Infotainment Master Controller

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 primary battery supply is provided to the Infotainment Master Controller (IMC) 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

If the ambient air temperature is below -40°C (-40°F), the IMC will not start. If the ambient air temperature is above 70°C (158°F) the IMC will shut down. For additional information, refer to: AUDIO SYSTEM
