Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is in park and the parking brake is engaged.
Disconnect the negative battery cable to prevent electrical shocks.

2. Battery Inspection and Replacement

Tools Required: Wrench set, multimeter, battery terminal cleaner.
Clean battery terminals using terminal cleaner or a wire brush to remove corrosion.
Use a multimeter to check battery voltage; if it’s below 12.4 volts, proceed to replace the battery.
Remove the old battery by loosening the terminal connections (negative first, then positive).
Install the new battery by connecting the positive terminal first, followed by the negative.

3. Starter Motor Inspection

Tools Required: Socket set, ratchet, torque wrench.
Locate the starter motor, usually situated near the bottom of the engine near the transmission.
Disconnect the wiring harness from the starter motor.
Remove the starter motor mounting bolts and take out the starter.
Inspect the starter for any signs of damage or wear; replace if necessary.

4. Replace Starter Relay (if necessary)

Locate the fuse box and identify the starter relay.
Remove the faulty starter relay and replace it with a new one.
Ensure it is properly seated in the fuse box.
