    2.CUSTOMER PROBLEM ANALYSIS

      HINT:
      1. In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
      2. Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.
      3. The following 5 items are important points in the problem analysis:

      What
      		Vehicle model, system name
      When
      		Date, time, occurrence frequency
      Where
      		Road conditions
      Under what conditions?
      		Running conditions, driving conditions, weather conditions
      How did it happen?
      		Problem symptoms

    4.INSPECT COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM (CAN)*

    1. Use the intelligent tester to check if the CAN communication system (CAN) is functioning normally.

      Result:
      Result
      		Proceed to
      ECU connected, communication line is normal.
      		A
      ECU connected, communication line is malfunctioning (for LHD).
      		B
      ECU connected, communication line is malfunctioning (for RHD).
      		C


    		B.
    GO TO CAN COMMUNICATION SYSTEM (for LHD) (CAMRY_ACV40 RM000000WI605LX.html)

    		C.
    GO TO CAN COMMUNICATION SYSTEM (for RHD) (CAMRY_ACV40 RM000000WI605KX.html)
    A


    5.INSPECT COMMUNICATION FUNCTION OF LIN COMMUNICATION SYSTEM (LIN)*

    1. Use the intelligent tester to check if the LIN communication system (LIN) is functioning normally (CAMRY_ACV40 RM000002XHS00KX.html).

      Result:
      Result
      		Proceed to
      LIN DTC is not output.
      		A
      LIN DTC is output.
      		B


    		B.
    GO TO DIAGNOSTIC TROUBLE CODE CHART (CAMRY_ACV40 RM000003DEX008X.html)
    A


    6.CHECK FOR DTC*

    1. Check for DTCs and note any codes that are output.

    2. Clear the DTCs.

    3. Recheck for DTCs. Based on the DTCs output, try to cause the same steering lock system DTC, engine immobiliser system DTC, wireless door lock control system DTC or entry and start system (start function) DTC to be output by simulating the symptoms indicated by the DTCs.

      Result:

      Result
      		Proceed to
      DTC is not output.
      		A
      Steering lock system DTC is output.
      		B
      Engine immobiliser system DTC is output.
      		C
      Wireless door lock control system DTC is output.
      		D
      Entry and start system (start function) DTC is output.
      		E
