DTC |
B2610 |
Tilt Position Sensor or Tilt Motor Circuit Malfunction |
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 outputs a signal to the CPU based on that tilt.
HINT:
Limit positions can be confirmed on the screen of the Techstream.
