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 hill start assist systems.
Ambient Air Temperature	PCM	The ABS module uses ambient air temperature for some DTC fault setting conditions.
Battery voltage	BCM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the voltage in the 12-volt battery as measured by the battery sensor.
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 as well as the brake pedal travel sensor and the brake booster travel sensor.
Car mode	BCM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current car mode. The stability systems react differently depending on the current car mode; normal, factory, transport or crash.
Door ajar status	BCM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current door ajar status. There is a separate message for each door and the liftgate. The ABS module resets the parameters used for the ESC and RSC function when a door or the liftgate is opened.
Driven wheel brake torque value	PCM and Hybrid Powertrain Control Module (HPCM)	This message provides the ABS module with the current amount of braking torque being applied to the driven wheels by the electric motor. The ABS module uses this information to help determine whether to use regenerative brake mode or friction brake mode.
Driven wheel propulsion torque value	PCM and Hybrid Powertrain Control Module (HPCM)	This message provides the ABS module with the current amount of propelling torque being applied to the driven wheels by the electric motor. The ABS module uses this information to help determine whether to use regenerative brake mode or friction brake mode.
Driven wheel brake torque request	PCM and Hybrid Powertrain Control Module (HPCM)	This message provides the ABS module with the current amount of braking torque required by the electric motor to stop the vehicle. The ABS module uses this information to help determine whether to use regenerative brake mode or friction brake mode.
Driven wheel direction	Hybrid Powertrain Control Module (HPCM)	This message provides the ABS module with the current driven wheel direction; forward, backward, unknown or failed.
Driven wheel regenerative brake monitor	Hybrid Powertrain Control Module (HPCM)	This message lets the ABS module know if the electric motor is in regenerative brake mode or not. The ABS module uses this information to determine whether or not to use friction brake mode.
Driver request traction control mode	BCM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module the driver has disabled the traction control system.
Engine status	Hybrid Powertrain Control Module (HPCM)	This message informs the ABS module of the current status of the engine system; off, on, hot or cold.
Hill start assist setting	BCM	This message is sent to the GWM and then to the ABS module. 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 is sent to the GWM and then to the ABS module. This message informs the ABS module of the current ignition status; off, accessory, run, start, unknown or invalid.
Power mode	BCM	This message is sent to the GWM and then to the ABS module. This message provides the ABS module with the current ignition status; key out, key recently out, key approved, post accessory, accessory, post ignition, ignition ON, engine running, engine running standby, engine running starting in progress and engine cranking.
Power pack status	Hybrid Powertrain Control Module (HPCM)	This message provides the ABS module with the current power pack status; awake, ready, pre-starting, starting in process, running_running, running_standby, running_starting in progress, running_remote started and after run.
Power pack torque status	Hybrid Powertrain Control Module (HPCM)	This message provides the ABS module with the current power pack torque status; power pack off - torque not available, power pack on - torque not available, power pack start in progress - torque not available or power pack on - torque available. The ABS module uses this information to help determine whether to use regenerative brake mode or friction brake mode.
RCM serial number	RCM	This message is sent to the GWM and then to the ABS module. 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.
Selector lever (PRNDL) status	PCM	This message informs the ABS module when the transmission is in REVERSE, this is used for the hill start assist system, ESC system and RSC system. The hill start assist system works in forward and reverse gears. The ESC and RSC systems do not operate when the transmission is in REVERSE.
Steering angle counter	SASM	This message is sent to the GWM and then to the ABS module. The ABS module uses steering angle sensor information for ESC and RSC system operation. This message provides the ABS with the current steering wheel angle count.
Steering angle status	SASM	This message is sent to the GWM and then to the ABS module. The ABS module uses steering angle sensor information for ESC and RSC system operation. This message provides the ABS with the current steering angle sensor status; operational with no faults detected, SASM not initialized with no faults detected and fault detected.
Steering wheel direction of travel	SASM	This message is sent to the GWM and then to the ABS module. The ABS module uses steering angle sensor information for ESC and RSC system operation. This message provides the ABS with the current steering wheel direction of travel, clockwise or counterclockwise.
Vehicle configuration data	BCM	This message is sent to the GWM and then to the ABS module. 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 provides the SASM with the current ignition status; key out, key recently out, key approved, post accessory, accessory, post ignition, ignition ON, engine running, engine running standby, engine running starting in progress and engine cranking.
