U0101 CAN COMM CIRCUIT

U0101 CAN COMM CIRCUIT

DTC Description

INFOID:0000000009418245

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 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 CAN 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 DETECTION LOGIC

POSSIBLE CAUSE

CAN communication line between TCM and ECM

FAIL-SAFE

Not applicable

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

>> Proceed to 

EC-140, "Diagnosis Procedure"

.

NO-1 >> To check malfunction symptom before repair: Refer to 

LAN-15, "Trouble Diagnosis Flow Chart"

.

NO-2 >> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000009418246

Perform the trouble diagnosis for CAN communication system. Refer to
