Code B052B 2017 Chevrolet Silverado Description

The Assist Step Control (ASC) Module controls the running board actuators to extend or retract the running boards. Each actuator consists of an electric motor and a hall-effect switch. The module supplies a low reference and 10 V reference source voltage to the hall-effect switch. The assist step control module monitors the signal from the hall effect switch on the signal circuit. When the actuator shaft rotates, the hall-effect switch provides pulses to the assist step control module which uses the pulses as counts to determine the location of the assist steps. The assist step control module supplies the actuator motor with a 12 V control circuit and a ground control circuit. The assist step control module controls the direction of the actuator by changing the polarity of the control circuits.
