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 ABS, traction control, ESC, RSCand the automatic release feature of the electronic parking brake system.
Adaptive cruise control braking deceleration	CCM	This message is used to request vehicle deceleration by the ABS module to maintain the distance gap set by the driver for the adaptive cruise control system.
Adaptive cruise control brake torque request	CCM	This message informs the ABS module of the amount of braking required to maintain the distance gap set by the driver for the adaptive cruise control system.
Adaptive cruise control precharge request	CCM	This message is used to request precharging of the hydraulic brake system in preparation of a adaptive cruise control braking event.
Ambient air temperature	PCM	This message informs the ABS module of the current ambient air temperature. The ABS module uses this information for system diagnostics and DTC setting conditions.
AWD locking status	PCM	The ABS module uses AWD information for correct operation of the ABS and stability control systems.
Brake on-off switch	PCM	This message informs the ABS module the driver has pressed the brake pedal. This message is also used by the ABS module to check the brake pressure sensor located inside the HCU.
Brake pedal applied	PCM	This message informs the ABS module the driver has pressed the brake pedal. This message is also used by the ABS module to check the brake pressure sensor located inside the HCU.
Cruise control status	PCM	This message informs the ABS module of the current cruise control system status; off, denied, standby denied, standby active que assist, active or undefined.
Clutch pedal applied	PCM	This message informs the ABS module the driver has pressed the clutch pedal.
Collision mitigation by braking deceleration	CCM	This message is used to request vehicle deceleration by the ABS module for the collision avoidance system.
Collision mitigation by braking precharge request	CCM	This message is used to request precharging of the hydraulic brake system in preparation of a severe braking event.
Door ajar status	BCM	This message informs the ABS module of the current door ajar status. There is a separate message for each door and liftgate. The ABS module resets the parameters used for the ESC and RSC functions when a door is opened. The message is also used for the electronic parking brake automatic release feature.
Driven wheel torque	PCM	This message informs the ABS module of the current torque output at the driven wheels. This information is use for traction control and stability control purposes.
Engine disable status	PCM	This message informs the ABS module the engine is currently disabled or enabled due to the stop-start system.
Engine RPM	PCM	This message informs the ABS module of the current engine RPM. This information is used for traction control and stability control purposes.
Engine status	PCM	This message informs the ABS module of the current status of the engine system; off, on, hot or cold.
Gear lever position	PCM	This message informs the ABS module of the current transmission gear lever position, this is used for the hill start assist system, the ESC and the RSC systems. The hill start assist system operates in forward and reverse gears. The ESC and RSC systems do not operate when the transmission is in REVERSE. The message is also used for the electronic parking brake automatic release feature.
Hill start assist request	IPC	This message is sent from the IPC and relayed to the ABS module from the BCM. This message informs the ABS module of the current, driver selected mode for the hill start assist system; off, auto or manual.
Ignition status	BCM	This message informs the ABS module of the current ignition status; off, accessory, run, start, unknown or invalid.
Odometer master value	IPC	This message informs the ABS module of the current odometer value in kilometers.
Powertrain status	PCM	This message informs the ABS module of the current engine status; initialization, awake, ready, prestarting, starting in progress, running, running_standby, running_start in progress, running_remote started, after run and undefined.
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 ACC. Over time, the ABS module learns the offset of the sensors inside the RCM. When a new serial number is found and the IVD Initialization procedure is carried out using a scan tool, the ABS module resets the offset number learned for ESC and RSC.
Steering angle sensor data	SASM	Several steering angle messages are sent to the ABS module from the SCCM. These messages include steering angle sensor status, steering wheel angle and steering wheel rotation count. The ABS module uses the steering angle sensor data for ESC and RSC system operation.
Torsion bar data	PSCM	The steering gear uses an internal torsion bar between the steering wheel and the steering gear. This torsion bar is used to measure the torque being applied to the steering system, the direction of steering wheel travel and how fast the steering wheel is being turned. This information is sent to the ABS module from the PSCM. The ABS module uses the torsion bar data for ESC and RSC system operation.
Traction control configuration	IPC	This message is sent from the IPC and relayed to the ABS module from the BCM. This message informs the ABS module of the current MyKey® traction control configuration; always on or selectable.
Traction control mode request	IPC	This message is sent from the IPC and relayed to the ABS module from the BCM. This message informs the ABS module of the current driver requested traction control mode: on or off.
Transmission in reverse	PCM	This message informs the ABS module when the transmission is shifting gears. This information is used for stability control purposes.
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.
Vehicle lateral acceleration data	RCM	This message provides the ABS module with the current vehicle lateral acceleration information and whether or not the information is valid.
Vehicle longitudinal acceleration data	RCM	This message provides the ABS module with the current vehicle longitudinal acceleration information and whether or not the information is valid.
Vehicle roll rate data	RCM	This message provides the ABS module with the current vehicle roll rate information and whether or not the information is valid.
Vehicle yaw data	RCM	This message provides the ABS module with the current vehicle yaw information and whether or not the information is valid.
