Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, fuse puller.
Disconnect the battery negative terminal to ensure safety while working on electrical systems.

2. Check Battery Connection

Reconnect the battery positive terminal first, followed by the negative terminal.
Ensure that the connections are clean and tight; use a battery terminal cleaner if necessary.

3. Inspect Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use a fuse puller to remove and visually inspect each fuse related to the starting system.
Replace any blown fuses with new ones of the same amperage.

4. Test Ignition Switch

If the vehicle still does not start, check the ignition switch.
Remove the ignition switch cover and use a multimeter to test for continuity when the key is turned to the "Start" position.
Replace the ignition switch if continuity is not present.

5. Reprogram Key Fob (if applicable)

If the key fob is not recognized, reprogram the key fob following the manufacturer’s instructions.
This often involves turning the ignition on and off in a specific sequence.
