USB Port Inspection

Switch the ignition ON (engine off).
Measure the voltage between the USB port power supply and GND.

If the voltage is from 4.75 V to 5.25 V:
- The USB power outlet is normal.
If the voltage is less than 4.75 V or higher than 5.25 V:
- Replace the USB power outlet. (See USB PORT REMOVAL/INSTALLATION (US) .)
