DESCRIPTION

These DTCs are stored if there is a malfunction in the CAN communication system connected to the clearance warning ECU assembly.

HINT:

If CAN communication system DTCs are stored, they may also be stored in other systems.

1.	CHECK DTC OUTPUT

(a) Using the GTS, check for DTCs according to the prompts on the screen.

HINT:

After turning the ignition switch from off to ON, wait 10 seconds or more before checking for DTCs.

(b) Clear the DTCs according to the screen on the GTS.

OK:

No DTCs are output.

HINT:

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 troubleshooting again, even though DTCs were not output when rechecking for DTCs.

USE SIMULATION METHOD TO CHECK
