For 1990-2009 cars only
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 represents 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: 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: --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.
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.
