the technician to test for DTCs in a certain manner.
Always follow published service procedures.

Fail This Ignition
This selection will display all DTCs that have failed during
the present ignition cycle.

History
This selection will display only DTCs that are stored in the
ECM’s history memory.  It will not display Type B DTCs
that have not requested the MIL (“Check Engine” lamp).  It
will display all type A and B DTCs that have requested the
MIL and have failed within the last 40 warm-up cycles.  In
addition, it will display all type C and type D DTCs that
have failed within the last 40 warm-up cycles.

MIL SVC or Message Requested
This selection will display only DTCs that are requesting
the MIL. Type C and type D DTCs cannot be displayed
using this option.  This selection will report type B DTCs
only after the MIL has been requested.

Test Failed Since Code Cleared
This selection will display all active and history DTCs that
have reported a test failure since the last time DTCs were
cleared.

Injector Test

This test is conducted to make it sure that appropriate
electric signals are being sent to injectors Nos. 1 – 4.
Tech–2 must be used for this test.

Test Procedure:

1. Connect Tech–2 to the vehicle DLC.
2. Set Ignition Switch to the “ON” position.
3. Select Control Test.
4. Select Injector Test.
5. Send instructions to each injector(Switch on), making

sure of injector working noise.

NOTE: If injector working noise (Clink) can hardly be
confirmed, remove the engine head cover noise
insulation.

Refer to Section 6A.

6. In the injector whose working noise has been

confirmed, its electric circuit can be regarded as
normal.
As for the injector whose working noise has not been
confirmed, its electric circuit or the injector proper is
faulty.

EGR Valve Test

This test is conducted to check EGR valve for its working.
This test needs Tech–2.

Test Procedure

1. Connect Tech–2 to vehicle DLC.
2. Switch on the engine.
3. Select “DIAGNOSIS” from the main menu.
4. Select Miscellaneous Test.
5. Select EGR Valve.
6. Instruct EGR Valve to check a data list.
7. If change in the data list shows a normal valve, the

working of EGR Valve can be judged to be normal.
