Solution

1. Preparation

Gather tools: socket set, multimeter, torque wrench, and screwdriver.
Ensure the vehicle is in a safe position, with the parking brake engaged.

2. Battery Inspection

Disconnect the negative battery terminal using a socket wrench.
Clean the battery terminals and cable ends with a wire brush.
Reconnect the battery terminal and ensure it is tight.

3. Starter Relay Replacement

Locate the starter relay in the fuse box (refer to the owner's manual).
Remove the relay by pulling it straight out.
Replace it with a new relay, ensuring it is seated properly.

4. Starter Motor Testing

Remove the starter motor from the vehicle by:
- Disconnecting electrical connectors.
- Unscrewing the mounting bolts (typically 2-3 bolts).
Test the starter motor by connecting it directly to a battery. If it does not engage, replace the starter motor.

5. Reassemble and Secure Components

Reinstall the starter motor, ensuring bolts are torqued to manufacturer's specifications (usually around 15-25 ft-lbs).
Reconnect any electrical connectors removed during the process.
Reconnect the negative battery terminal.
