POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM, Diagnostic DTC:B2610

DTC Code DTC Name
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 sends a signal to the multiplex tilt and telescopic ECU based on that angle.
