Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Battery Inspection

Remove the battery terminals, starting with the negative terminal.
Clean the terminals with a battery terminal cleaner to remove corrosion.
Reconnect the terminals and ensure they are tight.

3. Starter Replacement (if necessary)

Locate the starter motor under the vehicle.
Disconnect the wiring harness from the starter.
Remove the bolts securing the starter in place using a socket set.
Carefully lower the starter from its mounting location.
Install the new starter by reversing the removal steps, ensuring all connections are secure.
Torque the starter bolts to the manufacturer-recommended specifications.

4. Battery Replacement (if needed)

If the battery voltage is low, consider replacing it.
Remove the battery hold-down clamp using a socket set.
Lift the battery out of the tray carefully.
Place the new battery in the tray, ensuring the positive and negative terminals are correctly positioned.
Reinstall the hold-down clamp and tighten it securely.

5. Final Checks

Reconnect the negative battery terminal.
Start the vehicle to verify that the issue is resolved.
