Solution

1. Preparation

Ensure the vehicle is parked safely and the ignition is off.
Gather tools and equipment: OBD-II scanner (if necessary), multimeter for battery testing, and a soft cloth for cleaning connections.

2. Update Software

Connect to Wi-Fi and navigate to the software update section in the settings.
Download and install any available updates, following on-screen prompts.

3. Inspect and Test the 12V Battery

Use a multimeter to check the voltage of the 12V battery; it should be around 12.6 volts when fully charged.
If the voltage is low, clean the battery terminals with a soft cloth and re-tighten connections. If the battery is defective, consider replacing it.

4. Reset Infotainment System

While the vehicle is on, press and hold both scroll wheels on the steering wheel until the display goes black and then reboots.
Wait for the system to restart and check if the odometer display functions properly.

5. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel assembly.
Visually check for damage or disconnections; if damaged, replace the sensor.
If necessary, use an OBD-II scanner to check for error codes related to the ABS or traction control systems that might indicate a faulty sensor affecting the odometer.
