Inspection Procedure

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 step 2.

      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 

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	Proceed to
   Navigation receiver assembly (AVN)	Navigation receiver assembly communication error (See NAVIGATION RECEIVER ASSEMBLY COMMUNICATION ERROR  )
   Television display assembly (Rr-TV)	Television display assembly communication error (See TELEVISION DISPLAY ASSEMBLY COMMUNICATION ERROR  )
   Stereo component amplifier (DSP-AMP)	Stereo component amplifier communication error (See STEREO COMPONENT AMPLIFIER COMMUNICATION ERROR  )

NEXT: END 

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

   HINT:

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

1. Recheck for DTCs and check if the same trouble occurs again.

   OK: Malfunction disappears. 

NG:  Go to step  3

OK: END
