Normal Operation and Fault Conditions
The selectable drive mode switch in the center console is used to activate and deactivate the selectable drive mode feature. When the driver presses the selectable drive mode switch, the HVAC module receives a ground signal from the switch. The HVAC module sends a drive mode message to the GWM over the MS-CAN 1 and the GWM relays this message to the ABS module over the HS-CAN 2. The ABS module takes the necessary action depending on the selectable drive mode message.
