Diagnosis By “ABS” Warning Light
Illumination Pattern
In the event that there is abnormality in the “ABS” warning
light illumination pattern while the key is in the ON position
or if the warning light is actuated during driving, trouble
should be diagnosed on a illumination pattern basis as
follows:
No.

Diagnostic Trouble Codes (DTCs)
When the warning light in the meter remains ON, the
EHCU stores the fault identification and disables the
ABS.
1. How to display and erase DTCs:
NOTE:
If DTCs are not displayed, harness C-4 connector
terminal 30 and I-10 connector terminal 2 may be
disconnected. Repair the harness and try DTC
display again.
DTCs can be displayed also by TECH 2. Select mode
“F0: Diagnostic Trouble Codes” from Application
Menu.
1. How to start DTC display:
Confirm that the vehicle has come to a complete
stop (with the wheels standing still) and that the
brake pedal is not depressed. (Unless these two
conditions are satisfied, DTC display cannot be
started.)
With IGN OFF, connect #12 terminal with #4
terminal or # 5 terminal (GND) . Then turn IGN ON.

Tech 2 Features
1. Tech 2 is 12 volt system. Do not apply 24 volt.
2. After connect and/or install Tech 2 body, Vehicle
Communications Interface (VCI) module, PCMCIA
card and DLC connector, connect them to the vehicle
DLC.
3. After power off to the Tech 2, remove and reinstall the
PCMCIA card.
4. The PCMCIA card has a capacity of 10 Megabytes
which is 10 times greater than the memory of the Tech
1 Mass Storage Cartridge.5. The Tech 2 has the capability of two snapshots.
6. The PCMCIA card is sensitive to magnetism and
static electricity, so care should be taken in the
handling of the card.
7. The Tech 2 can plot a graph when replaying a
snapshot.
8. Always return to the Main Menu to press EXIT key
several times before shutting down.
9. To clear Diagnostic Trouble Codes (DTCs), open
Application Menu and press “F1: Clear DTC Info”.

8. Install injector harness assembly, reconnect
harness connecter to injector.
9. Record the identification marking of injector for
each cylinder that is indicated on the upper portion
of injector.

10. Install cylinder head assembly.
Refer to “Cylinder Head” in this manual.
11. Fill with about 300cc of engine oil from the high
pressure oil pipe installation port of the oil rail using
an oil filler.
If assembled without filling the oil rail with oil, the
time for engine starting will be longer.
12. Immediately install high pressure oil pipe and
tighten to specified torque.
Torque: 80 Nꞏm (8.1 kgꞏm / 57.9 lb ft)
13. Install cylinder head noise insulator cover.
Refer to “Cylinder Head” in this manual.
14. Install intercooler assembly.
Refer to “Intercooler” in this manual.
15. Install air cleaner cover and air duct.
16. Use TECH2 to rewrite injector data to ECM.
For rewriting method refer to section “Data
Programming in Case of ECM Change” of section
6E 4JX1 engine driveability and emissions in this
manual.NOTE:
1) On completion of servicing, bleed air from the
engine inside fuel passage by means of the priming
pump. (The priming pump should be operated more
times than in the case of conventional engines.)
2) As air is in the oil rail, it takes more time to start the
engine. Rough idling may occur while the air is
being bled completely after engine start, but it does
not indicate trouble.
The air will be bled and normal engine status will be
reached while the vehicle is driven for about 5 km
or engine is operated for about 5 minutes at 1500 to
2000 rpm.
3) The injector spare part will be provided for group
number B1, B2 and B3 only.
Injector Grade code Programming
(Injector Change)
In case of an injector change, the injector grade code
(category number) must be programmed by Tech-2.
Programming Procedure
1. Connect the Tech-2 to the vehicle DLC.
2. Turn the starter switch to the “ON” position.
3. Select the “Diagnosis” from the Main menu.
4. Select the “Programming” from the Application
menu.

Once the test vehicle has been identified an “Application
(Power train) Menu" screen appears. Please select the
appropriate application.
The following table shows, which functions are used for
the available equipment versions.
Diagnostic Trouble Codes
The purpose of the “Diagnostic Trouble Codes" mode is
to display stored TCM trouble codes.
When “Diagnostic Trouble Codes" is selected an
“Application Menu" screen appears.
Clear DTC Information
The purpose of the “Clear DTC Information" mode is to
command the clearing of stored TCM trouble codes.
When “Clear DTC Information" is selected, a “Clear
DTC Information", warning screen appears. This screen
informs you that by cleaning DTC's, “all stored DTC
information in controller will be erased".
Do you want to clear DTC's (Yes/No).
Press either the Yes or No key when answering.
After clearing codes, confirm system operation by test
driving the vehicle.
Allow the vehicle to shift through all four forward gears in
a manner which attempts to repeat the failure condition.
NOTE: When the trouble has not been repaired and thetrouble code cannot be erased, check the vehicle again.
DTC Information
When “DTC Information" is selected, an “Application
Menu" appears with a list of DTC information function
keys addressing DTC specifics and their origins.
Function key selections may vary for particular vehicle
and/or system.
Data Display
The purpose of the “Data Display" mode is to
continuously monitor data parameters.
The current actual values of all impor tant sensors and
signals in the system are display through F1 mode.
When “Data Display" is selected an “Application Menu"
appears.
See “TRANSMISSION DATA" and “TCC DATA” on next
page.
Snapshot
When “Snapshot" is selected an “Application Menu"
appears.
When “Transmission Snapshot" application is selected
from the “Application Menu", a “Snapshot Menu"
appears, displaying several options. “Snapshot" options
may vary from one system to another.
“Snapshot" allows a recording of all vehicle parameters.
There parameters may then be replayed at a future
point in time.
This action allows you to focus on making the condition
occur, rather than trying to view all of the data in
anticipation of the fault. The snapshot will collect
parameter information around a trigger point that you
select.
When a snapshot is taken. It is recorded onto the
PCMCIA memory card. When the Tech2 is powered
down. Snapshots are not lost.
Actuator Tests
The purpose of “Actuator Tests" mode is to check for
correct operation of electronic system actuators.
Lamps
You can operate the lamps by pressing the ON and OFF
buttons.
Preconditions: P or N position
Solenoid
Solenoid S1(1-2/3-4), S2(2-3) and TCC Solenoid
(Torque Converter Clutch)
You can operate the solenoids by pressing the ON and
OFF buttons.
Preconditions: P or N position, no vehicle speed, no
engine speed
Pressure Control Solenoid (PCS)
You can operate the PC Solenoid by pressing the ON
and OFF buttons. ON will command a maximum current
of 1000 mA and OFF a minimum of 200 mA.
