Scan Tool Data Definitions

WARNING: This page is about a different car, the 2006 Chevrolet Monte Carlo and 2006 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.

The Antilock Brake System (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.

ABS Active: The scan tool displays if the ABS system is performing antilock braking.
ABS Failed: The scan tool displays the working state of the ABS system.
ABS Pump Motor: The scan tool displays On/Off. The scan tool displays On when the ABS pump motor is commanded on.
Battery Voltage Signal: The scan tool displays the approximate voltage supplied by the battery and charging system.
BPP Signal:: The scan tool displays the applied state of the brake pedal position sensor.
Brake Fluid Level Status: The scan tool displays if the brake fluid is Low or OK.
Delivered Torque: The scan tool displays between 11% and 90%. The powertrain control module (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.
DRP Active: The scan tool displays if the electronic brake control module (EBCM) is performing dynamic rear proportioning.
DRP Disabled: The scan tool displays if the EBCM is no longer able to perform dynamic rear proportioning.
Engine Drag Control Failed:: The scan tool displays if the EBCM is no longer able to perform engine drag control.
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 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.
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 front outlet valve solenoid.
Pump Motor Commanded Voltage: The scan tool displays the voltage applied to the ABS pump motor
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 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 On/Off. The scan tool displays On when the right front outlet valve solenoid is commanded on.
RR Inlet Valve Command: The scan tool displays the commanded state of the left rear inlet valve solenoid.
RR Outlet Valve Command: The scan tool displays the commanded state of the left front outlet valve solenoid.
TCS Active: The scan tool displays if the EBCM is requesting torque reduction from the PCM.
TCS Failed: The scan tool displays if the EBCM is no longer able to perform traction control.
