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 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.

Tip:

Limit positions can be confirmed on the screen of the intelligent tester.

DTC Code Detection Condition Trouble Area
B2611 The telescopic operation stops within the operation range while operating.

  • Harness or connector

  • Telescopic position sensor or telescopic motor

    CHECK TELESCOPIC MOTOR


    1. A0156ADE06

      Disconnect connector A from the multiplex tilt and telescopic ECU.

    2. Apply 12 V battery voltage to the multiplex tilt and telescopic ECU connector. Then check the steering wheel telescopic operation.

      OK
      Measurement Condition Specified Condition

      12 V battery positive (+) lead → Terminal A-2 (TEM+)

      12 V battery negative (-) lead → Terminal A-6 (TEM-)

      		 The steering column contracts.

      12 V battery positive (+) lead → Terminal A-6 (TEM-)

      12 V battery negative (-) lead → Terminal A-2 (TEM+)

      		 The steering column extends.
