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

TM-217

) 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.

ADDITIONAL SERVICE WHEN REPLACING TCM

Description

INFOID:0000000012200909

When replacing the TCM, perform the following work. For work procedure, refer to

TM-219, "Work Procedure"

TCM PROGRAMMING

• Since vehicle specifications are not yet written in a new TCM, it is necessary to write them with CONSULT.

CAUTION:

When replacing TCM, save TCM data on CONSULT before removing TCM.

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 simultaneously, replace transaxle assembly first and

then replace TCM.

Work Procedure

INFOID:0000000012200910

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

TM-281, "DTC

Logic"

(P1701),

TM-285, "DTC Logic"

(P1709).

CHECK NEW TCM PART NUMBER

Check new TCM part number to see whether it is blank TCM or not.

NOTE:

• Part number of blank TCM is 310F6-XXXXX.

• Check the part number when ordering TCM or with the one included in the label on the container box.
Is new TCM a blank TCM?

YES

>> GO TO 2.

>> GO TO 3.

SAVE TCM DATA (VEHICLE SPECIFICATIONS)

NOTE:

Save necessary data stored in TCM in CONSULT according to the following instructions:

With CONSULT

1. Turn ignition switch OFF.

2. Connect all of disconnected connectors.

3. Turn ignition switch ON.

4. Select “Re/programming, Configuration”.

5. Select “AT/CVT”.

NOTE:

If “AT/CVT” is not displayed and TCM data cannot be saved on CONSULT, GO TO 3.

6. Select “Programming”.

7. Save TCM data on CONSULT according to the CONSULT display.

>> GO TO 3.

REPLACE THE TCM

1. Turn ignition switch OFF and wait for 10 seconds.

2. Replace the TCM. Refer to

TM-328, "Removal and Installation"

>> GO TO 4.

ADDITIONAL SERVICE WHEN REPLACING CONTROL VALVE OR TRAN-
SAXLE ASSEMBLY

Description

INFOID:0000000012200911

When replacing the transaxle assembly/control valve, perform the following work. For work procedure, refer to

TM-219, "Work Procedure"

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.

Work Procedure

INFOID:0000000012200912

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

TM-281, "DTC

Logic"

(P1701),

TM-285, "DTC Logic"

(P1709).

CVT FLUID COOLER SYSTEM

TM-223

< BASIC INSPECTION >

[CVT: RE0F10B]

CVT FLUID COOLER SYSTEM

Cleaning

INFOID:0000000012200913

Whenever an automatic transaxle is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the

radiator must be inspected and cleaned.

Metal debris and friction material, if present, can be trapped or be deposited in the CVT fluid cooler. This

debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid.

In either case, malfunction of the newly serviced CVT may occur.

Debris, if present, may deposit as CVT fluid enters the cooler inlet. It will be necessary to back flush the cooler

through the cooler outlet in order to flush out any built up debris.

CVT FLUID COOLER CLEANING PROCEDURE

1. Position an oil pan under the transaxle's inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.
3. Disconnect the fluid cooler inlet and outlet rubber hoses from the

steel cooler tubes or bypass valve.

NOTE:

Replace the cooler hoses if rubber material from the hose

remains on the tube fitting.

4. Allow any CVT fluid that remains in the cooler hoses to drain into

the oil pan.

5. Insert the extension adapter hose of a can of Transmission

Cooler Cleaner into the cooler outlet hose.

CAUTION:

• Wear safety glasses and rubber gloves when spraying the

Transmission Cooler Cleaner.

• Spray Transmission Cooler Cleaner only with adequate

ventilation.

• Avoid contact with eyes and skin.

• Never breath vapors or spray mist.

6. Hold the hose and can as high as possible and spray Transmis-

sion Cooler Cleaner in a continuous stream into the cooler outlet

hose until CVT fluid flows out of the cooler inlet hose for 5 sec-

onds.

7. Insert the tip of an air gun into the end of the cooler outlet hose.
8. Wrap a shop rag around the air gun tip and end of the cooler

outlet hose.

9. Blow compressed air regulated to 5 to 9 kg/cm

(70 to 130 psi)

through the cooler outlet hose for 10 seconds to force out any

remaining CVT fluid.

10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connect the CVT

fluid cooler steel lines to the transaxle.

12. Remove the banjo bolts.
13. Flush each steel line from the cooler side back toward the tran-

saxle by spraying Transmission Cooler Cleaner in a continuous stream for 5 seconds.

14. Blow compressed air regulated to 5 to 9 kg/cm

(70 to 130 psi) through each steel line from the cooler

side back toward the transaxle for 10 seconds to force out any remaining CVT fluid.

15. Ensure all debris is removed from the steel cooler lines.
16. Ensure all debris is removed from the banjo bolts and fittings.
