Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and cleaning supplies.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal for safety.

2. Battery Inspection and Replacement

Inspect the Battery
- Clean any corrosion from the battery terminals using a wire brush and baking soda solution.
- Tighten the battery terminals.
Test the Battery
- If the voltage is below 12.4 volts, charge the battery or replace it if it fails to hold a charge.
- Use a battery load tester to confirm battery health.
Replace Battery (if necessary)
- Remove the old battery by loosening the terminal bolts and lifting it out of the tray.
- Install the new battery by placing it in the tray and securing it with the hold-down mechanism.
- Reconnect the terminals, starting with the positive terminal followed by the negative terminal.

3. Starter and Electrical System Check

Inspect and Test Starter
- Remove the starter by disconnecting the battery again, then the electrical connectors, and unbolting it from the engine.
- Test the starter on a bench to see if it engages.
- If defective, replace with a new starter.
Check Wiring and Connections
- Inspect all wiring leading to the starter and battery for damage or loose connections.
- Repair or replace any damaged wires.

4. Reassembly and Final Checks

Reinstall Components
- Reinstall the starter and connect all electrical connectors and bolts.
- Reconnect the negative battery terminal.
Final Inspection
- Ensure all tools are removed from the engine bay.
- Check that all connections are secure.
