Fail-safe
INFOID:0000000007576445
The TCM has an electrical fail-safe mode. In this mode TCM is operator even if there is an error in a main
electronic control input/output signal circuit.
DESCRIPTION
When a malfunction is detected in each sensor, switch, solenoid or others, this function provides control to
minimize reduction of drivability so that durability of transmission assembly can be acquired.

INFOID:0000000007576450
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, transmission range switch and provides shift con-
trol or lock-up control via CVT solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the OBD-related parts of the
CVT system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve mal-
function, etc.
It is much more difficult to diagnose an error that occurs intermit-
tently rather than continuously. Most intermittent errors are caused
by poor electric connections or improper wiring. In this case, careful
checking of suspected circuits may help prevent the replacement of
good parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT (or GST) or a circuit tester connected should be per-
formed. Follow the “DETAILED FLOW”.
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “Diagnostic Work Sheet” as shown on
the example (Refer to
) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.
DETAILED FLOW

ADDITIONAL SERVICE WHEN REPLACING TCM
ADDITIONAL SERVICE WHEN REPLACING TCM
Description
INFOID:0000000007576452
When replacing the TCM, perform the following work.
LOADING AND STORING OF CALIBRATION DATA
• The TCM acquires calibration data (individual characteristic value) of each solenoid that is stored in the
ROM assembly (in the control valve). This enables the TCM to perform accurate control. After the TCM is
replaced, check that the calibration data is correctly loaded and stored.
CAUTION:
When replacing TCM and transaxle assembly as a set, replace transaxle assembly first and then
replace TCM.
If the TCM is replaced in advance, perform “ADDITIONAL SERVICE WHEN REPLACING CONTROL
VALVE OR TRANSAXLE ASSEMBLY”. Refer to
.
Procedure
INFOID:0000000007576453
CAUTION:
Immediately after TCM is replaced or after control valve or transaxle assembly is replaced (after TCM
initialization is complete), self-diagnosis result of “P1701”, “P1709” may be displayed. In this case,
erase self-diagnosis result using CONSULT. After erasing self-diagnosis result, perform DTC “P1701”,
“P1709” reproduction procedure and check that malfunction is not detected. Refer to
1.
LOAD CALIBRATION DATA
1.
Shift the selector lever to the “P” position.
2.
Turn ignition switch ON.
3.
Check that “P” is displayed on shift position indicator on combination meter.
NOTE:
Displayed approximately 1 – 2 seconds after the selector lever is moved to the “P” position.
Does the shift position indicator display “P”?
YES
>> GO TO 3.
NO
>> GO TO 2.
2.
DETECT MALFUNCTIONING ITEM
Check the following items:
• Harness between the TCM and the ROM assembly inside the transaxle assembly is open or shorted.
• Disconnected, loose, bent, collapsed, or otherwise abnormal connector housing terminals
Is the inspection result normal?
YES
>> GO TO 1.
NO
>> Repair or replace the malfunctioning parts.
3.
STORE CALIBRATION DATA
1.
Turn ignition switch OFF and wait for 5 seconds.
2.
Turn ignition switch ON.
Does the shift position indicator display “P” at the same time when turning ON the ignition switch?
YES
>> WORK END
NO
>> Check harness between battery and TCM harness connector terminal. Refer to

ADDITIONAL SERVICE WHEN REPLACING CONTROL VALVE OR TRAN-
SAXLE ASSEMBLY
Description
INFOID:0000000007576454
When replacing the transaxle assembly/control valve, perform the following work.
ERASING, LOADING AND STORING OF CALIBRATION DATA
• The TCM acquires calibration data (individual characteristic value) of each solenoid that is stored in the
ROM assembly (in the control valve). This enables the TCM to perform accurate control. For this reason,
after the transaxle assembly/control valve is replaced, it is necessary to erase the calibration data previously
stored in TCM, to load new calibration data, and to store them.
ERASING OF CVT FLUID DEGRADATION LEVEL DATA
• TCM records the degradation level of the CVT fluid calculated from the vehicle driving status. Therefore, if
the transaxle assembly/control valve is replaced, it is necessary to erase the CVT fluid degradation level
data recorded by TCM.
Procedure
INFOID:0000000007576455
CAUTION:
Immediately after TCM is replaced or after control valve or transaxle assembly is replaced (after TCM
initialization is complete), self-diagnosis result of “P1701”, “P1709” may be displayed. In this case,
erase self-diagnosis result using CONSULT. After erasing self-diagnosis result, perform DTC “P1701”,
“P1709” reproduction procedure and check that malfunction is not detected. Refer to
1.
PREPARATION BEFORE WORK
With CONSULT
1.
Start the engine.
CAUTION:
Never drive the vehicle.
2.
Select “Data Monitor” in “TRANSMISSION”.
3.
Select “ATFTEMP COUNT”.
Is “ATFTEMP COUNT” 47 [equivalent to 20
°
C (68
°
F)] or more?
YES
>> GO TO 2.
NO
>> 1.
Warm up the transaxle assembly until “ATFTEMP COUNT” reaches “47” [equivalent to 20
°
C
(68
°
F)] or more.
2.
GO TO 2.
2.
PERFORM TCM INITIALIZATION
With CONSULT
1.
Turn ignition switch OFF.
2.
Turn ignition switch ON.
CAUTION:
Never start the engine.
3.
Select “Self Diagnostic Results” in “TRANSMISSION”.
4.
Shift selector lever to “R” position.
5.
Depress slightly the accelerator pedal (Pedal angle: 2.0/8) while depressing the brake pedal.
6.
Select “Erase” with step 5.
7.
Release brake pedal and accelerator pedal.
8.
Turn ignition switch OFF while keeping the selector lever in “R” position.
9.
Wait approximately 10 seconds.
10. Turn ignition switch ON while keeping the selector lever in “R” position.
11. Select “CALIB DATA” in “TRANSMISSION”.
12. Check that “CALIB DATA” value is as shown as in the following table.
