Data
Battery 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

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
