Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper cables, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the ignition is off.
Disconnect the battery negative terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Check Battery Voltage
- Use a multimeter to measure the battery voltage. Replace if below 12.4 volts.
Clean Battery Terminals
- Remove the battery terminals and clean any corrosion with a wire brush.
Reconnect Battery
- Ensure terminals are securely connected and reattach the negative terminal last.

3. Starter Relay Verification

Locate the Starter Relay
- Find the starter relay in the fuse box under the hood.
Swap with a Similar Relay
- If applicable, swap the starter relay with another relay of the same type to test functionality.
Test Relay
- If the vehicle starts, replace the faulty relay.

4. Starter Motor Testing

Access Starter Motor
- Remove any components obstructing access to the starter motor.
Directly Test Starter
- Use jumper cables to apply power directly to the starter motor terminals. If it engages, the starter is functioning; if not, it needs replacement.

5. Final Assembly

Reassemble any components removed during repair.
Reconnect the battery terminals securely.
