CONFORM CVTF DETERIORTN
The CVT fluid deterioration level can be checked.

DIAGNOSIS SYSTEM (TCM)
CAUTION:
Mode of “+1”, “0”, “
−
1”, “
−
2”, “OFF” can be selected by touching “UP” or “DOWN” on CONSULT
screen. However, do not select mode other than “0” and “OFF”. Selecting “+1” or “
−
1” or “
−
2” is
selected, that may cause irregular driveability.
Conform CVTF Deterioration
• Check CVT fluid deterioration level when driving under severe conditions.
• How to Erase CVT Fluid Deterioration Date
- Select “clear”.
Calibration Data
After replacing transaxle assembly, it is necessary to initialize ROM data of TCM. Checking calibration data
makes it possible to check that initialization is successful.

OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
EC-101, "GST (Generic Scan Tool)"
“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.

DTC/CIRCUIT DIAGNOSIS
U0100 LOST COMMUNICATION (ECM A)
Description
INFOID:0000000009948943
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 independently). 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.

DTC DETECTION LOGIC
DTC CONFIRMATION PROCEDURE
1.
PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
1.
Start the engine and wait for at least 5 seconds.
2.
Check DTC.
With GST
Follow the procedure “With CONSULT”.
Is “U0100” detected?
YES
>> Go to
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000009948945
For the diagnosis procedure, refer to

Lost Communication With
ECM/PCM A
When the ignition switch is ON, TCM is un-
able to receive the CAN communications
signal from ECM continuously for 2 sec-
onds or more.
• ECM
• Harness or connector
(CAN communication line is open or
shorted)
