Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrench set, and cleaning solution.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery.
2. Clean the battery terminals using a battery terminal cleaner if corrosion is present.
3. Reconnect the battery terminals securely.

3. Starter Relay Replacement

Sub-steps:
1. Locate the fuse box under the dashboard or hood.
2. Identify the starter relay and remove it.
3. Replace it with a new starter relay or a similar relay from the fuse box.

4. Starter Motor Testing

Sub-steps:
1. Disconnect the starter motor electrical connector.
2. Use a multimeter to test the voltage at the starter motor terminal while someone turns the key to the start position.
3. If no voltage is present, further inspect the ignition switch and wiring.
4. If voltage is present, proceed to remove the starter motor for inspection.

5. Starter Motor Replacement (if necessary)

Sub-steps:
1. Remove the starter motor by disconnecting its electrical connections and mounting bolts.
