INCONTROL Touch Systems

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

A permanent battery supply is provided to the Audio Head Unit (AHU) from the Battery Junction Box (BJB), via the Quiescent Current Control Module (QCCM).

The QCCM receives battery status signals transmitted by the Battery Monitoring System (BMS) control module. The QCCM can disable the power supply to other non-essential control modules to avoid excessive discharge of the battery. The systems supplied via the QCCM are the infotainment systems and the climate control systems. For additional information, Refer to: BATTERY AND CABLES

The AHU is connected to the Touch Screen (TS) via an Automotive Pixel Link2 (APIX2) connection. APIX2 is a high speed data transmission over a single twisted pair cable. The TS selections by the driver are passed to the AHU on the APIX2 connection for processing.

The portable audio interface panel is connected to the AHU with Universal Serial Bus (USB) data links. The USB sockets provide a 5 V charging output for the connected device and also provide external connection of a device to the AHU.
