Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a wrench.
Ensure the vehicle is in a safe location, and the parking brake is engaged.

2. Battery Connection Check

Tools Required: Wrench, wire brush or battery terminal cleaner
Disconnect the negative battery terminal first, then the positive terminal.
Clean any corrosion from the terminals and battery posts.
Reconnect the positive terminal first, followed by the negative terminal.

3. Battery Testing

Tools Required: Multimeter
Set the multimeter to the DC voltage setting.
Measure the voltage across the battery terminals. A healthy battery should read between 12.4V and 12.7V.
If the voltage is below 12.4V, charge or replace the battery.

4. Starter Motor Testing

Tools Required: Socket set, jumper cables
Locate the starter motor (usually near the transmission).
Disconnect the electrical connector from the starter.
Use jumper cables to connect the starter directly to the battery to see if it engages.
If the starter does not engage, it may need to be replaced.

5. Ignition Switch Inspection

Tools Required: Screwdriver set
Remove the steering column cover to access the ignition switch.
Test the ignition switch using a multimeter to ensure it is functioning properly.
If faulty, replace the ignition switch.
