USB test for USB interface

The Integrated Measurement Interface Box (IMIB) makes it possible to test the USB ports in the vehicle. Two tests are available. The load test is an electrical test of the USB interface, whereby only the vehicle-side voltage supply and the current level of the USB port are tested. With the media test , various media files are made available via USB and can be played back in the vehicle. A procedure is available in the diagnosis system ISTA for the USB test, which can be carried out via the Integrated Service Information Display (ISID).

NOTE: It is necessary to connect the IMIB to an ISID via the network in order to carry out the USB test. The results of the USB tests are included in the diagnosis report. The testing of other USB components (PC, data carriers, accessories etc.) is not permitted and could cause permanent damage to the IMIB. The tested USB port is only fully functional if both tests are successfully completed. If one of the two tests is not performed successfully, a vehicle diagnosis must be carried out with the ISTA and the wiring and plug connections checked against the wiring diagram! Warranty-related invoicing can only take place after a full diagnosis has taken place.

In order to carry out the USB tests successfully, the following general conditions must be taken into consideration.

Latest software and updates installed on the IMIB.
Battery charger connected.
Ignition turned on.
Connect USB cable to IMIB (do not connect USB cable to vehicle yet!)
Make sure that no test function is activated on the Integrated Measurement Interface Box (only start screen). Dropped connections between ISID and IMIB are possible if a test function is activated on the IMIB.

NOTE: Only perform the USB tests with the USB cable provided in the scope of delivery of the IMIB. Always perform USB tests directly at the USB connection of the vehicle! Do not use extension cables, USB hubs etc.

The examples listed in the description only relate to testing on BMW vehicles. The system behaves identically for vehicles of the type MINI or Rolls-Royce.

The USB test must be carried out in accordance with the instructions contained in the testing procedure.
