CHA
This is a square wave generated whenever there is movement of the Steer Request Encoder. Voltage varies as the encoder shaft rotates. The frequency varies directly with the speed the speed the steer wheel is spun by the operator. The CM uses the quadrature phase relationship between CH A & B to determine direction and speed of steering requested.
Not turning= 5V or 0V Turning= 2.2V
