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 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
- The scan tool displays Active/Inactive. The scan tool displays Active when the right front Outlet valve solenoid is commanded on.
RF Inlet Valve Command
- The scan tool displays Active/Inactive. The scan tool displays Active when the right front Inlet valve solenoid is commanded on.
RF 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).
RR 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).
RR Outlet Valve Command
- The scan tool displays Active/Inactive. The scan tool displays Active when the right front Inlet valve solenoid is commanded on.
RR Inlet Valve Command
- The scan tool displays Active/Inactive. The scan tool displays Active when the right front Inlet valve solenoid is commanded on.
SWPS Signal 1
- The scan tool displays 0-5 volts. The steering wheel position signal 1 input.
SWPS Signal 2
- The scan tool displays 0-5 volts. The steering wheel position signal 2 input.
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.
