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 |
Tech Tips
*1: If the power switch is turned off after idling for 60 seconds, this DTC may be stored when the engine is started again.
Note
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.
The radio receiver assembly is the master unit.
Be sure to clear and recheck for the DTCs after the inspection is completed to confirm that no DTCs are output.
