Audio System - Project 8 (G2231240): Operation

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.

The Infotainment Master Controller (IMC) is subject to the power management of the quiescent current relay. Power management is controlled by the Body Control Module/Gateway Module (BCM/GWM).

For additional information, Refer to: QUIESCENT DRAIN

The BCM/GWM controls the quiescent current relay in the EJB. The BCM/GWM receives startup battery status signals transmitted by the Battery Monitoring System (BMS) control module. The BCM/GWM can disable the power supply to other non-essential control modules to avoid excessive discharge of the startup battery. The systems supplied via the quiescent current relay are the infotainment systems and the climate control systems.

The IMC is connected to the Touchscreen (TS) via an Automotive Pixel Link 2 (APIX2) connection. APIX2 is a high speed data transmission over 2 twisted pair cables. TS selections by the driver are passed to the IMC on the APIX2 connection for processing.

The front portable media interface panel is connected to the IMC with Universal Serial Bus (USB) data links and an APIX2 connection. The USB sockets provide a 5V charging output for the connected device and also provide external connection of a device to the IMC. The APIX2 connection provides video input into the IMC from an external device. Power is supplied to the portable media interface panel from a fuse in the EJB, via the quiescent current relay and a fuse in the Rear Junction Box (RJB).

The Audio Amplifier Module (AAM) receives a power supply via a fuse in the Battery Junction Box (BJB), the Voltage Quality Module (VQM) and a fuse in the RJB.

Video data is passed from the IMC to the Instrument Cluster (IC) on APIX2 connection. The data connection provides video output from the IMC for user interface information to be displayed in the IC.
