DESCRIPTION
These DTCs are stored if there is a malfunction in the CAN communication system connected to the clearance warning ECU assembly.
Tech Tips
If CAN communication system DTCs are stored, they may also be stored in other systems.

PROCEDURE
CHECK DTC OUTPUT
Clear the DTCs.
Recheck for DTCs and check if the same DTC is output again.
| OK |
|---|
| No DTCs are output. |
Tech Tips
If CAN communication system DTCs are stored, they may also be stored in other systems.
If the CAN communication system has been inspected and repaired in other systems, the DTCs will not be output when rechecking for DTCs.
If these DTCs are output frequently, duplicate the conditions that caused the problem symptoms and perform the inspection again, even though DTCs were not output when rechecking for DTCs.
