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".

Engine Brake Adjustment
CAUTION:
Mode of “+1”“0”“−1”“−2”“OFF” can be selected by touching “UP”or “DOWN” on CONSULT-III screen.
However, do not select a mode other than “0” and “OFF”. Selecting “+1” or “−1” or “–2” may cause
irregular driveability.
Check CVT Fluid Deterioration Date
CAUTION:
Touch “CLEAR” after changing CVT fluid, and then erase “CVTF DETERIORATION DATE”.

Diagnostic test mode Function
Work Support This mode enables a technician to adjust some devices faster and more accurately.
Self-Diagnostic Results Retrieve DTC from ECU and display diagnostic items.
Data Monitor Monitor the input/output signal of the control unit in real time.
CAN Diagnosis This mode displays a network diagnosis result about CAN by a diagram.
CAN Diagnostic Support Monitor It monitors the status of CAN communication.
Function TestThis mode can show results of self-diagnosis of ECU with either “OK” or “NG”. For en-
gine, more practical tests regarding sensors/switches and/or actuators are available.
ECU Identification Display the ECU identification number (part number etc.) of the selected system.
Special Function Other results or histories, etc. that are recorded in ECU are displayed.
Item name Description
ENGINE BRAKE ADJ. The engine brake level setting can be canceled.
CONFORM CVTF DETERIORTN The CVT fluid deterioration level can be checked.
“ENGINE BRAKE LEVEL”
0 : Initial set value (Engine brake level control is activated)
OFF : Engine brake level control is deactivated.
“CVTF DETERIORATION DATE”
More than 210000 : It is necessary to change CVT fluid.
Less than 210000 : It is not necessary to change CVT fluid.
