WARNING: This page is about a different variant/trim than selected.
NOTE:
Right Hand Drive (RHD) vehicle is shown, Left Hand Drive (LHD) vehicle is similar.
The BCM /GWM is attached to a bracket and bolted to the passenger side of the cross-car beam, behind the glovebox.
The BCM /GWM is located adjacent to the PJB, and it is the main controller of the vehicle body systems.
The BCM /GWM contains software to control the following functions:
- Determine the condition of the startup battery.
- DC/DC
output:
- Control the DC/DC output to reach a desired system voltage.
- Control the DC/DC output to reach a target startup battery State of Charge.
- Load management:
- Load management controls the 12V power system to make sure that the system is not overloaded. In certain events, for example, during engine stop/start, some systems can be switched OFF.
- Control stop/start system functionality:
- The BCM /GWM can only inhibit stop/start functionality depending on the power system condition.
- The BCM /GWM also provides supporting functionality through load management.
The BCM /GWM communicates with other system control modules on the following:
- FlexRay
- HS CAN powertrain systems bus
- HS CAN power mode zero systems bus
- HS CAN Underbody (UN) systems bus
- HS CAN Human Machine Interface (HMI) systems bus
- HS CAN body systems bus.
The BCM /GWM communicates with the BMS control module through a LIN.
