1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver, and safety glasses.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Battery Service

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

3. Starter Relay Replacement

Access Fuse Box: Open the fuse box cover located under the dashboard or hood.
Locate Starter Relay: Identify the starter relay based on the diagram inside the fuse box cover.
Remove Relay: Pull the relay out gently using pliers if necessary.
Install New Relay: Insert the new starter relay into the same slot securely.

4. Ignition Switch Testing

Remove Ignition Switch Cover: Use a screwdriver to remove screws and take off the cover.
