Diagnostic Procedure Without CONSULT-II
NCS000C7
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to
EC-133, "Generic Scan Tool (GST) Function"
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to
EC-62, "Malfunction Indicator Lamp (MIL)"
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
As a method for locating the suspect circuit, when the self-diagnostics start signal is input, the memory for the
malfunction location is output and the A/T CHECK indicator lamp flashes to display the corresponding DTC.
Operation Procedure
1.
CHECK A/T CHECK INDICATOR LAMP
1.
Start the engine with selector lever in “P” position. Warm engine to normal operating temperature.
2.
Turn ignition switch ON and OFF at least twice, then leave it in the OFF position.

Judgment Self-diagnosis Code
If there is a malfunction, the lamp lights up for the time corresponding to the suspect circuit.
Erase Self-diagnosis
●
In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.
●
However, this information is erased by turning ignition switch OFF after performing self-diagnostics or by
erasing the memory using the CONSULT-II.

DTC U1000 CAN COMMUNICATION LINE
DTC U1000 CAN COMMUNICATION LINE
PFP:23710
Description
NCS000C8
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
NCS000C9
●
This is an OBD-II self-diagnostic item.
●
Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-II or 17th judgment flicker without
CONSULT-II is detected when TCM cannot communicate to other control units.
Possible Cause
NCS000CA
Harness or connector
(CAN communication line is open or shorted.)
DTC Confirmation Procedure
NCS000CB
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.
WITH CONSULT-II
1.
Turn ignition switch ON.
2.
Select “ECU INPUT SIGNALS” or “MAIN SIGNALS” in “DATA
MONITOR” mode for “A/T” with CONSULT-II.
3.
Start engine and wait for at least 6 seconds.
4.
If DTC is detected, go to
AT-100, "Diagnostic Procedure"
WITH GST
Follow the procedure “WITH CONSULT-II”.
