Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and battery terminal cleaner.
Ensure the vehicle is in park and the ignition is off.
Disconnect the battery to prevent any electrical shorts during the repair.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion from the terminals using a battery terminal cleaner.
- Tighten any loose connections.
Test Battery Voltage:
- Connect the multimeter to the battery terminals.
- If the voltage is below 12.4 volts, charge or replace the battery.
Replace Battery (if necessary):
- Remove the negative terminal first, then the positive terminal.
- Remove any hold-down brackets and lift the battery out.
- Install the new battery by placing it in the tray, securing it with brackets, and connecting the positive terminal first followed by the negative terminal.

3. Starter System Check

Inspect Starter Connections:
- Check the connections at the starter for tightness and corrosion.
Test the Starter:
- Use a jumper wire to connect the battery positive terminal to the starter solenoid terminal to see if the starter engages.
- If the starter does not engage, it may need replacement.

4. Ground Connection Inspection

Check Ground Wires:
- Inspect the ground wires connected to the engine block and chassis for corrosion or looseness.
- Clean and tighten any loose connections.

5. Final Assembly

Reconnect the battery terminals.
Ensure all tools are removed from the engine bay.
Close the hood securely.
