Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, battery tester, socket set, torque wrench.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent any electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion from terminals using a wire brush.
- Tighten any loose terminal connections.
If the battery is faulty:
- Remove the old battery (usually involves disconnecting negative first, then positive).
- Install a new battery, connecting positive first, followed by negative.
- Torque the battery terminals to the manufacturer's specifications (typically around 10-15 ft-lbs).

3. Starter Motor Inspection and Replacement

Check Connections:
- Inspect the wiring on the starter motor for any signs of wear or damage.
- Tighten connections as necessary.
If starter is faulty:
- Remove the starter motor from the vehicle (may require removing heat shields or other components depending on access).
- Install the new starter motor, ensuring all connections are secure.
- Torque mounting bolts to manufacturer specifications (typically around 25-30 ft-lbs).

4. Final Checks

Reconnect the negative battery terminal.
Clear any trouble codes from the OBD-II scanner.
Attempt to start the vehicle. If it starts, monitor for any unusual sounds or warning lights.
