Position Sensor or Tilt Motor Circuit Malfunction; 2015 MY Tundra [08/2014 - ]
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.
