USB test with the (IMIB) Integrated Measurement Interface Box

The Integrated Measurement Interface Box (IMIB) makes it possible to test the USB ports in the vehicle. Two tests are available for this purpose in the IMIB. The CURRENT CHECK is an electrical test of the USB interface, whereby only the vehicle-side power supply and the current level of the USB connection are tested. With the MEDIA TEST, various media files are made available via USB and are played back in the vehicle.

NOTE: It is not necessary to connect the IMIB to the network or an ISID in order to carry out the USB test. The results of the USB tests are not included in the diagnosis report. The USB tests must be used as independent tools for diagnosing vehicle belonging to the BMW group. 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 connection is only fully functional if both tests can be successfully completed. Only the electrical test (current check) for voltage and current can be carried out at the USB connection in the glove compartment (not the media test). If one of the two tests is not performed successfully, a vehicle diagnosis must be carried out with the ISTA! 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!)

NOTE: Only perform USB test 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.

Proceed as follows to perform the USB test:

Open up the menu on the IMIB by pressing the MENU button. Select USB TESTS using the navigation buttons, and confirm with the OK button.

The initialization of the USB test is performed. For system-related reasons, it takes up to approx. 6 seconds until initialization is complete. After the IMIB has been rebooted, it may be necessary to wait for approx. 40 seconds.
