Electronic Brake Control Module Scan Tool Data Parameters

Parameter	System State	Expected Value	Description
Operating Conditions: Ignition ON
ABS Active	-	No	The scan tool displays Yes or No. Yes is displayed if the ABS system is engaged.
ABS Failed	-	No	The scan tool displays Yes or No. Yes is displayed if there is an ABS fault.
Battery Voltage Signal	-	Varies	This displays volts. This is the voltage status of the electronic brake control module (EBCM).
Brake Fluid Level Status	-	OK	The scan tool displays OK or Low. This is the state of the brake fluid level.
BPP Signal	-	Released	The scan tool displays Applied or Released. This is the state of the brake pedal.
DRP Active	-	No	The scan tool displays Yes or No. This is the state of the dynamic rear proportioning (DRP).
DRP Disabled	-	No	The scan tool displays Yes or No. This is the state of the dynamic rear proportioning (DRP).
Engine Drag Control Failed	-	No	The scan tool displays Yes or No. The state of the engine drag control depends on the state of traction of the tires and engine RPM.
LF Wheel Speed Sensor	-	0 km/h (0 mph)	This displays km/h (mph). This is the current speed of the left front wheel speed sensor.
LF Inlet Solenoid Command	-	Off	The scan tool displays On or Off. On is displayed when the left front inlet valve solenoid is commanded on.
LF Outlet Solenoid Command	-	Off	The scan tool displays On or Off. On is displayed when the left front outlet valve solenoid is commanded on.
Panic Brake Assist Failed	-	No	The scan tool displays Yes or No. The state of the panic brake assist depends on the state of traction of the tires and engine RPM.
Pump Motor Command Voltage	-	Varies	This displays Volts. This is the voltage status of the EBCM pump motor command.
Requested Torque	-	Varies	The scan tool displays 0-10%. The scan tool displays the duty cycle of the Requested Torque PWM signal. The duty cycle of the signal is used to transmit how much engine torque the EBCM is requested.
RF Inlet Solenoid Command	-	Off	The scan tool displays On or Off. On is displayed when the right front inlet valve solenoid is commanded on.
RF Outlet Solenoid Command	-	Off	The scan tool displays On or Off. On is displayed when the right front outlet valve solenoid is commanded on.
RF Wheel Speed Sensor	-	0 km/h (0 mph)	This displays km/h (mph). This is the current speed of the right front wheel speed sensor.
Rear Inlet Solenoid Command	-	Off	The scan tool displays On or Off. On is displayed when the right rear inlet valve solenoid is commanded on.
Rear Outlet Solenoid Command	-	Off	The scan tool displays On or Off. On is displayed when the right rear outlet valve solenoid is commanded on.
Rear Wheel Speed Sensor	-	0 km/h (0 mph)	This displays km/h (mph). This is the calculated speed of the rear wheels from the ECM.
TCS Active	-	No	The scan tool displays Yes or No. This is the state of the traction control system (TCS).
TCS Failed	-	No	The scan tool displays Yes or No. This is the state of the traction control system (TCS).
