Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, battery terminal cleaner, load tester.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery by removing the negative terminal first.

2. Battery Maintenance

Sub-steps:
1. Clean any corrosion on the battery terminals using a battery terminal cleaner and a wire brush.
2. Tighten the battery connections to ensure they are secure.
3. If the battery is weak, proceed to replace it.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor (usually found near the transmission bell housing).
2. Inspect the wiring harness connected to the starter for any damage or disconnections.
3. If necessary, remove the starter motor from its mounting using the socket set.
4. Test the starter motor by connecting it directly to the battery; if it does not engage, replace the starter.

4. Reassemble and Reconnect

Sub-steps:
1. Reinstall the starter motor if it has been removed.
2. Reconnect the battery terminals, starting with the positive terminal followed by the negative terminal.
3. Ensure all tools are removed from the engine bay before starting the vehicle.
