Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion on battery terminals using a wire brush.
- Tighten the battery terminal connections.
Replace Battery (if necessary):
- Remove the negative terminal first, then the positive terminal.
- Unscrew and remove the battery hold-down bracket.
- Lift out the old battery and replace it with a new one (ensure correct size and specifications).
- Reinstall the hold-down bracket and connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection and Replacement

Inspect Starter:
- Locate the starter under the vehicle.
- Check for loose connections on the starter motor terminals.
Replace Starter (if necessary):
- Disconnect the battery before starting.
- Remove the starter motor bolts using a socket set.
- Disconnect the wiring harness from the starter.
