Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, wrench set, and OBD-II scanner.
Ensure the vehicle is in "Park" or "Neutral" before starting repairs.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Check Battery Condition
- Reconnect the negative terminal after confirming battery health.
- If voltage is low, charge the battery fully or replace it if necessary.
Inspect Battery Terminals
- Clean any corrosion on the battery terminals using a wire brush.
- Ensure the terminals are securely tightened.
Jump-Start the Vehicle
- Connect jumper cables to the dead battery (red to positive, black to negative).
- Connect the other end to a functioning battery and attempt to start the vehicle.
Replace the Battery (if needed)
- If the battery is faulty, remove it by unbolting it from the tray.
- Install a new battery ensuring correct terminal orientation.
- Tighten the terminal connections securely.

3. Starter Motor Inspection

Inspect Starter Connections
- Disconnect the negative terminal again.
- Locate the starter motor and check the wiring for loose connections.
- Tighten any loose bolts and connectors.
Test Starter Operation
- With the battery reconnected, use a multimeter to check for voltage at the starter when the ignition is turned.
- If no voltage is present, the ignition switch may be faulty.
Replace Starter (if necessary)
- If the starter is not engaging, remove the starter motor by unbolting it from its mount.
- Install the new starter motor and reconnect the wiring.
