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.

A01GN9AE01

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

INSPECTION PROCEDURE

PROCEDURE


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


    1. A01GKR2E01

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

    A01GKIWE01

    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
    OK
  3. INSPECT TILT MOTOR

    A01GIXDE02

    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.

    NG
    OK
  4. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - TILT POSITION SENSOR)

    A01GKIWE03

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


    1. A01GIBCE02

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


    1. A01GNQ2E01

      Reconnect the L34 connector to the multiplex tilt and telescopic ECU.

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

      Standard voltage
      Tester Connection Switch Condition Specified Condition
      L26-4 (VCI) - L26-6 (E1) Engine switch on (IG) 8 to 16 V
      L26-5 (TIS) - L26-6 (E1) Engine switch on (IG) 8 to 16 V

    NG
    OK
  7. CHECK TILT POSITION SENSOR


    1. A01GKYGE05

      Reconnect the L26 connector to the tilt motor.

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

      Standard voltage
      Tester Connection Condition Specified Condition
      L34-7 (TIS) - L34-17 (E1) Steering tilts up or tilts down 8 to 16 V (Pulse HI)
      Below 1 V (Pulse LOW)

    NG
    OK
