Fail-safe

INFOID:0000000006601680

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.

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-III (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 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-176

) 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.

COLLECT THE INFORMATION FROM THE CUSTOMER

Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred) using diagnosis worksheet. Refer to

TM-176, "Diagnostic Work Sheet"

>> GO TO 2.

CHECK SYMPTOM 1

Check the following items based on the information obtained from the customer.
• Fail-safe. Refer to

TM-169, "Fail-safe"

• CVT fluid inspection. Refer to

TM-184, "Inspection"

• Line pressure test. Refer to

TM-188, "Inspection and Judgment"
