POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM, Diagnostic DTC:B2610

DTC Code DTC Name
B2610 Tilt Position Sensor or Tilt Motor Circuit Malfunction

DESCRIPTION

The tilt motor is operated by the power source voltage supplied from the multiplex tilt and telescopic ECU and tilts the steering column up and down. The tilt position sensor (Hall IC) in the tilt motor detects the tilt angle of the steering column and sends a signal to the multiplex tilt and telescopic ECU based on that angle.

DTC No. Detection Item Trouble Area
B2610 Tilt operation stops within the operation range while operating.

  • TI & TE fuse

  • Tilt position sensor or tilt motor

  • Harness or connector

  • Multiplex tilt and telescopic ECU

INSPECTION PROCEDURE

Tech Tips

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

PROCEDURE


  1. PERFORM ACTIVE TEST USING GTS (TILT OPERATION)


    1. Turn the power switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the power switch on (IG).

    4. Turn the GTS on.

    5. Check that the steering wheel tilts up and down. Enter the following menus: Body Electrical / Tilt & Telescopic / Active Test.
