Scan Tool Data Definitions
Scan Tool Data Definitions
ABS Active
The scan tool displays the active status of the ABS.
Brake Fluid Level Switch
The scan tool displays the status of the brake fluid level.
Brake Pressure Sensor
The scan tool displays the master cylinder hydraulic pressure applied to the system.
Brake Pressure Sensor Input
The scan tool displays the pressure sensor signal voltage.
Brake Temp Status
The electronic brake control module (EBCM) calculates the brake rotor temperature. If the EBCM determines that the rotor temperature is too high, brake intervention traction control is temporarily inhibited.
DRP Active
The scan tool displays the active status of the dynamic rear proportioning (DRP)
DRP Disabled
The scan tool displays the functional status of the DRP.
Ignition Voltage Signal
The scan tool displays ignition voltage from 0 - 17 volts.
Initial Brake Apply Signal
The scan tool displays the applied state of the brake pedal.
Lateral Accelerometer Signal
The scan tool displays the sensor voltage output and lateral g force.
Left TCS Isolation Solenoid Command
The scan tool displays the status of the left traction control system (TCS) isolation solenoid.
Left TCS Prime Solenoid Command
The scan tool displays the status of the left TCS primary solenoid.
LF Wheel Speed
The scan tool displays the actual speed of the left front wheel.
LR Wheel Speed
The scan tool displays the actual speed of the left rear wheel.
Moderate Brake Apply Signal
The scan tool displays applied when the brake pedal is depressed firmly.
Pump Motor Relay Command
The scan tool displays the commanded state of the pump motor relay.
Pump Motor Relay Feedback Voltage
The scan tool displays the actual ON/OFF state of the pump motor relay.
Right TCS Isolation Solenoid Command
The scan tool displays the status of the right TCS isolation solenoid.
Left TCS Prime Solenoid Command
The scan tool displays the status of the left TCS primary solenoid.
RF Wheel Speed
The scan tool displays the actual speed of the right front wheel.
Rough Road Detected
The EBCM calculates the condition of the road surface. This information is sent to the powertrain control module (PCM) via serial data messages. The PCM uses this information for misfire detection.
RR Wheel Speed
The scan tool displays the actual speed of the right rear wheel.
Solenoid Relay Command
The scan tool displays the commanded state of the solenoid relay.
Steering Position Sensor
The scan tool displays the steering wheel position in degrees.
Stoplamp Pedal Switch
The scan tool displays the applied state of the brake pedal.
Stoplamp Pedal Switch Signal
The scan tool displays the brake pedal position (BPP) sensor voltage.
Switched Battery Voltage
The scan tool displays 0 - 17 volts. The level of the internal EBCM switched battery voltage available to the solenoid valves and pump motor.
SWPS Signal 1
The scan tool displays the voltage output of signal 1 of the steering wheel position sensor (SWPS).
SWPS Signal 2
The scan tool displays the voltage output of signal 2 of the SWPS.
TCS Active
The scan tool displays Yes or No. The active status of the TCS indicates if TCS is currently active.
TCS Active Indicator/Message
The scan tool displays Off or On. Indicates if the EBCM is commanding the Traction Engaged message to be displayed by the DIC.
TCS Active
The scan tool displays the active status of the TCS.
TCS Enabled
The scan tool displays the operating status of the TCS.
Traction Control Status
The scan tool displays the active status of the TCS.
Torque Request Signal
The scan tool displays the requested engine torque to perform traction control sent by the EBCM.
Vehicle Speed
The scan tool displays the vehicle speed.
VSES Active
The scan tool displays the active status of the vehicle stability enhancement system (VSES).
VSES Enabled
The scan tool displays the operating status of the VSES.
Yaw Rate Sensor
The scan tool displays vehicle yaw rate in degrees of vehicle rotation per second (°/sec).
Yaw Rate Signal
The scan tool displays the sensor signal voltage.
