Scan Tool Data Definitions

The ABS scan tool data definitions contain a brief description of all ABS related parameters available on the scan tool. The parameters available on the scan tool are listed below in alphanumeric order.

4WD Status: The scan tool displays if the vehicle is in 2 wheel drive or 4 wheel drive.
ABS Active: The scan tool displays if the ABS system is performing antilock braking.
ABS Lamp Command: The scan tool displays the commanded state of the ABS warning indicator.
ABS Pump Motor: The scan tool displays On/Off. The scan tool displays On when the ABS pump motor is commanded on.
ABS Relay Command: The scan tool displays the commanded state of the ABS system relay.
ABS Stop State: The scan tool displays if the ABS system is performing antilock braking.
Accum. Pressure Sensor: The scan tool displays brake fluid pressure stored in the accumulator.
Analog Steering Position Sensor: The scan tool displays the analog steering position angle in degrees.
Battery Voltage: The scan tool displays the approximate voltage supplied by the battery and charging system.
Brake Fluid Level: The scan tool displays if the brake fluid is Low or OK.
Brake Switch Status: The scan tool displays the state of the brake switch.
Brake Warning Lamp Command: The scan tool displays ON when the EBCM requests illumination of the brake warning indicator.
Delivered Torque: The scan tool displays between 11% and 90%. The PCM provides the percentage of engine torque that is currently applied to the wheels. The lower the percentage the less torque applied to the wheels.
Digital Steering Position Sensor: The scan tool displays the digital steering position angle in degrees.
Lateral Accelerometer Input: The scan tool displays the sidways acceleration of the vehicle in meters per second (m/s) or feet per second (ft/s).
Left Front Wheel Speed: The scan tool displays the actual speed of the left front wheel.
Left Rear Wheel Speed: The scan tool displays the actual speed of the left rear wheel.
LF Dump Valve Command: The scan tool displays the commanded state of the left front dump valve solenoid.
LF Iso. Valve Command: The scan tool displays the commanded state of the left front isolation valve solenoid.
LR Dump Valve Command: The scan tool displays the commanded state of the left rear dump valve solenoid.
LR Iso. Valve Command: The scan tool displays the commanded state of the left front isolation valve solenoid.
Longitudinal Accelerometer Sensor Signal: The scan tool displays the longitudinal accelerometer sensor signal voltage.
Master Cylinder Pressure Sensor Input: The scan tool displays the hydraulic brake pressure applied by the master cylinder.
Requested Torque: The scan tool displays between 11% and 90%. The PCM provides the percentage of engine torque that is currently applied to the wheels. The lower the percentage the less torque applied to the wheels.
Reverse Switch: The scan tool displays ON when the transmission gear selector is in reverse.
Right Front Wheel Speed: The scan tool displays the actual speed of the left front wheel.
Right Rear Wheel Speed: The scan tool displays the actual speed of the left rear wheel.
RF Dump Valve Command: The scan tool displays the commanded state of the left front dump valve solenoid.
RF Dump Valve Command: The scan tool displays On/Off. The scan tool displays On when the right front dump valve solenoid is commanded on.
RF Iso. Valve Command: The scan tool displays the commanded state of the left front isolation valve solenoid.
RR Dump Valve Command: The scan tool displays the commanded state of the left rear dump valve solenoid.
RR Iso. Valve Command: The scan tool displays the commanded state of the left front isolation valve solenoid.
Stability System Active: The scan tool displays the active status of the vehicle stability enhancement system (VSES).
Stability System Enabled: The scan tool displays the operating status of the VSES.
System Configuration: The scan tool displays the configuration of the EBCM.
System Voltage: The scan tool displays the approximate voltage supplied by the battery and charging system.
TCS Status/EBCM -TCS Active: The scan tool displays Yes if the EBCM is requesting torque reduction from the PCM.
TCS Status/PCM -TCS Active: The scan tool displays Yes if the PCM is reducing engine torque during a traction control event.
Traction Control Equipped: The scan to displays if the vehicle is equipped with traction control.
Traction Control Switch: The scan tool displays the status of the traction control switch that is reported by the BCM.
Transmission Type: The scan too displays whether the vehicle is equipped with a manual or automatic transmission.
VSES Control Switch: The scan tool displays if the enabled/disabled status of the VSES system requested by the BCM/traction switch. VSES can be disabled by use of the traction switch.
VSES Equipped: The scan tool displays if the vehicle is equipped with VSES.
Yaw Rate Sensor Input: The scan tool displays the degrees of vehicle rotation (yaw rate) per second.
