Scan Tool Data Definitions
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 sideways 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 wether 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.
