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 COMPONENT CHART  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.

   Display	Component
   AUDIO H/U (190)	Radio receiver
   DSP-AMP (440)	Stereo component amplifier
   G/W(1C6)	Gateway ECU
   NAVI (178)	Navigation ECU
   EMV(110)	Multi-display
   CLOCK (1D6)	Clock assembly

   HINT:

   "NAVI" is the component which has stored this code in the example shown in the illustration.

1. Select the component which has stored this code.

   Component	Proceed to
   Gateway ECU (G/W)	GATEWAY ECU COMMUNICATION ERROR
   Radio receiver (AUDIO H/U)	RADIO RECEIVER COMMUNICATION ERROR
   Stereo component amplifier (DSP-AMP)	STEREO COMPONENT AMPLIFIER COMMUNICATION ERROR
   Navigation ECU (NAVI)	NAVIGATION ECU COMMUNICATION ERROR
   Multi-display (EMV)	MULTI-DISPLAY COMMUNICATION ERROR
   Clock assembly (1D6)	CLOCK 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
