DESCRIPTION


DTC No.
DTC Detection Condition
Trouble Area
01-DC
*1
Transmission to component shown by sub-code failed (Detecting this DTC does not always mean actual failure).
If the same sub-code is stored in other components, check power source circuit and communication system of all components shown by sub-code

HINT:
*1: If the power switch is turned off after idling for 60 seconds, this DTC may be stored when the engine is started again.

NOTICE:
  1. Before starting troubleshooting, be sure to clear the DTCs stored due to the reason described in the HINT above. Then, check for DTCs and troubleshoot according to the output DTCs.
  2. The radio receiver assembly is the master unit.
  3. Be sure to clear and recheck for DTCs after the inspection is completed to confirm that no DTCs are output.


INSPECTION PROCEDURE

NOTICE:
Be sure to read Description before performing the following procedure.

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 DTC 01-DC is output for the other components.

      HINT:
      If DTC 01-DC is output for any other components, check if the same physical address is displayed.


      Result:

      Result
      		Proceed to
      DTC 01-DC is output and the same physical address is displayed
      		A
      DTC 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.
