Tech Tips

When DTC U0123, U0124 and/or U0126 is output together with DTC C1436, inspect and repair the trouble areas indicated by DTC U0123, U0124 and/or U0126 first Click here.

PROCEDURE


  1. READ VALUE USING GTS (YAW RATE SENSOR)


    1. Turn the ignition switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON.

    4. Turn the GTS on.

    5. Enter the following menus: Chassis / ABS/VSC/TRC / Data List.

      ABS/VSC/TRC
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Yaw Rate Sensor Yaw rate and acceleration sensor 1 reading/ Min.: -128°/s, Max.: 127°/s

      Vehicle stationary: 0°/s

      Right turn: -128 to 0°/s

      Left turn: 0 to 127°/s

      		 -

    6. Check that the yaw rate and acceleration sensor (airbag sensor assembly) output value is displayed on the GTS.

  2. CHECK AIRBAG SENSOR ASSEMBLY INSTALLATION


    1. Turn the ignition switch off.

    2. Check that the yaw rate and acceleration sensor (airbag sensor assembly) is installed properly Click here.

      OK
      The sensor is tightened to the specified torque.
      The sensor is not installed at an angle.

    OK
