Solution

1. Preparation

Tools Required: Multimeter, socket set, OBD-II scanner, remote starter switch.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Clean battery terminals and ensure they are tight.
2. If the battery voltage is low (below 12.4 volts), charge or replace the battery.
3. Reconnect the battery terminals securely.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor (typically near the transmission).
2. Use a remote starter switch to apply power directly to the starter motor.
3. If the starter engages and the engine cranks, the starter is functional.
4. If it does not crank, replace the starter motor.

4. Ignition Switch and Fuses

Sub-steps:
1. Inspect and test the ignition switch with a multimeter to verify it's functioning correctly.
2. Replace any blown fuses related to the starting system.
3. If the ignition switch is faulty, replace it.

5. Reassembly and Final Checks

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle to check for successful operation.
3. If the issue persists, further diagnostic work on the immobilizer system or wiring may be necessary.
