Solution

1. Preparation

Tools Required: Multimeter, socket set, OBD-II scanner, wire brush (for cleaning terminals), wrenches.
Ensure the vehicle is in park and the ignition is off. Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Cleaning

Remove the battery terminals (negative first, then positive).
Use a wire brush to clean any corrosion from the terminals and battery posts.
Reconnect the battery terminals tightly and ensure a secure connection.
Reconnect the negative terminal last.

3. Fuse and Relay Check

Locate the fuse box (refer to the vehicle manual for location).
Remove the starter relay and inspect for continuity using a multimeter.
Replace any blown fuses related to the starting system and the starter relay if necessary.

4. Testing the Ignition Switch

Locate the ignition switch and check its operation.
If malfunctioning, remove the ignition switch and replace it with a new one, ensuring all connectors are secure.

5. Starter Motor Inspection

If the previous steps do not resolve the issue, locate the starter motor.
Inspect the wiring harness connected to the starter for any signs of damage.
Use a multimeter to check for voltage at the starter terminal when the ignition is turned on.
If there is no voltage, the starter may need replacement.
