Solution

1. Preparation

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

2. Battery Inspection

Disconnect Battery: Use a socket wrench to disconnect the negative terminal first, followed by the positive terminal.
Clean Terminals: Use a wire brush to clean any corrosion from the battery terminals and connectors.
Reconnect Battery: Reconnect the positive terminal first, followed by the negative terminal.

3. Starter Relay and Fuse Inspection

Locate the Fuse Box: Open the fuse box under the hood.
Check Relay: Remove the starter relay and visually inspect it; if it shows signs of damage, replace it.
Check Fuses: Inspect the relevant fuses for the starting system; replace any blown fuses.

4. Starter Motor Replacement (if necessary)

Remove Battery: Disconnect the battery again if it was reconnected.
Access Starter: Remove any components obstructing access to the starter motor (like the air intake or heat shield).
Disconnect Starter: Unbolt the starter motor from its mount and disconnect the wiring harness.
Install New Starter: Position the new starter in place, connect the wiring harness, and secure it with bolts to the mounting bracket.
Reassemble Components: Reinstall any components that were removed to access the starter.
