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	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

   Component	Physical Address
   Stereo component amplifier	440
   "Bluetooth" handsfree module	19D
   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.

   HINT:

   The "Bluetooth" handsfree module is built into the radio receiver. If there is a problem between the "Bluetooth" handsfree module and radio receiver, replace the radio receiver.

   Component	Proceed to
   Stereo component amplifier	(See STEREO COMPONENT AMPLIFIER COMMUNICATION ERROR  )
   "Bluetooth" handsfree module	(See BLUETOOTH HANDSFREE MODULE COMMUNICATION ERROR  )
   Radio receiver	(See RADIO RECEIVER 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 code occurs again.

   OK: Malfunction disappears. 

NG: Go to step  3

OK: END
