Solution

1. Preparation

Ensure the vehicle is in a safe and secure location with adequate space.
Use a diagnostic tool to connect to the vehicle's system.
Gather required tools, including a socket set and OBD-II scanner.

2. Retrieve Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the vehicle to the "ON" position (not starting the engine).
Retrieve and note any diagnostic trouble codes displayed on the scanner.

3. Inspect Gear Shifter Assembly

Remove the center console cover using a socket set to access the gear shifter.
Inspect the shifter mechanism for any signs of debris, damage, or disconnection.
If necessary, clean or replace any damaged components.

4. Check Brake Pedal Switch

Locate the brake pedal switch beneath the dashboard.
Use a multimeter to test the switch for continuity when the brake pedal is pressed.
If the switch is faulty, replace it with a new component.

5. Update Software

Connect the vehicle to Wi-Fi and access the software update settings through the touchscreen.
Download and install any available updates.
Restart the vehicle after the update is complete to ensure all systems are functioning properly.
