The ABS Scan Tool Data Definitions contain a brief description of all the ABS scan tool parameters. This list is in alphanumeric 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 1 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. Indicates if the EBCM is commanding the ABS indicator ON.

BFC Option Config. No.: The scan tool displays 4 characters - The scan tool displays the BFC Option Configuration Number of the BCM.

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.

Configuration ID: The scan tool displays 6 characters - The scan tool displays the configuration ID number of the EBCM.

DE Base Part Number: The scan tool displays 4 characters - The scan tool displays the base part number of the EBCM.

DE Build Sequence Number: The scan tool displays 8 characters - The scan tool displays the build sequence number of the EBCM.

DE Calibration Part Number: The scan tool displays 4 characters - The scan tool displays the calibration number of the EBCM.

DE End Model Part Number: The scan tool displays 4 characters - The scan tool displays the end model part number of the EBCM.

DE ROM Part Number: The scan tool displays 4 characters - The scan tool displays the ROM part number of the EBCM.

DRP Active: The scan tool displays Yes or No. The active status of the DRP. Indicates if DRP is currently active.

DRP Disabled: The scan tool displays Yes or No. The failed status of the DRP. Indicates if the EBCM disabled 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 voltage at the EBCM.

Julian Date Code: The scan tool displays year/day - The scan tool displays the last digit of the year and the day of the year that the EBCM was built.

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.

LF Wheel Speed: The scan tool displays 0-255 km/h (0-158 mph) - The scan tool displays the actual speed of the left front wheel.
