terminal.
- Locate and unbolt the starter (typically located near the transmission).
- Detach electrical connectors from the starter.
Inspect Starter
- Test the starter using a bench test or replace it if necessary.

4. Reassemble and Connect

Reinstall the starter and secure it with bolts to the specified torque (usually around 15-30 lb-ft, check your service manual).
Reconnect electrical connectors and battery terminals (positive first, then negative).
