Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety gloves.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Battery Inspection

Disconnect Battery: Remove the negative terminal first, followed by the positive terminal.
Clean Terminals: Use a wire brush to clean any corrosion from the battery terminals and cable ends.
Reconnect Battery: Reattach the positive terminal followed by the negative terminal.

3. Starter Relay and Fuse Check

Locate the Relay: Find the starter relay in the fuse box (refer to the owner's manual).
Swap Relay: Remove the starter relay and replace it with a similar relay from the vehicle.
Check Fuses: Inspect the fuse for the starter circuit; replace if blown.

4. Starter Motor Inspection

Locate Starter Motor: Access the starter motor under the vehicle.
Inspect Connections: Check for loose wires and tight connections at the starter.
Test Starter: If accessible, use a jumper wire to directly apply power to the starter. If it does not engage, replace the starter motor.

5. Final Assembly

If components were removed or replaced, double-check all connections and ensure the battery terminals are secure.
Reinstall any covers or components that were removed for access.
