Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Disconnect the negative battery terminal to avoid electrical shock.

2. Inspect and Clean Battery Connections

Remove the positive (+) and negative (-) battery terminals using a socket wrench.
Clean the battery terminals and cable connectors with a wire brush to remove corrosion.
Reconnect the battery terminals, ensuring they are tight and secure.

3. Test or Replace the Battery

If the battery voltage is below 12.4 volts, consider charging the battery using a battery charger.
If charging does not resolve the issue, replace the battery with a new one (ensure it is the correct size and type).
Properly connect the new battery, starting with the positive terminal followed by the negative terminal.

4. Inspect and Replace the Starter Motor (if necessary)

If the starter motor is suspected, locate it (usually near the bottom of the engine near the transmission).
Disconnect the wiring harness and the battery connections to the starter.
Remove the starter motor mounting bolts with a socket wrench.
Replace the starter motor with a new or remanufactured unit, following the manufacturer’s torque specifications for the bolts.
Reconnect the wiring harness and battery connections.
