Solution

1. Preparation

Gather tools: socket set, multimeter, wrench set, and OBD-II scanner.
Ensure the vehicle is in a safe location, and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion on terminals using a wire brush.
- Tighten loose connections securely.
Replace Battery (if necessary):
- Remove the positive terminal first, followed by the negative terminal.
- Unbolt the battery hold-down clamp and lift the battery out.
- Install the new battery, securing it with the hold-down clamp.
- Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Check and Replacement

Check Starter:
- Locate the starter motor and ensure all electrical connections are secure.
- If bypassing the starter with a jump wire confirmed it was faulty, proceed to replace it.
Replace Starter:
- Disconnect the negative battery terminal again.
- Remove the wiring harness from the starter.
- Unbolt the starter from the engine block (note any mounting torque values).
- Install the new starter and reconnect wiring.
- Reconnect the negative battery terminal.

4. Final Checks

Ensure all connections are tight and secure.
Recheck fuses related to the starting system and replace if necessary.
