CHAPTER 5
94 SmarTrax™ Calibration & Operation Manual
◦ Center Learning - When set to Active, the SmarTrax system automatically recalibrates the SPS/WAS
center position during operation to adjust for slight shifts in the sensor’s center position. Bypassing this
feature leaves the SPS/WAS center position at its current value.
NOTE: Refer to the Wheel Angle Sensor (WAS) Calibration - If Applicable section on page 80 for sensor
calibration information.
