DIAGNOSIS AND REPAIR WORK FLOW
Work Flow INFOID:0000000003130455
B
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, accelera- C
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 TM
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. E
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.

F
It is much more difficult to diagnose an error that occurs intermit-
tently rather than continuously. Most intermittent errors are caused G
by poor electric connections or improper wiring. In this case, careful
checking of suspected circuits may help prevent the replacement of
good parts. H
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".

J
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. K
Find out what symptoms are present and under what conditions they
occur. A "Diagnostic work sheet" as shown in the example (Refer to
TM-6) should be used. L
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. M

1.COLLECT THE INFORMATION FROM THE CUSTOMER
Get the detailed information from the customer about the symptom (the condition and the environment when
O
the incident/malfunction occurred) using diagnosis worksheet. Refer to TM-6, "Diagnostic Work Sheet".
>> GO TO 2. P
2.CHECK SYMPTOM 1
Check the following items based on the information obtained from the customer.
