Scan Tool Data Definitions

ABS Active: The scan tool displays Yes or No. Indicates if Antilock Brake System (ABS) is currently active.
ABS Failed: The scan tool displays Yes or No. Indicates if the electronic brake control module (EBCM) disabled ABS due to a malfunction.
Battery Voltage: The scan tool displays 0-30 volts. The voltage measured between the modules battery positive voltage circuit and ground circuit.
BPP Signal: The scan tool displays the applied state of the brake pedal position sensor.
Brake Fluid Level Status: The scan tool displays if level is OK or Low.
Brake Pressure Sensor Input: The scan tool displays 0-5 volts. Voltage signal indicates the master cylinder hydraulic pressure applied to the system
Delivered Torque: The scan tool displays 0-100%. The duty cycle of the signal is used to transmit how much engine torque the engine control module (ECM) is delivering. Normal values are between 10-90 percent duty cycle. The signal is at low values (approximately 10 percent) at idle and at higher values under driving conditions.
DRP Active: The scan tool displays Yes or No. The active status of the dynamic rear proportioning (DRP).
DRP Disabled: The scan tool displays Yes or No. Indicates if the EBCM disabled DRP due to a malfunction.
Engine Drag Control Failed: The scan tool displays Yes or No. Indicates if the EBCM disabled EDC due to a malfunction.
Lateral Accelerometer Signal: The scan tool displays 0-5 volts. The lateral accelerometer signal from the lateral accelerometer sensor, roughly 2.5 volts equals 0 g lateral acceleration.
LF Inlet Valve Command: The scan tool displays the commanded state of the left front inlet valve solenoid.
LF Outlet Valve Command: The scan tool displays the commanded state of the left front outlet valve solenoid.
LF Wheel Speed: The scan tool displays 0-255 km/h (0-159 mph). The actual speed of the left front wheel.
LR Inlet Valve Command: The scan tool displays the commanded state of the left rear inlet valve solenoid.
LR Outlet Valve Command: The scan tool displays the commanded state of the left rear outlet valve solenoid.
LR Wheel Speed: The scan tool displays 0-255 km/h (0-159 mph). The actual speed of the left rear wheel.
Panic Brake Assist Failed: The scan tool displays Yes or No. Indicates if the EBCM disabled Panic Brake Assist due to a malfunction.
Pump Motor Commanded Voltage: The scan tool displays the voltage applied to the ABS pump motor
Requested Torque: The scan tool displays 0-100%. The duty cycle of the signal is used to transmit how much torque the EBCM is requesting the ECM to deliver. Normal values are between 10-90 percent duty cycle. The signal should be at 90 percent duty cycle when traction control is not active and at lower values (approximately 10 percent) when traction control is active.
RF Inlet Valve Command: The scan tool displays the commanded state of the left front inlet valve solenoid.
RF Outlet Valve Command: The scan tool displays the commanded state of the right front outlet valve solenoid.
RF Wheel Speed: The scan tool displays 0-255 km/h (0-159 mph). The actual speed of the right front wheel.
RR Inlet Valve Command: The scan tool displays the commanded state of the right rear inlet valve solenoid.
RR Outlet Valve Command: The scan tool displays the commanded state of the right rear outlet valve solenoid.
RR Wheel Speed: The scan tool displays 0-255 km/h (0-159 mph). The actual speed of the right rear wheel.
SWPS Signal 1: The scan tool displays 0-5 volts. The steering wheel position signal 1 input.
SWPS Signal 2: The scan tool displays 0-5 volts. The steering wheel position signal 2 input.
TCS Active: The scan tool displays Yes or No. Indicates if Traction Control System (TCS) is currently active.
TCS Failed: The scan tool displays if the EBCM is no longer able to perform traction control.
Torque Delivered Signal: The scan tool displays 0-100%. The duty cycle of the signal is used to transmit how much engine torque the ECM is delivering. Normal values are between 10-90 percent duty cycle. The signal is at low values (approximately 10 percent) at idle and at higher values under driving conditions.
Torque Request Signal: The scan tool displays 0-100%. The duty cycle of the signal is used to transmit how much torque the EBCM is requesting the ECM to deliver. Normal values are between 10-90 percent duty cycle. The signal should be at 90 percent duty cycle when traction control is not active and at lower values (approximately 10 percent) when traction control is active.
VSES Active: The scan tool displays Yes or No. Indicates if Vehicle Stability Enhancement System (VSES) is currently active.
VSES Failed: The scan tool displays Yes or No. Indicates if the EBCM disabled VSES due to a malfunction.
Yaw Rate Sensor: The scan tool displays 0-5 volts. The yaw rate signal from the yaw rate sensor, roughly 2.5 volts equals 0°/second yaw rate.
