Line resistance too high during USB test
The curve progression on the green line (1) drops off significantly in the illustration that is displayed. (Voltage less than 3.9 V at 500 mA)
NOTE:
With several USB devices, a voltage of around 4 V is not sufficient to guarantee the function.
However, the vehicle is trouble-free! In this case, use a different USB device.
Troubleshooting:
- Check USB cable connection between IMIB and vehicle (use spare cable from another IMIB if necessary).
- Check the USB connection.
- Check wires and plug connections in vehicle.
