Scan Tool Data Definitions - Variable Effort Steering (VES)

8 Digit GM Part Number: Scan tool displays: part number - Display indicates the part number of the EBCM.
Analog Steer Sensor Voltage: Scan tool displays: Volts - Display indicates the position of the Steering Wheel Position Sensor by displaying the analog voltage, roughly 2.5 volts when the front wheels are pointed straight.
Calibration ID: Scan tool displays: number- Display indicates the 4 digit calibration ID of the EBCM.
DE Base Part Number: Scan tool displays: part number - Display indicates the base part number of the EBCM.
DE Build Sequence Number: Scan tool displays: number - Display indicates the number in order that the EBCM was built.
DE Calibration Part Number: Scan tool displays: part number - Display indicates the end model part number of the EBCM.
DE End Model Part Number: Scan tool displays: part number - Display indicates the end model part number of the EBCM.
DE ROM Part Number: Scan tool displays: part number - Display indicates the ROM part number of the EBCM.
Digital SWPS Index Pulse (without JL4): Scan tool displays: High/Low - Display indicates the SWPS index pulse state. The index pulse represent the SWPS original centered position when the sensor was installed.
Digital SWPS Bias Correction: Scan tool displays: degrees - Display indicates the amount of change in the SWPS digital centered position after the centering routine is complete.
Digital SWPS Phase A Pulse: Scan tool displays: High/Low - Display indicates the state of the Phase A pulse. The EBCM uses the state change from Phase A and Phase B to calculate the position of the front wheels. The EBCM can also determine the direction the front wheels are rotating. If Phase A changes state first the wheels are turning left, if Phase B changes state first the wheels are turning right.
Digital SWPS Phase B Pulse: Scan tool displays: High/Low - Display indicates the state of the Phase B pulse. The EBCM uses the state change from Phase A and Phase B to calculate the position of the front wheels. The EBCM can also determine the direction the front wheels are rotating. If Phase A changes state first the wheels are turning left, if Phase B changes state first the wheels are turning right.
Ignition Power: Scan tool displays: Volts - Display indicated the level of ignition voltage at the EBCM.
Julian Date Code: Scan tool displays: year/day - Display indicates the last digit of the year and the day of the year that the EBCM was built.
Magnasteer* Commanded Current: Scan tool displays: Amps - Display indicates the amount of current the EBCM is commanding to the Magnasteer* actuator.
Magnasteer* Failed: Scan tool displays YES/NO - Display indicates if Magnasteer* is inactive do to a malfunction.
Magnasteer* Feedback Current: Scan tool displays: Amps - Display indicates the actual current that was sent to the Magnasteer* actuator.
Manufacturing Shift Info.: Scan tool displays: shift - Display indicates the shift when the EBCM was built.
Manufacturing Site: Scan tool displays: location - Display indicates the location where the EBCM was built.
PROM ID: Scan tool displays: number - Display indicates the 4 digit PROM ID of the EBCM.
Steer Angle Centering Complete: Scan tool displays: Yes/No -Display indicates if the Steering Wheel Position Sensor centering routine that the EBCM runs each time the vehicle is driven is complete.
Vehicle Speed: Scan tool displays: km/h (mph) - Display shows vehicle speed from the average of all four wheel speeds.
