Solution

1. Preparation

Tools Required: Multimeter, OBD-II scanner, basic hand tools.
Ensure the vehicle is in a safe location, and all electrical systems are powered down.

2. Check and Charge the 12V Battery

Sub-steps:
- Open the front trunk to access the 12V battery.
- Use a multimeter to measure the voltage of the 12V battery.
- If the voltage is below 12.4 volts, charge the battery using a compatible battery charger.
- Ensure the charger is set to the correct voltage for a 12V battery.

3. Inspect the Key Fob

Sub-steps:
- Open the key fob and replace the battery if it is low (typically a CR2032 battery).
- Test the key fob by pressing the buttons to ensure it is functioning.
- If available, use a spare key fob to attempt starting the vehicle.

4. Check Brake Pedal Switch

Sub-steps:
- Locate the brake pedal switch, typically mounted near the top of the brake pedal.
- Inspect the wiring and connector for any visible damage.
- Use a multimeter to test the switch for continuity; replace if defective.

5. Diagnostic Scan

Sub-steps:
- Connect an OBD-II scanner to the vehicle's diagnostic port.
- Check for any stored trouble codes that may indicate a fault in the starting system.
- Address any issues indicated by the codes, which may include faulty sensors or modules.
