Scan Tool Data Definitions

The Data Display function contains a list of ABS data parameters. A brief description of all ABS data parameters available on the scan tool are listed below. The list is arranged in alphabetical order.

ABS Active: The scan tool displays Yes or No - The scan tool displays Yes when the ABS is active. This scan tool displays No during normal vehicle operation.

ABS Relay Command: The scan tool displays On or Off - The scan tool displays On during vehicle operation. The EBCM commands the ABS relay On when Ignition positive voltage is present.

ABS Relay Feedback: The scan tool displays On or Off - The scan tool displays On during vehicle operation.

ABS Warning Lamp: The scan tool displays Off or On - The scan tool displays whether or not the ABS warning indicator is currently being commanded ON.

Brake Fluid Level: The scan tool displays Low or Normal - The scan tool displays if the brake fluid level is below the standard operating level.

Brake Switch Status: The scan tool displays Applied or Released - The scan tool displays the state of the brake switch.

DRP Active: The scan tool displays Yes or No - The scan tool displays Yes when the Dynamic Rear Proportioning (DRP) is active. This scan tool displays No during normal vehicle operation.

DRP Disabled: The scan tool displays Yes or No -The display indicates if the EBCM has disabled the Dynamic Rear Proportioning (DRP) due to a malfunction.

DRP Switched Battery Voltage: The scan tool displays 0-17 Volts - The display indicates the level of the internal EBCM switched battery voltage available to the Dynamic Rear Proportioning (DRP).

Ignition Voltage: The scan tool displays 0 - 17 Volts - The scan tool displays the level of ignition positive voltage at the EBCM.

Left Front Wheel Speed: The scan tool displays 0 - 255 km/h or 0 - 158 mph - The scan tool displays the actual speed of the left front wheel.

Left Rear Wheel Speed: The scan tool displays 0 - 255 km/h or 0 - 158 mph - The scan tool displays the actual speed of the left rear wheel.

LF Inlet Valve Solenoid: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the LF inlet solenoid valve.

LF Outlet Valve Solenoid: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the LF outlet solenoid valve.

LR Inlet Valve Solenoid: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the LR inlet solenoid valve.

LR Outlet Valve Solenoid: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the LR outlet solenoid valve.

Pump Motor Commanded State: The scan tool displays On or Off - The scan tool displays the commanded state of the pump motor.

Pump Motor Feedback State: The scan tool displays On or Off - The scan tool displays the actual state of the pump motor.

Right Front Wheel Speed: The scan tool displays 0 - 255 km/h or 0 - 158 mph - The scan tool displays the actual speed of the right front wheel.

Right Rear Wheel Speed: The scan tool displays 0 - 255 km/h or 0 - 158 mph - The scan tool displays the actual speed of the right rear wheel.

RF Inlet Valve Solenoid: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the RF inlet solenoid valve.

RF Outlet Valve Solenoid: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the RF outlet solenoid valve;

Rough Road Parameter: The scan tool displays 0 - 1g - The scan tool displays the EBCM calculation of the road surface roughness. This information is sent to the PCM over the class 2 serial data line. The PCM uses this information for misfire detection.

RR Inlet Valve Solenoid: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the RR inlet solenoid valve.

RR Outlet Valve Solenoid: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the RR outlet solenoid valve.

Switched Battery Voltage: The scan tool displays 0 - 17 Volts - The scan tool displays the level of the internal EBCM switched battery voltage available to the solenoid valves and pump motor.

Vehicle Speed: The scan tool displays 0 - 255 km/h or 0 - 158 mph - This parameter displays the vehicle speed. The Powertrain Control Module (PCM) receives reference pulses from the Vehicle Speed Sensor (VSS) and converts them into km/h or MPH for display.
