DTC B2611: TELESCOPIC POSITION SENSOR OR TELESCOPIC MOTOR CIRCUIT
MALFUNCTION

DESCRIPTION

The telescopic motor is operated by the power source voltage supplied from the multiplex tilt and telescopic
ECU and slides the steering column forward and backward. The telescopic position sensor (Hall IC) in the
telescopic motor detects the sliding position in the forward and backward directions of the steering column and
outputs a signal to the multiplex tilt and telescopic ECU based on that sliding amount.
