Data Display/Definitions

The Scan Tool Data Display/Definitions contains a brief description of all the ABS/ TCS/VSES data parameters. The menus available depend on the number and type of system on the vehicle and are listed below in alphanumeric order.

ABS DATA
TCS DATA
VSES DATA

ABS Active: The scan tool displays Yes or No. The scan tool will display Yes when the ABS is active and No during normal vehicle operation.
ABS Warning Lamp: The scan tool will display On or Off depending on the state of the ABS indicator.
Brake Switch: The scan tool will display Applied or Released depending on the state of the brake switch.
BPMV Pressure Sensor: The scan tool will display BAR/PSI depending on pressure applied to brake pedal.
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.
EBTCM to PCM Requested 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 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 a lower value approximately 10 percent when the traction control is active.
Engine Speed: The scan tool will display between 0 to 10200 RPM which is a digital tachometer display.
Ignition Voltage: The scan tool displays 0-17 Volts. The scan tool displays the level of ignition voltage at the EBCM.
Lateral Acceleration Sensor: The scan tool will display 0 g. The scan tool displays the lateral accelerometer signal received from the sensor.
LF Inlet Valve Solenoid Inactive: The scan tool will display Active or Inactive. The scan tool displays the commanded state of the LF inlet solenoid valve.
LF Outlet Valve Solenoid Inactive: The scan tool will display Active or Inactive. The scan tool displays the commanded state of the LF outlet solenoid valve.
LF TCS Isolation Solenoid: The scan tool will display Active/Inactive. This displays the commanded state of the solenoid valve.
LF TCS Prime Solenoid: The scan tool will display Active/Inactive. This displays the commanded of the solenoid valve.
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.
Low Traction Lamp: The scan tool will display On/Off. This will indicate the state of the LOW TRAC Indicator.
LR Inlet Valve Solenoid Inactive: The scan tool displays Active or Inactive. The scan tool displays the commanded state of the LR inlet solenoid valve.
LR Outlet Valve Solenoid Inactive: The scan tool displays Active or Inactive. The scan tool displays the commanded state of the LR outlet solenoid valve.
Motor Relay State: The scan tool display On /Off. This is the commanded state of the relay.
PCM to EBTCM Delivered 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 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.
RF Inlet Valve Solenoid Inactive: The scan tool displays Active or Inactive. The scan tool displays the commanded state of the RF inlet solenoid valve.
RF Outlet Valve Solenoid Inactive: The scan tool displays Active or Inactive. The scan tool displays the commanded state of the RF outlet solenoid valve.
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.
RF TCS Isolation Solenoid: The scan tool will display Active/Inactive. This will be the commanded state of the solenoid valve.
RF TCS Prime Solenoid: The scan tool will display Active/Inactive. This will be the commanded state of the solenoid valve.
RR Inlet Valve Solenoid Inactive: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the RR inlet solenoid valve.
RR Outlet Valve Solenoid Inactive: The scan tool displays Active or Inactive - The scan tool displays the commanded state of the RR outlet solenoid valve.
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.
Rough Road Parameters: The scan tool will display 0-g. The scan tool will display the EBCM calculation of the road surface roughness. This information is then sent to the PCM over the class 2 serial data line. This information is used by the PCM for misfire detection.
TCS Active: The scan tool displays Off or On. The scan tool displays On if the TCS indicator is currently being commanded ON.
TCS Switch State: The scan tool displays On/Off. The scan tool will display the state of the Traction Control Switch.
TCS Warning Lamp: The scan tool will display On or Off depending on the state of the TCS indicator.
Valve Relay State: The scan tool will display On/Off depending on the state of the VSES relay.
VSES Active: The scan tool will display YES/NO depending on the state of the Active Sensor.
VES Auto Learn Complete: The scan tool will display YES/NO depending if the VSES auto learn is completed.
VSES Failed: The scan tool will display YES/NO depending on the state of the VSES.
VES Malfunction: The scan tool displays YES/NO. The scan tool will display the state of the Malfunction Sensor.
VES Steering Angle Sensor: The scan tool displays -720 to approximately +720. The scan tool will display the signal received from the Steering Angle Sensor.
Yaw Rate Sensor: The scan tool displays 0.0°/sec. The scan tool displays the signal received from the yaw rate sensor.
