The cost to diagnose the B1252 Ford code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
The media hub requires an external power and ground circuit to operate. Loss of power or ground disables all media hub functionality. One USB cable connects the media hub to the Accessory Protocol Interface Module (APIM). The OBDII code sets when the APIM detects an over-current condition in the USB circuit. This can be caused by a fault in the USB cable and port, or by the customer USB device.
