COMPONENT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000004201664

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 independent). 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.

DTC Logic

INFOID:0000000004201665

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

NOTE:

If “DTC CONFIRMATION PROCEDURE” has been previously performed, always turn ignition switch OFF.

Then wait at least 10 seconds before performing the next test.

1.

CHECK DTC DETECTION

With CONSULT-III

1. Turn ignition switch ON.

2. Start engine and wait for at least 6 seconds.

3. Perform “SELF-DIAG RESULTS” mode for “TRANSMISSION”.

With GST

Follow the procedure “With CONSULT-III”.
Is “U1000 CAN COMM CIRCUIT” detected?

YES

>> Go to 

TM-123, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-42, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000004201666

1.

CHECK CAN COMMUNICATION CIRCUIT

With CONSULT-III

1. Turn ignition switch ON and start engine.

2. Perform “SELF-DIAG RESULTS” mode for “TRANSMISSION”.
Is “U1000 CAN COMM CIRCUIT” indicated?

YES

>> Go to LAN section. Refer to 

LAN-25, "CAN System Specification Chart"

.

NO

>> Check intermittent incident. Refer to 

GI-42, "Intermittent Incident"

.

Malfunction is detected when...

Possible cause

U1000

CAN COMM CIRCUIT

When TCM is not transmitting or receiving 
CAN communication signal for 2 seconds or 
more.

Harness or connectors
(CAN communication line is open or short-
ed.)
