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 outputs a signal to the CPU based on that tilt.

A01X93VE18

Tech Tips

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

DTC Code Detection Condition Trouble Area
B2610 The tilt operation stops within the operation range while operating.

  • Harness or connector

  • Tilt position sensor or tilt motor

  • Multiplex tilt and telescopic ECU

PROCEDURE


  1. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (TILT UP/DOWN)

    A01X72RE01
    *1 Up
    *2 Down

    1. Select the Active Test, use the intelligent tester to generate a control command, and then check that the steering wheel tilts up and down.

  2. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - TILT MOTOR)

    A01X2QZE02
    *a Rear view of wire harness connector: (to Multiplex Tilt and Telescopic ECU)
    *b Rear view of wire harness connector: (to Tilt Motor)

    1. Disconnect the E27 multiplex tilt and telescopic ECU connector.

    2. Disconnect the E17 tilt motor connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      E27-10 (TIM+) - E17-1 (TIM+) Always Below 1 Ω
      E27-1 (TIM-) - E17-2 (TIM-)
      E27-10 (TIM+) - Body ground Always 10 kΩ or higher
      E27-1 (TIM-) - Body ground

    NG

    OK

  3. INSPECT TILT MOTOR

    A01X360E09
    *1 Component without harness connected: (Tilt Motor)

    1. Apply 12 V battery voltage to the tilt motor connector. Then check the steering wheel tilt operation.

      OK
      Measurement Condition Specified Condition

      12 V battery positive (+) lead → Terminal E17-1 (TIM+)

      12 V battery negative (-) lead → Terminal E17-2 (TIM-)

      		 The steering wheel tilts up.

      12 V battery positive (+) lead → Terminal E17-2 (TIM-)

      12 V battery negative (-) lead → Terminal E17-1 (TIM+)

      		 The steering wheel tilts down.

    OK
