Inspection Procedure

NOTE: Before performing the inspection, check that there are no problems related to the "CAN COMMUNICATION SYSTEM" and "LIN COMMUNICATION SYSTEM".
  1. CHECK POWER DOOR LOCK OPERATION 
    1. When the master switch's door control switch is operated, check that the locked doors unlock (see OPERATION CHECK  )

      OK: Locked doors unlock. 

    NG: GO TO POWER DOOR LOCK CONTROL SYSTEM 

    OK: Go to next Step 

  2. READ VALUE USING INTELLIGENT TESTER OR TECHSTREAM 
    1. Using the intelligent tester or Techstream, read the Data List (see DATA LIST / ACTIVE TEST  ).
      1. Intelligent tester

        RR-DOOR 

        DIAGNOSTIC NOTE NORMAL CONDITION CHART

        Tester Display Measurement Item/Display Normal Condition Diagnostic Note

        Tester Display Measurement Item/Display Normal Condition Diagnostic Note
        Entry Sensor Rear RH side door touch sensor / ON or OFF ON Rear side door sensor RH is touched
        OFF Rear side door sensor RH is not touched        		 -
        Outside Handle Trigger SW Rear RH side door outside handle lock switch / ON or OFF ON Rear side door outside handle lock switch RH is pushed
        OFF Rear side door outside handle lock switch RH is not pushed        		 -

    NG:  Go to step  13

    OK: Go to next Step 

  3. CHECK WAVE ENVIRONMENT 
    1. Bring the electrical key transmitter near the rear door outside handle RH, and perform a rear right 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 is not possible.

      HINT:

      • When the electrical key transmitter is brought near the rear right passenger 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
