DESCRIPTION The tilt motor
(steering column assembly) is operated by the power source voltage
supplied from the multiplex tilt and telescopic ECU and tilts the
steering column up and down. The tilt position sensor (Hall IC) in the
tilt motor (steering column assembly) detects the tilt angle of the
steering column assembly and sends a signal to the multiplex tilt and
telescopic ECU based on that angle. |
DTC Code | Detection Condition |
