Solution

1. Preparation

Tools Required: Multimeter, load tester, socket set, wrench set, OBD-II scanner.
Ensure the vehicle is in a safe location, parked on a level surface, and the ignition is off.
Safety Warnings: Disconnect the negative battery terminal before working on electrical components.

2. Battery Inspection

Remove the negative battery terminal using a wrench.
Clean any corrosion from the battery terminals using a wire brush.
Reconnect the terminals securely, ensuring a tight fit.

3. Battery Replacement (if necessary)

If the battery is weak or failed the load test, remove the positive terminal followed by the negative terminal.
Remove the battery hold-down bracket and lift the battery out.
Install the new battery, securing it with the bracket.
Connect the positive terminal first, followed by the negative terminal.

4. Starter Motor and Solenoid Replacement (if necessary)

If the starter motor is found to be faulty, disconnect the negative battery terminal again.
Locate the starter motor (generally near the transmission).
Remove the electrical connections to the starter motor.
Unbolt the starter from its mounting location.
Install the new starter motor by reversing the removal steps and tightening bolts to the manufacturer’s specified torque.
