cation plate. Refer to GI-40, “Identification Plate”.

●

*1: These numbers are prescribed by ISO 15031-5.

●

*2: When the fail-safe operation occurs, the MI illuminates.

●

Introduction

ECS0096U

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 MI (malfunction indicator) 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-37, "ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION"

EURO-OBD Function for A/T System

ECS0096V

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 MI (malfunction indicator) on the instrument panel. Sen-
sors, switches and solenoid valves are used as sensing elements.
The MI 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-OBD

ECS0096W

ONE TRIP DETECTION LOGIC

If a malfunction is sensed during the first test drive, the MI 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 MI 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 MI will illuminate. — Second Trip
A/T-related parts for which the MI 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)

ECS0096X

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 ISO 15031-5.
(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.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION

A sample of CONSULT-II display for DTC is shown in the following
page. DTC or 1st trip DTC of a malfunction is displayed in SELF
DIAGNOSIS mode for “ENGINE” with CONSULT-II. Time data indi-
cates how many times the vehicle was driven after the last detection
of a DTC.

If the DTC is being detected currently, the time data will be “0”.

If a 1st trip DTC is stored in the ECM, the time data will be “1t”.

Freeze Frame Data and 1st Trip Freeze Frame Data

The ECM has a memory function, which stores the driving condition such as fuel system status, calculated
load value, engine coolant temperature, short term fuel trim, long term fuel trim, engine speed and vehicle
speed at the moment the ECM detects a malfunction.
Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data,
and the data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II
or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For
detail, refer to

EC-116, "CONSULT-II Function"

(QG).

Only one set of freeze frame data (either 1st trip freeze frame data of freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MI on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM.
The ECM has the following priorities to update the data.

Both 1st trip freeze frame data and freeze frame data (along with the DTCs) are cleared when the ECM mem-
ory is erased.

HOW TO ERASE DTC

The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE as
described following.

●

If the battery terminal is disconnected, the diagnostic trouble code will be lost within 24 hours.

●

When you erase the DTC, using CONSULT-II or GST is easier and quicker than switching the mode
selector on the ECM.

The following emission-related diagnostic information is cleared from the ECM memory when erasing DTC
related to EURO-OBD. For details, refer to

HOW TO ERASE DTC (WITH CONSULT-II)

●

If a DTC is displayed for both ECM and TCM, it needs to be erased for both ECM and TCM.

If the ignition switch stays “ON” after repair work, be sure to turn ignition switch “OFF” once. Wait at least
5 seconds and then turn it “ON” (engine stopped) again.

Turn CONSULT-II “ON” and touch “A/T”.

Touch “SELF DIAGNOSIS”.

Touch “ERASE”. (The DTC in the TCM will be erased.) Then touch “BACK” twice.

Touch “ENGINE”.

Touch “SELF DIAGNOSIS”.
