The ABS Scan Tool Data Definitions contain a brief description of all the ABS/traction 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 - The scan tool displays if ABS warning indicator is currently being commanded ON.

Auto Learn Mode Active: The scan tool displays Yes or No - The scan tool displays if TIM is currently in learn mode. The EBCM will be in learn mode after replacement or after the reset switch is activated.

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.

Brake Temp Status: The scan tool displays Normal or Over Temp - The scan tool displays if the brake temperature is above the traction control thermal cutoff point. If brake temperatures are above the thermal cutoff point, Over Temp is displayed and traction control is temporarily suspended until the brake temperature cools below the cutoff. This feature is used to maintain braking effectiveness if the base braking system is required. Overly heated brakes could result in brake fade.

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

EBCM to PCM Requested Torque: The scan tool displays 0-100 percent - The scan tool displays the duty cycle of the Delivered Torque PWM signal. The duty cycle of the signal is used to transmit how much torque the EBCM is requesting the PCM to deliver. Normal values are between 10 and 90 percent duty cycle. The signal should be at 90 percent duty cycle when traction control is not active and at lower values (approximately 10 percent) when traction control is active.

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 Rotor Temperature: The scan tool displays -40 to 650°C or -40 to 1202°F - The scan tool displays the estimated temperature of the brake rotor.

LF 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.

Low Tire Pressure: The scan tool displays Yes or No - The scan tool displays whether or not the tires should be checked for proper air pressure.

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.

LR 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.

Monitor Mode 1: The scan tool displays Active or Inactive - TIM autolearn is partially complete and reduced tire pressure monitoring capability is available. Only a large pressure loss within a tire will set the TIM light during this mode.

Monitor Mode 2: The scan tool displays Active or Inactive - TIM autolearn is complete and full tire pressure monitoring capability is available during this mode.

PCM to EBCM Delivered Torque: The scan tool displays 0-100 percent - The scan tool displays the duty cycle of the Requested Torque PWM signal. The duty cycle of the signal is used to transmit how much engine torque the PCM is delivering. Normal values are between 10 and 90 percent duty cycle. The signal is at low values (approximately 10 percent) at idle and at higher values under driving conditions.

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

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

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.

RF Rotor Temperature: The scan tool displays -40 to 650°C or -40 to 1202°F - The scan tool displays the estimated temperature of the right front brake rotor.

RF 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.

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.
