Solution

1. Preparation

Ensure the vehicle is in a safe location and turned off.
Gather tools and equipment: OBD-II scanner, multimeter, socket set.

2. Check and Charge the 12V Battery

Tools Required: Multimeter, battery charger.
Measure the voltage of the 12V battery using a multimeter. It should be above 12.4 volts.
If the voltage is low, connect a battery charger to the 12V battery and charge it to full capacity.
Once charged, attempt to start the vehicle again.

3. Inspect the Main Battery Pack

Tools Required: Multimeter.
Measure the voltage of the main battery pack at the terminals.
If the voltage is significantly below expected (less than 300 volts), the battery may require service or replacement.

4. Check Connections to the Starter

Tools Required: Socket set.
Visually inspect and tighten all connections to the starter motor.
Clean any corrosion from terminals if present.

5. Reset the Vehicle

Tools Required: None.
Perform a soft reset of the vehicle by holding down the brake pedal and pressing the start button for 10 seconds until the screen resets.
