Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Disconnect the negative terminal of the battery to avoid accidental short circuits.
Clean the battery terminals using a battery terminal cleaner to remove any corrosion.
Reconnect the terminals tightly and check for any physical damage to the battery.

3. Starter Relay and Fuse Check

Locate the fuse box under the hood and find the starter relay.
Remove the relay and check for continuity using a multimeter.
If faulty, replace the relay with a new one.
Inspect the starter fuse for any signs of damage; replace if necessary.

4. Starter Motor and Wiring Inspection

If the relay and fuse are functional, locate the starter motor.
Check the wiring connections to the starter motor for any damage or loose connections.
If accessible, perform a voltage drop test on the starter motor circuit.

5. Replace Battery/Starter (if necessary)

If the battery voltage is low or the battery has failed, replace it with a new one of the same specifications (usually a Group 48 or equivalent).
If the starter motor is found to be defective, remove it using a socket set, install the new starter, and torque bolts to manufacturer specifications.
