Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Inspect the battery:
1. Clean any corrosion from battery terminals using a wire brush.
2. Reconnect the terminals securely.
Replace if necessary:
1. Remove the battery hold-down bracket with a socket set.
2. Carefully lift the battery out of the tray and replace it with a new one (ensure it matches vehicle specifications).
3. Reinstall the hold-down bracket and secure it.
4. Reconnect the negative terminal first, then the positive terminal.

3. Starter Motor Testing and Replacement

Testing:
1. Locate the starter motor (typically near the transmission).
2. Connect a multimeter to the starter motor terminals while someone else turns the ignition to the start position.
3. If there is no voltage at the starter motor, check wiring and connections.
Replacement (if necessary):
1. Disconnect wiring harness and battery cables from the starter.
2. Remove the starter mounting bolts using a socket set.
3. Carefully pull the starter out and replace it with a new unit.
4. Reinstall the starter, reconnect the wiring, and secure battery cables.
