Solution

1. Preparation

Gather tools: socket set, multimeter, battery terminal cleaner, and safety gloves.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Clean the battery terminals using a battery terminal cleaner.
Tighten the connections to ensure they are secure.
Reconnect the negative terminal.

3. Battery Replacement (if necessary)

If the battery voltage is low or it fails the load test:
1. Remove the battery: Disconnect the negative terminal first, followed by the positive terminal.
2. Unbolt the battery hold-down bracket and lift the battery out.
3. Install a new battery by placing it in the tray, securing the hold-down bracket, and connecting the positive terminal first, then the negative terminal.

4. Starter Inspection and Replacement

If the battery is functional:
1. Locate the starter motor, typically near the transmission bell housing.
2. Disconnect the electrical connectors from the starter.
3. Unbolt the starter motor using the socket set.
4. Install a new starter motor by reversing the steps: position the starter, bolt it in place, and reconnect the electrical connectors.

5. Final Checks

Reconnect the battery terminals.
Ensure everything is secure and tidy under the hood.
