PRECAUTIONS
●Do not perform bypass wire connections for the repair
parts.(The spliced wire will become separated and the charac-
teristics of twisted line will be lost.)
PrecautionsECS004Q2
●Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch OFF and disconnect negative
battery terminal. Failure to do so may damage the TCM.
Because battery voltage is applied to TCM even if ignition
switch is turned off.
●When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
●Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. (See page AT- 1 0 6 , "
TCM Terminals and Reference
Va l u e".)

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONPFP:00000
IntroductionECS004QH
The A/T system has two self-diagnostic systems.
The first is the emission-related on board diagnostic system (EURO-OBD) performed by the TCM in combina-
tion with the ECM. The malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC
in the ECM memory but not the TCM memory.
The second is the TCM original self-diagnosis indicated by the O/D OFF indicator lamp. The malfunction is
stored in the TCM memory. The detected items are overlapped with EURO-OBD self-diagnostic items. For
detail, refer to AT-42, "
SELF-DIAGNOSTIC RESULT TEST MODE" .
EURO-OBD Function for A/T SystemECS004QI
The ECM provides emission-related on board diagnostic (EURO-OBD) functions for the A/T system. One
function is to receive a signal from the TCM used with EURO-OBD-related parts of the A/T system. The signal
is sent to the ECM when a malfunction occurs in the corresponding EURO-OBD-related part. The other func-
tion is to indicate a diagnostic result by means of the MIL (malfunction indicator lamp) on the instrument panel.
Sensors, switches and solenoid valves are used as sensing elements.
The MIL automatically illuminates in One or Two Trip Detection Logic when a malfunction is sensed in relation
to A/T system parts.
One or Two Trip Detection Logic of EURO-OBDECS004QJ
ONE TRIP DETECTION LOGIC
If a malfunction is sensed during the first test drive, the MIL will illuminate and the malfunction will be stored in
the ECM memory as a DTC. The TCM is not provided with such a memory function.
TWO TRIP DETECTION LOGIC
When a malfunction is sensed during the first test drive, it is stored in the ECM memory as a 1st trip DTC
(diagnostic trouble code) or 1st trip freeze frame data. At this point, the MIL will not illuminate. — First Trip
If the same malfunction as that experienced during the first test drive is sensed during the second test drive,
the MIL will illuminate. — Second Trip
A/T-related parts for which the MIL illuminates during the first or second test drive are listed below.
The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation.
EURO-OBD Diagnostic Trouble Code (DTC)ECS004QK
HOW TO READ DTC AND 1ST TRIP DTC
DTC and 1st trip DTC can be read by the following methods.
( With CONSULT-II or GST) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0710,
P0720, P0725, etc.
These DTCs are prescribed by SAE J2012.
(CONSULT-II also displays the malfunctioning component or system.)
●1st trip DTC No. is the same as DTC No.
●Output of the diagnostic trouble code indicates that the indicated circuit has a malfunction. How-
ever, in case of the Mode II and GST they do not indicate whether the malfunction is still occurring
or occurred in the past and returned to normal.
CONSULT-II can identify them as shown below. Therefore, using CONSULT-II (if available) is rec-
ommended.
