HINT:

When 2 or more DTCs starting with "U" are output simultaneously, inspect the connectors and wire harnesses of each ECU.

1.	CHECK DTC OUTPUT

(a) Clear the DTCs

(b) Check for CAN communication system DTCs

Result	Proceed to
No CAN communication system DTCs are output	A
CAN communication system DTCs are output	B

USE SIMULATION METHOD TO CHECK
