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.
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 displays0-5 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.
