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.
