Inspection Procedure

WARNING: This page is about a different car, the 2008 Lexus LS 600hL. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Before performing the inspection, check that there are no problems related to the "CAN COMMUNICATION SYSTEM" and "LIN COMMUNICATION SYSTEM"
  1. READ VALUE USING INTELLIGENT TESTER OR TECHSTREAM 
    1. Using the intelligent tester or Techstream, read the Data List.

        Result Proceed to
        Entry function cancel is OFF A
        Entry function cancel is ON B

    B: PERFORM CANCELLATION OF ENTRY KEY CANCEL FUNCTION  (See CUSTOMIZE PARAMETERS  )

    A: Go to Next Step 

  2. CHECK WAVE ENVIRONMENT 
    1. Move the electrical key transmitter as described below and perform the operation inspection (see OPERATION CHECK  ).

      HINT:

      • When the electrical key transmitter is brought near the door outside handle or electrical key antenna, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      • The transmitting wave of the wireless function and entry function are the same, but the wave logic is different As a result, it is possible that only the wireless function or only the entry function is affected by wave interference.
    2. Bring the electrical key transmitter near the front door outside handle LH, 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.

    3. Bring the electrical key transmitter near the front door outside handle RH, and perform a front passenger 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.

    4. Bring the electrical key transmitter near the rear door outside handle LH, and perform a rear left 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.

    5. 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 may not possible.
    6. Bring the electrical key transmitter near the indoor electrical key oscillator (in center console), and perform a hybrid control system start check.
      NOTE: If the key is brought within 0.2 m (0.656 ft.) of the center console, communication may not possible.

    7. Bring the electrical key transmitter near the indoor electrical key oscillator (in rear seat cushion), and perform a hybrid control system start check.
      NOTE: If the key is brought within 0.2 m (0.656 ft.) of the rear seat cushion, communication may not possible.
    8. Bring the electrical key transmitter near the electrical key antenna (in rear bumper), and perform an entry luggage compartment open function check

      NOTE: If the key is brought within 0.2 m (0.656 ft.) of the rear bumper, communication may not possible.

      HINT:

      If the inspection result is that the problem only occurs in certain locations or times of day, the possibility of wave interference is high Also, added vehicle components may cause wave interference If installed, remove them and perform the operation check
