U0140 LOST COMMUNICATION (BCM)

Description

INFOID:0000000009019653

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 speed and excellent malfunction detection ability.

Many electronic control units are equipped onto a vehicle, and each control unit shares information and links

with other control units during operation (not independently). In CAN communication, control units are con-

nected 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.

1.

CONTROL UNIT CHECK 

Check the number of control units replaced before “U0300” is detected. 
Is one control unit replaced? 

YES

>> The specification of the control unit replaced may be incorrect. Check the part number and the

specification. 

NO

>> GO TO 2.

2.

CONTROL UNIT CHECK

With CONSULT

1. Remove one of the control unit replaced. 

2. Assemble the old control unit before replacement. 

3. Turn ignition switch ON, and wait for 2 seconds or more.

4. Select “Self Diagnostic Results” in “TRANSMISSION”.
Is “U0300”detected?

YES

>> Turn OFF the ignition switch and check other control units in the same manner. 

NO

>> The specification of the control unit removed may be incorrect. Check the part number and the

specification.
