DESCRIPTION
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| 01-DC | Transmission to the component shown by the sub-code failed (Detecting this DTC does not always mean actual failure). | If the same sub-code is recorded in other components, check harness for power supply and communication system of all components shown by code |
Tech Tips
This code may be stored if the engine is started and idled for 60 seconds and then the ignition switch is turned to the start position again.
Note
Before starting troubleshooting, be sure to clear DTCs to clear codes stored due to the reasons described in 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 DTCs after the inspection is completed to confirm that no DTCs are output.
INSPECTION PROCEDURE
Note
Be sure to read Description before performing the following procedures.
PROCEDURE
CHECK FOR DTC OF OTHER COMPONENTS
Check if the component shown by the sub-code is displayed in the check result of the other components.
Check if "01-DC" is output for the other components.
If "01-DC" is output for any other components, check if the same physical address is displayed.
Tech Tips
For the list of the components shown by sub-codes, refer to the table in the next step.
| Result | Proceed to |
|---|---|
| "01-DC" is not output or the same physical address is not displayed | A |
| "01-DC" is output and the same physical address is displayed | B |
