Scan Tool Data Definitions - Variable Effort Steering (VES)
DataBattery Voltage: The scan tool displays the battery system voltage.
EVO Desired Current: This data is what the body control module is trying to achieve.
EVO Actual Current: This data is the actual value of the actuator.
EVO Command: This data is the state of the actuator measured in counts.
EVO Input Current: This is the current/voltage input to the controlling device of the actuator
EVOLO Feedback: This data is the monitored return voltage from the actuator to the BCM.
EVOHI Feedback: This data is the monitored output voltage from the BCM to the actuator.
Steering Wheel Position: This data is the position of the steering wheel measured in volts.
Steering Wheel Rate: This data is the speed at which the steering wheel is turned.
Vehicle Speed: This is the body control module measurement of the vehicle's speed from a discrete input from the Powertrain Control Module (PCM).
Special Functions
EVO PWM: This function gives the scan tool user the ability to command the EVO actuator ON and OFF
