Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area with no active alerts on the dashboard.
Disconnect the negative battery terminal to prevent electrical issues while working.

2. Update Software

Reconnect the vehicle to Wi-Fi.
Go to the software update section in the settings menu.
Follow prompts to download and install any available updates.
Reconnect the battery terminal after updates are completed.

3. Inspect Accelerator Pedal Sensor

Locate the accelerator pedal assembly under the dashboard.
Disconnect the wiring harness from the accelerator pedal sensor.
Use a multimeter to test for proper voltage and resistance readings according to the manufacturer's specifications.
Replace the sensor if readings are outside the specified range.

4. Examine Throttle Body

Remove any covers or components obstructing access to the throttle body.
Inspect for carbon buildup or debris; clean using throttle body cleaner and a soft brush.
Reconnect all components and ensure a proper seal.

5. Brake System Check

Inspect the brake pedal switch for proper operation.
Ensure that the brake hold feature is not activated when it shouldn’t be.
Test the brake system operation to ensure that the pedal fully returns to its original position.
