Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, OBD-II scanner, and safety gloves.
Ensure the vehicle is in park and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion from battery terminals using a wire brush.
- Tighten the connections securely.
Test Battery Voltage:
- Reconnect the negative terminal.
- Use a multimeter to check voltage; replace the battery if voltage is below 12.4 volts.

3. Starter Motor and Solenoid Check

Remove Starter Motor:
- Disconnect wiring harness from the starter.
- Unbolt the starter using the socket set (typically two or three bolts).
Test Starter Functionality:
- Use a multimeter to check for voltage at the starter when the key is turned.
- If there is voltage and the starter does not engage, replace the starter motor.

4. Ignition Switch and Wiring Inspection

Inspect Ignition Switch:
- Remove the steering column cover to access the ignition switch.
- Check for continuity using a multimeter when the key is turned to the start position.
Check Wiring:
- Inspect wiring for any frays or damages leading to the starter and ignition switch.
