External Controls (G2348431): Operation: Notes
Rotation of the Transmission Control Switch (TCS) to any of the 5 positions is sensed by the Transmission Control Module (TCM). The TCM receives the signals from the TCS through the High Speed (HS) Controller Area Network (CAN) powertrain systems bus. The TCM then reacts according to the selected position.
With the brake pedal applied, rotate the TCS to select DRIVE, NEUTRAL, REVERSE or PARK position.
When in DRIVE mode, depress the TCS and rotate, SPORT mode can be selected.
Once the TCS position is confirmed, the TCM outputs appropriate information on the FlexRay to the Transfer Case Control Module (TCCM). Then the TCCM transmits the information to the Body Control Module/Gateway Module (BCM/GWM) through the FlexRay. The Instrument Cluster (IC) receives the information through the HS CAN comfort systems bus from the BCM/GWM. The gear selection information is displayed in the message center.
