Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, jumper wire, and a flashlight.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery using a wrench to ensure safety.
Sub-step 2: Clean any corrosion from the battery terminals using a wire brush.
Sub-step 3: Reconnect the battery terminals securely.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor, typically found at the lower part of the engine near the transmission.
Sub-step 2: Use a jumper wire to connect the positive terminal of the battery directly to the starter motor's terminal to check for functionality.
Sub-step 3: If the starter motor engages, it may need to be replaced.

4. Fuse and Relay Replacement

Sub-step 1: Open the fuse box and locate the starter motor fuse; replace it if blown.
Sub-step 2: Identify the starter relay and replace it if testing indicates it is faulty.

5. Ignition Switch Replacement (if necessary)

Sub-step 1: Remove the steering column cover by unscrewing the necessary screws.
Sub-step 2: Disconnect the wiring harness from the ignition switch.
Sub-step 3: Remove the ignition switch from its mounting bracket and replace it with a new unit.
Sub-step 4: Reassemble the steering column cover.
