DTC B2611 Telescopic Position Sensor or Telescopic Motor Circuit Malfunction |
DESCRIPTION
The telescopic motor is operated by 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 of the steering column in the forward and backward directions and sends a signal to the multiplex tilt and telescopic ECU based on that sliding amount.DTC No.
