POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM, Diagnostic DTC:B2611

DTC Code DTC Name
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. Detection Item Trouble Area
B2611 Telescopic operation stops within the operation range while operating.

  • TI &TE fuse

  • Telescopic position sensor or telescopic motor

  • Harness or connector

  • Multiplex tilt and telescopic ECU

Tech Tips

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE


  1. PERFORM ACTIVE TEST USING GTS (TELESCO OPERATION)


    1. Turn the engine switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the engine switch on (IG).

    4. Turn the GTS on.

    5. Check that the steering column contracts and extends. Enter the following menus: Body Electrical / Tilt & Telescopic / Active Test.
