ON BOARD DIAGNOSTIC (OBD) SYSTEM
Diagnosis DescriptionINFOID:0000000003848943
DESCRIPTION
The CVT system has two self-diagnostic systems.
The first is the emission-related on board diagnostic system (OBD) performed by the TCM in combination with
the ECM. A malfunction is indicated by the MI (Malfunction Indicator) and is stored as a DTC in the ECM mem-
ory and in the TCM memory.
The second is the TCM original self-diagnosis performed by the TCM. A malfunction history is stored in the
TCM memory. The detected items are overlapped with OBD self-diagnostic items. For details, refer to TM-121,
"DTC Index".
OBD FUNCTION
The ECM provides emission-related on board diagnostic (OBD) functions for the CVT system. One function is
to receive a signal from the TCM used with OBD-related parts of the CVT system. The signal is sent to the
ECM when a malfunction occurs in the corresponding OBD-related part. The other function is to indicate a
diagnostic result by means of the MI (Malfunction Indicator) on the instrument panel. Sensors, 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 CVT system parts.
ONE OR TWO TRIP DETECTION LOGIC OF OBD
One Trip Detection Logic
If a malfunction is sensed during the first test drive, the MI illuminates and the ECM memory stores the mal-
function 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 does not illuminate. — 1st trip
If the same malfunction as that experienced during the first test drive is sensed during the second test drive,
the MI will illuminate. — 2nd trip
The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation.
OBD DIAGNOSTIC TROUBLE CODE (DTC)
How to Read DTC and 1st Trip DTC
DTC and 1st trip DTC can be read by the following methods.
( with CONSULT-III or GST) CONSULT-III or GST (Generic Scan Tool) Examples: P0705, P0720, etc.
These DTC are prescribed by ISO 15031-6.
(CONSULT-III 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
it occurred in the past and has returned to normal.
CONSULT-III can identify them as shown below, therefore, CONSULT-III (if available) is recom-
mended.
- DTC or 1st trip DTC of a malfunction is displayed in “Self-Diagnostic Results” mode for “ENGINE” with CON-
SULT-III. Time data indicates 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 conditions 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 that 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-
III or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-III screen, not on the GST.
For details, refer to EC-113, "
CONSULT-III Function".

ON BOARD DIAGNOSTIC (OBD) SYSTEM
Only one set of freeze frame data (either 1st trip freeze frame data or 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 fol-
lowing priorities to update the data.
Both 1st trip freeze frame data and freeze frame data (along with the DTC) are cleared when the ECM mem-
ory is erased.
How to Erase DTC
The diagnostic trouble code can be erased by CONSULT-III, GST or ECM DIAGNOSTIC TEST MODE as
described below.
-If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours.
-When erasing the DTC, using CONSULT-III 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 OBD. For details, refer to EC-389, "
DTCIndex".
-Diagnostic trouble codes (DTC)
-1st trip diagnostic trouble codes (1st trip DTC)
-Freeze frame data
-1st trip freeze frame data
-System readiness test (SRT) codes
-Test values
How to Erase DTC (With CONSULT-III)
The emission related diagnostic information in the TCM and ECM can be erased by selecting “ALL Erase” in
the “Description” of “FINAL CHECK” mode with CONSULT-III.
How to Erase DTC (With GST)
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10
seconds and then turn it ON (engine stopped) again.
2. Select Mode 4 with GST (Generic Scan Tool). For details, refer to EC-113, "
CONSULT-III Function".
MALFUNCTION INDICATOR (MI)
Description
The MI is located on the instrument panel.
1. The MI is turned ON when the ignition switch is turned ON with-
out the engine running. This is a bulb check.
If the MI is not turned ON, refer to EC-346, "
Component Func-
tion Check".
2. The MI is turned OFF when the engine is started.
If the MI remains ON, the on board diagnostic system has
detected an engine system malfunction.
