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.

      Result 

      RESULT OF DTC OF OTHER COMPONENTS
      
      

      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

      HINT:

      For the list of the components shown by sub-codes, refer to the table in step 2.

B: Go to step  4

2. Press the preset switch "3" to change to "Detailed Information Mode".
3. Identify the component which has stored this code.

   Component Table: 

   COMPONENT/PHYSICAL ADDRESS
   
   

   Component	Physical address
   Stereo component amplifier	440
   Radio receiver	190

   HINT:

   • "440 (stereo component amplifier)" is the component which has stored this code in the example shown in the illustration.
   • For details of the DTC display, refer to "DTC CHECK / CLEAR " .

1. Select the component which has stored this code.

   Component Table: 

   COMPONENT WHICH HAS STORED THIS CODE
   
   

   Component	Proceed to
   Stereo component amplifier	STEREO COMPONENT AMPLIFIER COMMUNICATION ERROR
   Radio receiver	RADIO RECEIVER COMMUNICATION ERROR

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 code occurs again.

   OK: 

   Malfunction disappears. 

NG: Go to step  3

OK: END
