U1000 CAN COMM CIRCUIT

COMPONENT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000000988643

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 and CAN-L) 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

NOTE:
If “DTC CONFIRMATION PROCEDURE” has been previously performed, always turn ignition switch
OFF and wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.

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”. Refer to

TM-216, "CONSULT-III Function (TRANSMISSION)"

.

With GST

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

YES

>> Go to

TM-222, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to

GI-39, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000000988645

1.

CHECK CAN COMMUNICATION CIRCUIT

With CONSULT-III

1.

Turn ignition switch ON and start engine.

2.

Select “SELF-DIAG RESULTS”.

Is any malfunction of the “U1000 CAN COMM CIRCUIT” indicated?

YES

>> Go to LAN section. Refer to

LAN-55, "CAN System Specification Chart"

.

NO

>> Check intermittent incident. Refer to

GI-39, "Intermittent Incident"

.
