Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative (-) battery terminal.
2. Clean the battery terminals using a wire brush to remove any corrosion.
3. Reconnect the battery terminal securely.
4. If the battery is weak, jump-start the vehicle or replace it if necessary.
Tools Required: Wire brush, jumper cables.
Safety Warnings: Disconnect battery before working on electrical systems.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor.
2. Disconnect the electrical connector and the battery cable from the starter.
3. Use a multimeter to check for voltage at the starter terminal when the key is turned to the start position.
4. If no voltage is present, the issue may be in the ignition switch or wiring.
5. If voltage is present, connect jumper cables to the starter motor and check for operation.
Tools Required: Multimeter, jumper cables.

4. Ignition Switch Inspection

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Check for loose connections or damaged wiring.
3. Test the ignition switch with a multimeter to ensure it sends power when turned to the start position.
4. Replace the ignition switch if faulty.
