GM Service Manual Online
For 1990-2009 cars only
ABS Active: The scan tool displays Yes or No. The active status of the ABS. Indicates if ABS is currently active.

BPP Status: The scan tool displays Applied or Released. The state of the brake pedal position sensor.

Brake Temp Status: The scan tool displays Normal or Over Temp. The status of the brake temperature. Indicates if the brake temperature is above the traction control thermal cutoff point.

Delivered Torque: The scan tool displays 0-100%. The duty cycle of the delivered torque 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.

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.

Engine Speed: The scan tool displays 0-9,999 RPM. The crankshaft rotation speed.

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

Lateral Accelerometer Signal: The scan tool displays -1.2 to +1.2 g. The lateral acceleration from the lateral accelerometer signal.

Lateral Accelerometer Signal: The scan tool displays 0-5 volts. The voltage of the lateral accelerometer signal.

Left Front Wheel Speed Sensor: The scan tool displays 0 to 255 km/h (0 to 159 mph). The actual speed of the left front wheel.

Left Rear Wheel Speed Sensor: The scan tool displays 0 to 255 km/h (0 to 159 mph). The actual speed of the left rear wheel.

Pump Motor Relay: The scan tool displays Off or On. Indicates the commanded state of the pump motor control.

Requested Torque: The scan tool displays 0-100%. The duty cycle of the requested torque 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.

Right Front Wheel Speed Sensor: The scan tool displays 0-255 km/h (0-159 mph). The actual speed of the right front wheel.

Right Rear Wheel Speed Sensor: The scan tool displays 0-255 km/h (0 to 159 mph). The actual speed of the right rear wheel.

Rough Road Detected: The scan tool displays Yes or No. The EBCM calculation of the road surface, this information is sent to the PCM via serial data messages. The PCM uses this information for misfire detection.

Solenoid Relay: The scan tool displays Off or On. Indicates the commanded state of the system relay.

Steering Wheel Position Sensor: The scan tool displays -720 to +720 degrees. The angle that the steering wheel is turned in degrees.

Switched Battery Signal: 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 0-5 volts. The steering wheel position signal 1 input.

SWPS Signal 2: The scan tool displays 0-5 volts. The steering wheel position signal 2 input.

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

TCS Active Indicator: The scan tool displays Off or On. Indicates if the EBCM is commanding the Traction Engaged message to be displayed by the DIC.

TCS Enabled: The scan tool displays Yes or No. Indicates if the EBCM has enabled TCS.

TCS Off Indicator: The scan tool displays Off or On. Indicates if the EBCM is commanding the Traction indicator to be displayed.

Traction Control Status: The scan tool displays Active or Inactive. The active status of the TCS. Indicates if TCS is currently active.

Traction Ready Message Command: The scan tool displays Off or On. Indicates if the EBCM is commanding the Traction Ready message to be displayed by the DIC.

Vehicle Speed: The scan tool displays 0-255 km/h (0-159 mph). The vehicle speed from the average of all four wheel speeds.

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

VSES Enabled: The scan tool displays Yes or No. Indicates if the VSES is enabled.

Yaw Rate Signal: The scan tool displays -75 to 75°/second. The yaw rate of the yaw rate signal.

Yaw Rate Signal: The scan tool displays 0-5 volts. The yaw rate signal from the yaw rate sensor, roughly 2.5 volts equals 0°/second yaw rate.
