INTRODUCTION

The TCM receives a signal from the vehicle speed sensor, accelera-
tor pedal position sensor (throttle position sensor) or PNP switch.
Then provides shift control or lock-up control via A/T solenoid valves.
The TCM also communicates with the ECM by means of a signal
transmitted from sensing elements used with the OBD-related parts
of the A/T system for malfunction-diagnostic purposes. The TCM is
capable of diagnosing malfunctioning parts while the ECM can store
malfunctions in its memory.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good oper-
ating condition and be free of valve seizure, solenoid valve malfunc-
tion, 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 may not find the cause of the errors. A road test with
CONSULT-III (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 the
customer who has the driveability complaint. The customer can sup-
ply 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 in the example (Refer to

TM-77

) 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.

DETAILED FLOW

1.

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-77, "Diagnostic Work Sheet"

.

>> GO TO 2.

2.

CHECK SYMPTOM 1

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

TM-184, "Fail-Safe"

.

• A/T fluid inspection. Refer to 

TM-214, "Inspection"

.

• Stall test. Refer to 

TM-219, "Inspection and Judgment"

.

• Line pressure test. Refer to 

TM-220, "Inspection and Judgment"

.
