Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and battery terminal cleaner.
Ensure the vehicle is in a safe position with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Connections
- Clean any corrosion from battery terminals using a terminal cleaner.
- Tighten loose connections securely.
Test or Replace Battery
- If battery voltage is below 12.4 volts, perform a load test.
- If the battery fails the load test, replace it with a new one (ensure it meets OEM specifications).

3. Starter Relay and Fuse Check

Inspect Starter Relay
- Locate the starter relay in the fuse box (refer to the owner's manual).
- Swap the starter relay with a similar one to test functionality.
Examine Fuse
- Check the fuse for the starter circuit.
- Replace any blown fuses with the correct amperage.

4. Starter Motor Inspection

Access Starter Motor
- Remove any components blocking access to the starter motor (if applicable).
- Disconnect the wiring harness from the starter motor.
Test Starter Motor
- Use a multimeter to check for voltage at the starter motor terminal when the ignition is turned on.
- If no voltage is present, check wiring for continuity.
- If voltage is present but the starter does not engage, replace the starter motor.
