Work Flow INFOID:0000000003305975

INTRODUCTION
The TCM receives a signal from the vehicle speed sensor and PNP switch. Then it provides shift control or C
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- TM
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 E
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- H
ment of good parts.
A visual check only may not find the cause of the malfunctions. A
road test with CONSULT-III (or GST) or a circuit tester connected I
should be performed. Follow the "DETAILED FLOW".

Before undertaking actual checks, take a few minutes to talk with a K
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 L
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- M
cally controlled engine vehicle.
Also check related Service Bulletins.

1.COLLECT THE INFORMATION FROM THE CUSTOMER O
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred) using the diagnosis work sheet. Refer to TM-6, "Diagnostic Work Sheet".
