DTC U1000 CAN COMMUNICATION LINE

Revision: 2004 November

DTC U1000 CAN COMMUNICATION LINE

PFP:23710

Description

ACS001TF

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.

On Board Diagnosis Logic

ACS001TG

●

This is an OBD-II self-diagnostic item.

●

Diagnostic trouble code “CAN COMM CIRCUIT” with CONSULT-II or U1000 without CONSULT-II is
detected when TCM cannot communicate to other control units.

Possible Cause

ACS001TH

Harness or connectors
(CAN communication line is open or shorted.)

DTC Confirmation Procedure

ACS001TI

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, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.

WITH CONSULT-II

Turn ignition switch ON. (Do not start engine.)

Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.

Start engine and wait for at least 6 seconds.

If DTC is detected, go to

CVT-73, "Diagnostic Procedure"

WITH GST

Follow the procedure “WITH CONSULT-II”.

ACS001TM

●

This is not an OBD-II self-diagnostic item.

●

Diagnostic trouble code “STARTER RELAY/CIRC” with CONSULT-II is detected when starter relay
switched “ON” other than at “P” or “N” position. (Or when switched “OFF” at “P” or “N” position).

Possible Cause

ACS001TN

●

Harness or connectors
(Starter relay and TCM circuit is open or shorted.)
