HOW TO ERASE SELF-DIAGNOSTIC RESULTS (WITHOUT CONSULT-II)
1.
If the ignition switch stays “ON” after repair work, be sure to turn ignition switch “OFF” once. Wait for at
least 3 seconds and then turn it “ON” again.
2.
Perform “SELF-DIAGNOSTIC PROCEDURE (Without CONSULT-II)”. Refer to
.
3.
Turn ignition switch “OFF”. (The self-diagnostic results will be erased.)
10th judgement flicker is longer than others.
Line pressure solenoid valve circuit is short-circuited or discon-
nected.
Þ
Go to LINE PRESSURE SOLENOID VALVE.
Refer to
11th judgement flicker is longer than others.
The ECM-A/T communication line is open or shorted.
Þ
Go to CAN COMMUNICATION LINE.
Refer to
Lamp comes OFF.
PNP switch, overdrive control switch or throttle position switch cir-
cuit is disconnected or TCM is damaged.
Þ
Go to 21. TCM Self-diagnosis Does Not Activate (PNP &
Overdrive Control Switches, and Throttle Position Sensor).
Refer to
Flickers as shown below.
Battery power is low.
Battery has been disconnected for a long time.
Battery is connected conversely.
(When reconnecting TCM connectors.—This is a problem.)

Introduction
ECS0099W
The TCM receives a signal from the vehicle speed sensor, throttle
position sensor or PNP switch and provides shift control or lock-up
control via A/T solenoid valves.
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 a problem that occurs intermit-
tently rather than continuously. Most intermittent problems 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 problems. A road
test with CONSULT-II or a circuit tester connected should be per-
formed. Follow the “Work Flow”. Refer to
.
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a drive ability complaint. The cus-
tomer can supply good information about such problems, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “Diagnostic Worksheet” like the exam-
ple (
AT-258, "DIAGNOSTIC WORKSHEET"
) should be used.
Start your diagnosis by looking for “conventional” problems first. This
will help troubleshoot drive ability problems on an electronically con-
trolled engine vehicle.
Also check related Service bulletins for information.
