Solution

1. Preparation

Tools Required: Battery terminal cleaner, multimeter, OBD-II scanner, socket set, torque wrench, battery load tester.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Clean the battery terminals using a battery terminal cleaner to remove any corrosion.
2. Reconnect the battery terminal and ensure it is tight.
3. If the battery voltage is low or fails the load test, remove the battery using a socket set.
4. Replace the battery with a new one that matches the manufacturer's specifications.
5. Reconnect the battery, ensuring proper terminal connection.

3. Starter Relay and Fuse Check

Sub-steps:
1. Locate the fuse box and identify the starter fuse. Remove it and inspect for continuity.
2. If blown, replace the starter fuse with one of the same amperage.
3. Check the starter relay by removing it and testing for continuity with a multimeter. Replace if defective.

4. Starter Motor Inspection

Sub-steps:
1. If the issue persists, locate the starter motor.
2. Disconnect the wiring harness from the starter motor.
3. Use a multimeter to test for voltage at the starter motor terminal when attempting to start the vehicle.
4. If there is no voltage, trace back to the ignition switch and wiring for faults.
5. If voltage is present but the starter does not engage, replace the starter motor.
