DESCRIPTION The telescopic
motor (steering column assembly) is operated by the power source voltage
supplied from the multiplex tilt and telescopic ECU and slides the
steering column assembly forward and backward. The telescopic position
sensor (Hall IC) in the telescopic motor (steering column assembly)
detects the sliding position of the steering column assembly in the
forward and backward directions and sends a signal to the multiplex tilt
and telescopic ECU based on that sliding amount. |
