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 Two wheel drive/Four wheel drive. The scan tool displays Two wheel drive when the transfer case is shifted into two wheel drive.

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.

Battery Voltage
The scan tool displays the approximate voltage supplied by the battery and charging system.

Brake Switch Status
The scan tool displays the state of the brake switch.

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

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.

Low Trac: TCS Active
The scan tool displays if the TCS is performing traction control.

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

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.

TCS Requested
The scan tool displays Yes/No. The scan tool displays No when the driver has disabled the TCS by pressing the traction control switch.

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.

Steering Wheel Position
The scan tool displays the steering wheel position in degrees.

TCS Failed
The scan tool displays the working state of the TCS. If the TCS is disabled by a DTC or the powertrain control module (PCM) the scan tool will display yes.

TCS Requested
The scan tool displays the operating status of the TCS.

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.
