Inspection Procedure

NOTE: Be sure to read the Description before performing the following procedures.
  1. CHECK FOR DTC OF OTHER COMPONENTS 
    1. Check if the component shown by the sub-code is displayed in the check result of the other components.
      1. Check if "01-DC" is output for the other components.
      2. If "01 -DC" is output for any other components, check if the same physical address is displayed.

        HINT:

        For the list of the components shown by sub-codes, refer to the table in the step below.

        Result 

        RESULT REFERENCE

        Result Proceed to
        "01-DC" is not output or the same physical address is not displayed A
        "01-DC" is output and the same physical address is displayed B

    B:  Go to step  4

    A: Go to next Step 

  2. CLEAR DTC 
    1. Clear the DTCs (See DTC CHECK / CLEAR  ).

      HINT:

      If "01-DC" is output for only one component, this may not indicate a malfunction.

  3. RECHECK FOR DTC 
    1. Recheck for DTCs and check if the same trouble code is output.

      OK: No DTC is output. 

      Result 

      RESULT REFERENCE

      Result Proceed to
      OK A
      NG (w/ Navigation System) B
      NG (w/o Navigation System) C

    B:  Go to step  6

    C:  Go to step  7

    A: USE SIMULATION METHOD TO CHECK  (See ELECTRONIC CIRCUIT INSPECTION PROCEDURE )

  4. IDENTIFY COMPONENT WHICH HAS STORED THIS CODE 
    1. Enter the diagnostic mode.
    2. Press the "LAN Mon" switch to change to "LAN Monitor" mode.
    3. Identify the component which has stored this code.
