U0140 CAN COMM CIRCUIT
DescriptionINFOID:0000000006141009
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication s
peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch ON and wait at least 3 seconds.
2. Check DTC.
Is DTC detected?
YES >> EC-131, "Diagnosis Procedure".
NO >> INSPECTION END
DTC No. Trouble diagnosis name DTC detecting conditionPossible cause
U0140 Lost communication with
BCM When ECM is not transmitting or receiving CAN
communication signal of OBD (emission related
diagnosis) with BCM for 2 seconds or more. • CAN communication line between
BCM and ECM
(CAN communication line is open or
shorted)
