HINT:

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

PROCEDURE

1.

CHECK DTC OUTPUT

(a) Clear the DTCs

Body Electrical > Clearance Warning > Clear DTCs

(b) Check for CAN communication system DTCs

Body Electrical > Clearance Warning > Clear DTCs

(c) Recheck for DTCs.

Body Electrical > Clearance Warning > Trouble Codes

Result

Proceed to

No CAN communication system DTCs are output

A
