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.

A001BKTE01

Tech Tips

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

DTC Code Detection Item Trouble Area
B2610 Tilt operation stops within the operation range while operating.

  • Wire 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)


    1. A001FPGE01
      *1 Up
      *2 Down

      Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG) and turn the intelligent tester on.

    3. Select "Tilt & Telescopic".

    4. Select "Tilt Operation", and perform the Active Test using the intelligent tester.

    5. Check that the steering wheel tilts up (down) when the Active Test is carried out.

      OK
      Steering wheel tilts up (down).

    OK

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

    A001AV2E03
    *1 Rear view of wire harness connector: (to Multiplex Tilt and Telescopic ECU)
    *2 Rear view of wire harness connector: (to Tilt Motor)

    1. Disconnect the L34 connector from the multiplex tilt and telescopic ECU.

    2. Disconnect the L26 connector from the tilt motor.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      L34-10 (TIM+) - L26-1 (TIM+) Always Below 1 Ω
      L34-1 (TIM-) - L26-2 (TIM-) Always Below 1 Ω
      L34-10 (TIM+) - Body ground Always 10 kΩ or higher
      L34-1 (TIM-) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. INSPECT TILT MOTOR

    A001C44E10
    *1 Component without harness connected: (Tilt Motor Connector)

    1. Connect the positive (+) battery terminal to terminal L26-1 (TIM+) and the negative (-) battery terminal to terminal L26-2 (TIM-) of the tilt motor connector. Then confirm that the steering wheel tilts up.

      OK
      The steering wheel tilts up.

    2. Connect the negative (-) battery terminal to terminal L26-1 (TIM+) and the positive (+) battery terminal to terminal L26-2 (TIM-) of the tilt motor connector. Then confirm that the steering wheel tilts down.

      OK
      The steering wheel tilts down.

    OK

    A001C8QE03
    *1 Rear view of wire harness connector: (to Multiplex Tilt and Telescopic ECU)
    *2 Rear view of wire harness connector: (to Tilt Motor)

    1. Disconnect the L34 connector from the multiplex tilt and telescopic ECU.

    2. Disconnect the L26 connector from the tilt motor.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      L34-6 (VCI) - L26-4 (VCI) Always Below 1 Ω
      L34-7 (TIS) - L26-5 (TIS) Always Below 1 Ω
      L34-17 (E1) - L26-6 (E1) Always Below 1 Ω
      L34-6 (VCI) - Body ground Always 10 kΩ or higher
      L34-7 (TIS) - Body ground Always 10 kΩ or higher
      L34-17 (E1) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  5. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - BODY GROUND)


    1. A0019ACE05
      *1 Rear view of wire harness connector: (to Multiplex Tilt and Telescopic ECU)

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

      Standard resistance
      Tester Connection Condition Specified Condition
      L34-11 (GND) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  6. CHECK MULTIPLEX TILT AND TELESCOPIC ECU (VCI, TIS TERMINAL VOLTAGE)


    1. A001CUZE03
      *1 Rear view of wire harness connector: (to Tilt Motor)
