Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper cables.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.
Disconnect the battery by removing the negative terminal first.

2. Battery Inspection

Inspect Battery Terminals:
1. Clean any corrosion from the battery terminals using a wire brush.
2. Tighten the connections to ensure they are secure.
Test Battery Voltage:
1. Reconnect the battery and use a multimeter to check voltage.
2. If below 12.6 volts, replace the battery.

3. Starter Motor Testing

Access the Starter Motor:
1. Remove any components obstructing access to the starter motor (e.g., air intake duct).
Perform Direct Voltage Test:
1. Connect a jumper wire directly from the battery positive terminal to the starter motor terminal.
2. If the starter engages and the engine cranks, the starter is functional, and the issue may be electrical.

4. Ignition Switch and Fuses

Inspect the Ignition Switch:
1. Remove the ignition switch cover.
2. Test the switch for continuity using a multimeter when the key is turned to the start position.
Check Fuses:
1. Locate the fuse box and inspect fuses related to the ignition and starting system.
2. Replace any blown fuses with the appropriate amperage.
