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.

ABS Active

The scan tool displays Yes/No. The scan tool displays No when a when not active.

ABS Failed

The scan tool displays On/Off. The scan tool displays On when a when the ABS Failed.

Battery Voltage

The scan tool displays 0-30 volts. The voltage measured between the modules battery positive voltage circuit and ground circuit.

Brake Fluid Level Status

The scan tool displays OK/Low The scan tool indicates Low when the brake fluid sensor detects fluid lose.

Brake Pressure Sensor Input

The scan tool displays 0-5 volts. Voltage signal indicates the master cylinder hydraulic pressure applied to the system

BPP Signal

The scan tool will display Released/Applied depending on the state of the brake pedal position.

Battery Voltage Signal

The scan tool will display Voltage depending on the state of the battery and charging system.

Delivered Torque

The scan tool displays 25-95%. The scan tool displays 25% when the powertrain control module (PCM) is providing the minimum percentage of available torque in an attempt to eliminate wheel slip.

DRP Active

The scan tool will display Yes/No depending on the state of the DRP.

DRP Disabled

The scan tool will display Yes/No depending on the state of the DRP.

Engine Drag Control Failed

The scan tool displays No or Yes. The scan tool will display Yes when the ED is active and No during normal vehicle operation.

Lateral Accelerometer Signal

The scan tool displays 0-5 volts. The lateral accelerometer signal from the lateral accelerometer sensor, roughly 2.5 volts equals 0 g lateral acceleration.

LF Wheel Speed Sensor

The scan tool displays 0-327 km/h (0-204 mph). The scan tool displays 0 km/h (0 mph) when the vehicle is not moving or is moving at speeds less than or equal to 0 km/h (0 mph).

LR Wheel Speed Sensor

The scan tool displays 0-327 km/h (0-204 mph). The scan tool displays 0 km/h (0 mph) when the vehicle is not moving or is moving at speeds less than or equal to 0 km/h (0 mph).

LF Outlet Valve Command

The scan tool displays Active/Inactive. The scan tool displays Active when the left front Outlet valve solenoid is commanded on.

LR Outlet Valve Command

The scan tool displays Active/Inactive. The scan tool displays Active when the left front Outlet valve solenoid is commanded on.

Panic Brake Assist Failed

The scan tool displays No/Yes. The scan tool displays No when the Panic brake Assist functions properly.

Pump Motor Command Voltage

The scan tool displays battery voltage when the pump motor is commanded on.

Requested Torque

The scan tool displays 40-95%. The scan tool displays 40% when the electronic brake control module (EBCM) requests the minimum percentage of available torque in an attempt to eliminate wheel slip.

RF Outlet Valve Command

TCS Active

The scan tool displays Yes or No. The scan tool displays Yes if the TCS indicator is currently being commanded ON.

TCS Failed

The scan tool displays Yes/No. The scan tool displays Yes when the TCS will not engage caused from a malfunction.

VSES Active

The scan tool displays Yes or No. Indicates if Vehicle Stability Enhancement System (VSES) is currently active.

VSES Failed

The scan tool displays Yes or No. Indicates if the EBCM disabled VSES due to a malfunction.

Yaw Rate Sensor

The scan tool displays 0-5 volts. The yaw rate signal from the yaw rate sensor, roughly 2.5 volts equals 0°/second yaw rate.
