INSPECTION PROCEDURE

Note

Before performing the inspection, check that there are no problems related to the "CAN COMMUNICATION SYSTEM" and "LIN COMMUNICATION SYSTEM".

PROCEDURE


  1. CHECK POWER DOOR LOCK OPERATION


    1. When the master switch assembly's door control switch is operated, check that the locked doors unlock Click here.

      OK
      Locked doors unlock.

    NG

    GO TO POWER DOOR LOCK CONTROL SYSTEM Click here

    OK

  2. READ VALUE USING INTELLIGENT TESTER (DOOR LOCK POSITION SWITCH)


    1. Using the intelligent tester, read the Data List Click here.

      Driver Door
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Lock Position SW Driver side door lock position switch signal / ON or OFF

      ON: Driver side door is unlocked

      OFF: Driver side door is locked

      		 -
      OK
      On intelligent tester screen, item changes between ON and OFF according to above chart.

    NG

    GO TO POWER DOOR LOCK CONTROL SYSTEM (Proceed to Only Driver Door LOCK/UNLOCK Functions do not Operate) Click here

    OK

  3. READ VALUE USING INTELLIGENT TESTER (OUTSIDE HANDLE TRIGGER SW, ENTRY SENSOR)


    1. Using the intelligent tester read the Data List Click here.

      Driver Door
      Tester Display Measurement Item/Display Normal Condition Diagnostic Note
      Outside Handle Trigger SW Driver side door outside handle lock switch / ON or OFF

      ON: Driver side door outside handle lock switch is pushed

    OK

  4. CHECK WAVE ENVIRONMENT


    1. A01H0JAE09

      Bring the electrical key transmitter near the driver door outside handle, and perform a driver door entry lock and unlock operation check.

      Note

      If the key is brought within 0.2 m (0.656 ft.) of the door handle, communication may not possible.

      Tech Tips


      • When the electrical key transmitter is brought near the driver door outside handle, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.

      • If the inspection result is that the operation check is normal, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

      • On opposite side for RHD vehicle.

      Result

  5. KEY DIAGNOSTIC MODE


    1. A01H0JAE08

      Diagnostic mode inspection door electrical key oscillator


      1. Connect the intelligent tester to the DLC3.

      2. Turn the power switch ON (IG).

      3. Turn the intelligent tester on.

      4. Enter the following menus:

        Select: Body Electrical / Entry&Start / Key Communication Check /Overhead + Driver Side.

      5. When the electrical key transmitter is in the position shown in the illustration, check that the wireless door lock buzzer sounds*.

        Tech Tips


        • If the buzzer sounds, it can be determined that the driver seat outside transmitter is operating normally.

        • *: For Europe and China, the wireless door lock buzzer does not sound.

        • On opposite side for RHD vehicle.

        OK
        Wireless door lock buzzer sounds
