DESCRIPTION
The tilt motor 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 detects the tilt angle of the steering column and sends a signal to the multiplex tilt and telescopic ECU based on that angle.
HINT:
Limit positions can be confirmed on the Techstream.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
---|---|---|---|
B2610 | Tilt Position Sensor or Tilt Motor Circuit Malfunction | Tilt operation stops within the operation range while operating. |
