INTRODUCTION

The TCM receives signals from the vehicle speed sensor and transmission range switch. Then it provides shift

control or lock-up control via CVT solenoid valves.

The TCM also communicates with the ECM by means of signals

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 a malfunction that occurs inter-

mittently rather than continuously. Most intermittent malfunctions are

caused by poor electric connections or improper wiring. In this case,

careful checking of suspected circuits may help prevent the replace-

ment of good parts.

A visual check only may not find the cause of the malfunctions. A

road test with CONSULT (or GST) or a circuit tester connected

should be performed. 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 malfunctions, espe-

cially 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-6

) should be used.

Start your diagnosis by looking for “conventional” malfunctions first.

This will help troubleshoot driveability malfunctions on an electroni-

cally controlled engine vehicle.

Also check related Service Bulletins.
