DTC Code DTC Name
B2611 Telescopic Position Sensor or Telescopic Motor Circuit Malfunction
Click here

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 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.

Tip:

Limit positions can be confirmed on the GTS.

DTC No. Detection Item DTC Detection Condition Trouble Area
B2611 Telescopic Position Sensor or Telescopic Motor Circuit Malfunction Telescopic operation stops within the operation range while operating.

  • Telescopic position sensor or telescopic motor

  • Harness or connector
