(4)

Measure the waveform.

｠

The waveform should show a normal pattern similar to the
illustration.

(5)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the waveform normal?

YES:

 It can be assumed that this malfunction is

intermittent. Refer to 00, How to Use Troubleshooting/
Inspection Service Points - How to Cope with Intermittent
Malfunctions P.00-15.

NO:

 Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 10.

STEP 10. Test the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic  Function  -  OBD-II  Drive  Cycle  -  Pattern  24  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0201 set?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.

CIRCUIT OPERATION

｠

The injector power is supplied from the injector relay
(terminal No. 3).

｠

The ECM controls the injector by turning the power
transistor in the ECM "ON" and "OFF".

TECHNICAL DESCRIPTION

｠

The  amount  of  fuel  injected  by  the  injector  is
controlled by the amount of continuity time the coil
is grounded by the ECM.

DESCRIPTIONS OF MONITOR METHODS
The ECM detects open circuit and short malfunction.
