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, ESC and RSC systems.
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	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 ESC and 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, ESC, RSC and hill start assist operations.
Odometer master value	BCM	This message provides the ABS module with the current odometer value.
Parking brake actual	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.
Power mode	BCM	This message informs the ABS module of the current ignition mode; OFF, ACC, ON or START.
Power pack status	PCM	This message provides the ABS module with the current engine status; awake, ready, pre-starting, starting in process, running_running, running_standby, running_starting in progress, running_remote started and after run.
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 ESC and RSC.
Reverse gear	PCM	This message informs the ABS module when the transmission is in REVERSE, this is used for hill start assist, ESC and RSC. Hill start assist operates in forward and reverse gears. ESC and RSC do not operate when the transmission is in REVERSE.
Selector lever (PRNDL) status	PCM	This message informs the ABS module when the transmission is in REVERSE, this is used for hill start assist, ESC and RSC. Hill start assist operates in forward and reverse gears. ESC and RSC do not operate when the transmission is in REVERSE.
Steering angle counter	SASM	The ABS module uses steering angle sensor information for ESC and 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 ESC and 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).
Torsion bar torque	PSCM	The torsion bar is an internal component of the EPAS gear. The ABS module uses steering angle sensor information for ESC and RSC operation. This message provides the ABS module with the current amount of force being used to turn the steering wheel (in Newton meters) and which direction it is being turned (clockwise or counterclockwise).
Traction control deactivation mode request	BCM	This message is sent to the BCM from the IPC, the BCM then sends the message to the ABS module. The message informs the ABS module of the current MyKey ® traction control mode; always on or selectable.
Traction control mode request	BCM	This message is sent to the BCM from the IPC, the BCM then sends the message to the ABS module. The message informs the ABS module the driver has requested the traction control system be deactivated.
Trailer connect indicator	BCM	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 in reverse	PCM	This message informs the ABS module of which gear the transmission is currently using, this is used for hill start assist, ESC and RSC operation. Hill start assist operates in forward and reverse gears. ESC and 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
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.
