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 next step.

        Result 

    RESULT REFERENCE

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

    B:  Go to step  4

    A: Go to Next Step 

  2. 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.

    COMPONENT SPECIFICATION

    Component Proceed To
    Radio receiver (AUDIO) Radio receiver communication error (See RADIO RECEIVER COMMUNICATION ERROR  )
    Stereo component amplifier (DSP-AMP) Stereo component amplifier communication error (See STEREO COMPONENT AMPLIFIER COMMUNICATION ERROR  )
    Multi-display (EMV) Multi-display communication error (See MULTI-DISPLAY COMMUNICATION ERROR  )
    Navigation ECU (NAVI) Navigation ECU communication error (See NAVIGATION ECU COMMUNICATION ERROR  )
    Television display (RSE) Television display communication error (See TELEVISION DISPLAY ASSEMBLY COMMUNICATION ERROR  )

    NEXT: END 

  4. 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.

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

      OK: No DTC is output. 

    NG: Go to step 6 

    OK: END 

  6. CHECK COMPONENT WHICH HAS STORED THIS CODE 
    1. Select the component which has stored this code.
