U1000 can comm
Description
Refer to LAN-7, "CAN COMMUNICATION SYSTEM : System Description".
Dtc logic
Dtc detection logic
Note:
U1000 can be set if a module harness was disconnected and reconnected, perhaps during a repair. Confirm that there are actual can diagnostic symptoms and a present dtc by performing the self diagnostic result procedure.
