INTRODUCTION TO CVT DIAGNOSIS
M1231212300015
The CVT can exhibit any of the following symptoms:
noise or vibration is generated, Transmission fluid
leaks, the vehicle does not move forward or back-
ward. The causes of these symptoms could come
from: Incorrect mounting, the Transmission fluid may
be low, or a component of the transaxle may be
faulty.
The following items are suspected as causes for the
INVECS-III troubles: malfunction of the TCM, the
sensors, the switches, the harness or connectors.
Gather information from customer.
Check the transmission fluid.
Verify complaint.
Replace or replenish the
transmission fluid.
Communication with the scan tool

CVT DIAGNOSTIC TROUBLESHOOTING STRATEGY
M1231207600010
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will find most CVT mal-
functions.
1. Gather as much information as possible about the
complaint from the customer.
2. Verify that the condition described by the
customer exists.
3. Check the vehicle for any CVT Diagnostic Trouble
Codes (DTCs).
4. If you can not verify the condition and there are no
DTCs, the malfunction is intermittent. For
information on how to cope with intermittent
malfunctions, refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
− How
to Cope with Intermittent Malfunction
5. If you can verify the condition but there are no
DTCs, or the system can not communicate with
scan tool, refer to the Symptom Chart
.
6. If there is a DTC, record the number of the code,
then erase the code from memory using scan tool.
7. Reconfirm the symptom with a Road Test.
8. If a DTC is set again, go to the Inspection Chart
for Diagnostic Trouble Codes.
9. If a DTC is not set again, the malfunction is
intermittent. For information on how to cope with
intermittent malfunctions, refer to GROUP 00,
How to Use Troubleshooting/Inspection Service
Points
− How to Cope with Intermittent
Malfunction
10.After repairs are completed, conduct a Road Test
duplicating the complaint conditions to confirm the
malfunction has been eliminated.
DIAGNOSTIC FUNCTION
M1231219000297
WARNING INDICATOR
When any malfunction occurs in the items related to the CVT
system, which are described below, the symbol (A) continues
being displayed in the information screen in the multi informa-
tion display.
Check if the diagnostic trouble code is set when the symbol (A)
continues being displayed in the information screen in the multi
information display.
NOTE: When the symbol (B) is displayed in the information
screen in the multi information display, the transmission fluid
temperature is high. (Symbol (B) is turned on when the fluid
temperature is approximately 140
°
C (284
°
F) or higher and
turned off automatically when the fluid temperature drops
below approximately 137
°
C (279
°
F).)
ON-BOARD DIAGNOSTICS
The transaxle control module (TCM) monitors its
input/output signals (some signals all the time and
others under specified conditions). When an irregular
signal is initially monitored, the TCM decides that a
malfunction has occurred and records the occur-
rence as a diagnostic trouble code. There are 33
diagnostic items. The diagnostic results can be read
with scan tool. Diagnostic trouble codes are kept in
memory by direct battery feed. The codes are
retained in memory even if the ignition switch is in
the "LOCK" (OFF) position. DTCs are not erased
even after the battery terminals and the TCM con-
nector are disconnected. In addition, the diagnostic
trouble code can also be erased by scan tool.
NOTE: If a sensor is disconnected when the ignition
switch is in the "ON" position, a diagnostic trouble
code is stored in memory. In this case, erase the
DTC using scan tool.
The 33 diagnostic items are displayed in numeric
order.
