Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, wrench set, battery terminal cleaner, safety glasses, gloves.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Battery Inspection

Remove the positive terminal first, followed by the negative terminal.
Clean the battery terminals using a battery terminal cleaner to remove corrosion.
Reconnect the terminals securely, ensuring they are tight.

3. Battery Replacement (if necessary)

If the battery is found to be defective, remove it from the vehicle:
1. Use a wrench to loosen the battery hold-down clamp.
2. Carefully lift the battery out of the tray (consider weight).
Replace with a new battery that meets OEM specifications.
Secure the new battery in place and reconnect the terminals.

4. Starter Motor Check

Locate the starter motor (usually near the transmission).
Inspect the wiring harness connected to the starter for any damage.
Use a multimeter to test for voltage at the starter when the ignition key is turned to the start position. If there is no voltage, further investigate the ignition switch or wiring.

5. Testing the Starter Motor

If voltage is present but the starter does not engage:
1. Remove the starter motor from the vehicle by disconnecting the wiring and removing the mounting bolts.
2. Bench test the starter motor using a battery to see if it spins.
3. If the starter fails to operate, replace the starter motor.
