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 makes the steering column tilt 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 angle.

A01637XE01

Tech Tips

Limit positions can be confirmed on the intelligent tester.

DTC No. 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

    OK

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


    1. A0162FRE01

      Disconnect the J28 connector from the multiplex tilt and telescopic ECU.

    2. Disconnect the J22 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
      J28-6 (VCI) - J22-4 (VCI) Always Below 1 Ω
      J28-7 (TIS) - J22-5 (TIS) Always Below 1 Ω
      J28-17 (E1) - J22-6 (E1) Always Below 1 Ω
      J28-6 (VCI) - Body ground Always 10 kΩ or higher
      J28-7 (TIS) - Body ground Always 10 kΩ or higher
      J28-17 (E1) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

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


    1. A015YJ0E01

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      J28-11 (GND) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. INSPECT MULTIPLEX TILT AND TELESCOPIC ECU (TIS TERMINAL VOLTAGE)


    1. A015ZQKE01

      Reconnect the J28 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 Condition Specified Condition
      J28-7 (TIS) - J28-17 (E1) Steering tilts up or tilts down 11 to 14 V (Pulse HI)
      Below 1 V (Pulse LOW)

    NG

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


    1. A0162FRE02

      Disconnect the J28 connector from the multiplex tilt and telescopic ECU.

    2. Disconnect the J22 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
      J28-10 (TIM+) - J22-1 (TIM+) Always Below 1 Ω
      J28-1 (TIM-) - J22-2 (TIM-) Always Below 1 Ω
      J28-10 (TIM+) - Body ground Always 10 kΩ or higher
      J28-1 (TIM-) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  7. INSPECT TILT MOTOR


    1. A015Z4ME11

      Connect a positive battery lead to terminal TIM+ and a negative battery lead to terminal TIM- of the tilt motor connector. Then confirm that the steering wheel tilts up.

      OK
      Steering wheel tilts up.

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