Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, battery load tester, socket set.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Inspect Terminals:
- Remove the battery terminals using a socket wrench.
- Clean any corrosion from the terminals and battery posts using a wire brush.
- Reconnect the terminals securely.
Test the Battery:
- Connect the multimeter to the battery terminals and check the voltage. Charge or replace if below 12.4 volts.
- If using a battery load tester, apply a load and check if the battery holds above 9.6 volts.

3. Starter Inspection

Check Starter Connections:
- Locate the starter motor, typically near the transmission.
- Inspect the wiring connected to the starter for firmness and corrosion.
- Tighten any loose connections.

4. Starter Relay and Fuse Check

Inspect Starter Relay:
- Locate the starter relay in the fuse box.
- Test the relay with a multimeter for continuity or swap it with a similar relay in the fuse box to check functionality.
Check Fuses:
- Inspect fuses related to the ignition and starting system; replace any blown fuses.

5. Replace Components (if necessary)

If the Battery is Faulty:
- Remove the old battery and replace it with a new one, ensuring proper electrolyte levels if it’s a lead-acid battery.
If the Starter is Faulty:
- Remove the starter motor using a socket set.
- Install a new starter motor in reverse order, ensuring all connections are tight.
