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
1.
Turn ignition switch ON. (Do not start engine.)
2.
Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3.
Start engine and wait for at least 6 seconds.
