CONSULT-IIECS004NW
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” (AT - 2 7 3 , "Diagnostic Procedure
Without CONSULT-II"), place check marks for results on the “DIAGNOSTIC WORKSHEET”,AT-280, "DIAG-
NOSTIC WORKSHEET". Reference pages are provided following the items.
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.
SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)
1. Turn on CONSULT-II and touch “A/T” for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground cir-
cuit. Refer toAT - 3 4 7 , "
TCM Terminals and Reference Value".If
result is NG, refer toPG-2, "
POWER SUPPLY ROUTING".
2. Touch “SELF-DIAG RESULTS”.
Display shows malfunction experienced since the last erasing
operation.
CONSULT-II performs “REAL TIME DIAG”.
Also, any malfunction detected while in this mode will be dis-
played at real time.

TROUBLE DIAGNOSIS — INTRODUCTIONPFP:00000
IntroductionECS004TF
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 toAT-284, "
Work 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 problems, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “Diagnostic Worksheet” like the exam-
ple (AT-280, "
DIAGNOSTIC WORKSHEET") should be used.
Start your diagnosis by looking for “conventional” problems first. This
will help troubleshoot driveability problems on an electronically con-
trolled engine vehicle.
Also check related Service bulletins for information.

lWhen measuring line pressure at stall speed, follow the
stall test procedure.
Line pressure: Refer toAT-563, "
SERVICE DATA AND SPECIFI-
CATIONS (SDS)".
JUDGEMENT OF LINE PRESSURE TEST
Road TestECS004VU
DESCRIPTION
lThe purpose of the test is to determine overall performance of A/
T and analyze causes of problems.
lThe road test consists of the following three parts:
1. Check before engine is started
2. Check at idle
SAT493G
Judgement Suspected parts
At idleLine pressure is low in all positions.
lOil pump wear
lControl piston damage
lPressure regulator valve or plug sticking
lSpring for pressure regulator valve damaged
lFluid pressure leakage between oil strainer and pressure regulator valve
lClogged strainer
Line pressure is low in particular posi-
tion.
lFluid pressure leakage between manual valve and particular clutch
lFor example, line pressure is:
-Low in “R” and “1” positions, but
-Normal in “D” and “2” positions.
Therefore, fluid leakage exists at or around low and reverse brake circuit.
Refer to “CLUTCH AND BAND CHART”,AT-19, "
CLUTCH AND BAND
CHART".
Line pressure is high.
lMaladjustment of throttle position sensor
lA/T fluid temperature sensor damaged
lLine pressure solenoid valve sticking
lShort circuit of line pressure solenoid valve circuit
lPressure modifier valve sticking
lPressure regulator valve or plug sticking
lOpen in dropping resistor circuit
At stall
speedLine pressure is low.
