Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrenches, and cleaning supplies.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Check Battery Condition
- Reconnect the battery and use a multimeter to measure voltage.
- If below 12.4 volts, charge the battery or replace it if it fails to hold a charge.
Clean Battery Terminals
- Remove the battery terminals (negative first).
- Clean the terminals and battery post with a wire brush and baking soda solution.
- Reconnect terminals (positive first).

3. Starter Inspection

Access Starter
- Raise the vehicle safely on jack stands.
- Locate the starter motor, typically mounted near the transmission.
Test Starter Operation
- Disconnect the starter electrical connections.
- Use jumper cables to apply power directly to the starter; it should engage and crank the engine.
- If it does not crank, replace the starter motor.
Inspect Starter Relay and Wiring
- If the starter works, check the starter relay and associated wiring for damage.
- Replace any damaged components.

4. Check Ignition Switch

Inspect Ignition Switch
- Remove the steering column cover to access the ignition switch.
- Test the ignition switch for continuity using a multimeter.
- Replace if defective.
