Module Network Input Messages - ABS Module 

Broadcast Message Originating Module Message Purpose
Accelerator pedal position PCM The ABS module uses accelerator pedal position information for correct operation of the traction control, Electronic Stability Control (ESC) and hill start assist systems.
Brake pedal applied PCM Used to inform the ABS module the driver has pressed the brake pedal. This message is used by the ABS module to check the brake pressure sensor located inside the HCU and for hill start assist operation.
Brake on/off switch PCM Used to inform the ABS module the driver has pressed the brake pedal. This message is used by the ABS module to check the brake pressure sensor located inside the HCU and for hill start assist operation.
Car mode BCM The stability control system reacts differently depending on the current car mode; normal, factory, transport or crash. This message informs the ABS module of the current car mode.
Cruise control status PCM The CCM is an internal component of the PCM. This message informs the ABS module of the current status of the cruise control system; off, denied, standby or active.
Door ajar status BCM The ABS module resets the parameters used for Electronic Stability Control (ESC) and Roll Stability Control (RSC) when a door is opened.
Engine RPM PCM Used to inform the ABS module of the current engine Revolutions Per Minute (RPM). The ABS module uses this information for traction control, Electronic Stability Control (ESC), Roll Stability Control (RSC) and hill start assist operations.
Hood ajar status BCM The ABS module resets the parameters used for Electronic Stability Control (ESC) and Roll Stability Control (RSC) when the hood is opened.
Parking brake active BCM This message provides the ABS module with the current parking brake status; applied or not applied. This information is used for hill start assist operation.
RCM serial number RCM The ABS module stores the RCM serial number and verifies the serial number when the vehicle is started or the ignition is set to run or accessory. Over time, the ABS module learns the offset of the stability sensors inside the RCM. When a new RCM serial number is found and the Interactive Vehicle Dynamics (IVD) Initialization procedure is carried out using a diagnostic scan tool, the ABS module resets the offset number learned for Electronic Stability Control (ESC) and Roll Stability Control (RSC).
Stability-traction control mode request IPC This message is sent from the IPC to the BCM over the MS-CAN and then to the ABS module. This message informs the ABS module the driver has disabled the traction control system.
Steering angle counter SASM The ABS module uses steering angle sensor information for Electronic Stability Control (ESC) and Roll Stability Control (RSC) operation. This message provides the ABS module with the current steering wheel angle count.
Steering angle status SASM The ABS module uses steering angle sensor information for Electronic Stability Control (ESC) and Roll Stability Control (RSC) operation. This message indicates the steering wheel rotation angle (in degrees of rotation from center) and steering wheel rotation speed (in degrees per second).
Trailer brake control connection TBM This message informs the ABS module that a trailer is connected to the vehicle. The ABS module uses this information for trailer sway control operation.
Trailer connect indicator TRM This message is sent from the TRM to the BCM over the MS-CAN and then to the ABS module. This message informs the ABS module that a trailer is connected to the vehicle. The ABS module uses this information for trailer sway control operation.
Transmission gear position PCM (3.5L and 3.7L engines only) The TCM is an internal component of the PCM. This message informs the ABS module of which gear the transmission is currently using, this is used for hill start assist, Electronic Stability Control (ESC) and Roll Stability Control (RSC) operation. Hill start assist operates in forward and reverse gears. Electronic Stability Control (ESC) and Roll Stability Control (RSC) do not operate when the transmission is in REVERSE.
Transmission gear position TCM (3.2L engines only) This message informs the ABS module of which gear the transmission is currently using, this is used for hill start assist, Electronic Stability Control (ESC) and Roll Stability Control (RSC) operation. Hill start assist operates in forward and reverse gears. Electronic Stability Control (ESC) and Roll Stability Control (RSC) do not operate when the transmission is in REVERSE.
Transmission gear lever position PCM (3.5L and 3.7L engines only) The TCM is an internal component of the PCM. This message informs the ABS module of which gear the transmission is currently using, this is used for hill start assist, Electronic Stability Control (ESC) and Roll Stability Control (RSC) operation. Hill start assist operates in forward and reverse gears. Electronic Stability Control (ESC) and Roll Stability Control (RSC) do not operate when the transmission is in REVERSE.
Transmission gear lever position TCM (3.2L engines only) This message informs the ABS module of which gear the transmission is currently using, this is used for hill start assist, Electronic Stability Control (ESC) and Roll Stability Control (RSC) operation. Hill start assist operates in forward and reverse gears. Electronic Stability Control (ESC) and Roll Stability Control (RSC) do not operate when the transmission is in REVERSE.
Vehicle configuration data BCM This message provides the ABS module with the current optional and configured items such as tire size, axle ratio, manual or automatic transaxle, keyless entry and VIN.

Module Network Input Messages - SASM 

Broadcast Message Originating Module Message Purpose
Network shut down BCM This message informs the SASM the communications network is shutting down.
Network wake up BCM This message informs the SASM the communications network is activating or waking up.
Power mode BCM This message informs the SASM of the current ignition mode; OFF, ACC, ON or START.
Vehicle configuration data BCM This message provides the SASM with the current optional and configured items such as tire size, axle ratio, manual or automatic transaxle, keyless entry and VIN.
