QUICK REFERENCE INDEX

Diagnosis by CONSULT-II
NOTICE
1.The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each
solenoid).
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
Manual 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. Gear position dis-
played on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve ªAº or ªBº 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.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION
AT-1034

Introduction
The TCM receives a signal from the vehicle-speed sensor, accel-
erator position sensor or PNP switch and provides shift control
or lock-up control via 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
operating condition and be free of valve seizure, solenoid valve
malfunction, etc.
It is much more difficult to diagnose a problem that occurs inter-
mittently 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
replacement 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 performed. Follow the ªWork Flowº. Refer to AT-1040.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with a driveability complaint. The
customer can supply good information about such problems,
especially intermittent ones. Find out what symptoms are present
and under what conditions they occur. A ªDiagnostic Worksheetº
like the example (AT-1038) should be used.
Start your diagnosis by looking for ªconventionalº problems first.
This will help troubleshoot driveability problems on an electroni-
cally controlled engine vehicle.

HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a problem. It is important to fully understand the symptoms
or conditions for a customer complaint.
Make good use of the two sheets provided, ªINFORMATION FROM CUSTOMERº and ªDIAGNOSTIC
WORKSHEETº, to perform the best troubleshooting possible.
CHECK IN
LISTEN TO CUSTOMER COMPLAINTS AND FILL OUT
ªINFORMATION FROM CUSTOMERº, AT-1037.
Check for any Service Bulletins.bRefer to FAIL-SAFE Service Notice or Precautions, AT-1006.
CHECK A/T FLUID LEVEL AND CONDITION. IF NG, PLACE
CHECK ON THE DIAGNOSTIC WORKSHEET, AT-1038.bRefer to A/T Fluid Check, AT-1041.
PERFORM STALL TEST AND LINE PRESSURE TEST.bRefer to Stall Test and Line Pressure Test, AT-1041, 1044.

d. Assemble cam ring, cam ring spring and spring seat. Install
spring by pushing it against pump housing.
e. While pushing on cam ring install pivot pin.
3. Install rotor, vanes and vane rings.
+Pay attention to direction of rotor.
4. Install oil pump housing and oil pump cover.
a. Wrap masking tape around splines of oil pump cover assem-
bly to protect seal. Position oil pump cover assembly in oil
pump housing assembly, then remove masking tape.
b. Tighten bolts in a criss-cross pattern.
5. Install new seal rings carefully after packing ring grooves with
petroleum jelly. Press rings down into jelly to a close fit.
+Seal rings come in two different diameters. Check fit
carefully in each groove.
Small dia. seal ring:
No mark
Large dia. seal ring:
Yellow mark in area shown by arrow
+Do not spread gap of seal ring excessively while install-
ing. It may deform ring.

Self-diagnosis
FUNCTION
+When a problem occurs in the ABS, the warning lamp on the
instrument panel comes on. To start the self-diagnostic
results mode, ground the self-diagnostic (check) terminal
located on ªData Link Connectorº. The location of the mal-
function is indicated by the warning lamp flashing.
+While DIFF-LOCK is on, anti-lock warning light flashes.
SELF-DIAGNOSIS PROCEDURE
Turn off DIFF-LOCK switch.
Drive vehicle over 30 km/h (19 MPH) for
at least one minute.
Turn ignition switch ªOFFº.
Ground terminal ª9º of ªData link connec-
torº with a suitable harness.
Turn ignition switch ªONº while ground-
ing terminal ª9º.
Do not depress brake pedal.
After 3.0 seconds, the warning lamp
starts flashing to indicate the malfunction
code No. (See NOTE.)
Verify the location of the malfunction
with the malfunction code chart. Refer to
the original Service Manual. Then make
the necessary repairs following the diag-
nostic procedures.
After the malfunctions are repaired,
erase the malfunction codes stored in
the control unit. Refer to the original Ser-
vice Manual.
Rerun the self-diagnostic results mode to
verify that the malfunction codes have
been erased.
Disconnect the check terminal from the
ground. The self-diagnostic results mode
is now complete.NOTE: The indication terminates
after five minutes.
However, when the ignition
switch is turned from
ªOFFº to ªONº, the indica-
tion starts flashing again.

Fuel Injection Timing Control System
DESCRIPTION
The target fuel injection timing in accordance with the engine speed and the fuel injection amount are
recorded as a map in the ECM beforehand. The ECM and the injection pump control unit exchange signals
and perform feedback control for optimum injection timing in accordance with the map.

System description
This system improves acceleration when the air conditioner is used.
When the accelerator pedal is fully depressed, the air conditioner is turned off for a few seconds.
When engine coolant temperature becomes excessively high, the air conditioner is turned off. This contin-
ues until the engine coolant temperature returns to normal.

If the engine speed is above 2,700 rpm with no load (for example, in neutral and engine speed over 2,700
rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies based on engine speed.
Fuel cut will operate until the engine speed reaches 1,500 rpm, then fuel cut is cancelled.
NOTE:
This function is different from deceleration control listed under ªFuel Injection Control Systemº,
EC-1019.

Air Bleeding
Pump the priming pump to bleed air.
+When air is bled completely, the pumping of the priming
pump suddenly becomes heavy. Stop operation at that
time.
+If it is difficult to bleed air by the pumping of the prim-
ing pump (the pumping of the priming pump does not
become heavy), disconnect the fuel supply hose
between the fuel filter and the injection pump. Then, per-
form the operation described above, and make sure that
fuel comes out. (Use a pan, etc. so as not to spill fuel.
Do not let fuel get on engine and other parts.) After that,
connect the hose, and then bleed air again.
