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 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.
- 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.
