Body Control Module/Gateway Module
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 Body Control Module/Gateway Module (BCM/GWM) is attached to a bracket, which is attached to the lower A-pillar on the passenger side of the vehicle.
The BCM/GWM contains software to control the following functions:
- Determine the condition of the startup battery.
- Control the output from the generator using load management software.
- Controls the auto stop/start system using power management to inhibit unnecessary electrical loads.
The BCM/GWM communicates with other system control modules on the Flexray and High Speed (HS) Controller Area Network (CAN) systems buses.
The BCM/GWM communicates with the following via the Local Interconnect Network (LIN) bus:
- Battery Monitoring System (BMS) control module
- Quiescent Current Control Module (QCCM)
- Voltage Quality Module (VQM)
- Generator.
The BCM/GWM monitors the components and can store fault related Diagnostic Trouble Codes (DTCs).
