PDC: electronic parking aid
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
From the F01 onwards, the hardware of the electronic parking aid is integrated in the hardware of the JBE control module. The function of the parking aid has a separate processor. This is why the parking aid has no address of its own on the CAN bus. The parking aid can be treated as a separate control module with regard to diagnosis. The PDC control module has its own fault memory and is listed separately in the control-module functions.
As the hardware of the PDC control module is integrated in the hardware of the JBE control module, the JBE control module supplies power to the PDC control module.
