62-564 DIAGNOSIS-ENGINE CONTROL SYSTEM

(d). Measure the voltage between No.1cylinder
fuel injector pin 1 and the ground.
Standard voltage:

Connect the pin by Standard value
multimeter
Fuel injector
(1)-Grounding Battery voltage

Is the inspection result normal?

YES>To step 4。
No >Repair or replace the power wiring harness of fuel injector.

4. Check the control circuit of fuel injector

(a). Ignition switch: LOCK。
(b). Disconnect the No.1 cylinder fuel injector connector and ECU connector E01.

(c). Measure the resistance between No.1
cy linder f uel injec t or pin2andt he
ECUconnectorE01pin33 .
Standard resistance:

Connect the pin by Standard value
multimeter

Fue l i nj ector (2)- Approx 0Ω
E01(33)

Is the inspection result normal?
YES>To step 5。
No >Repair or replace fuel injector control circuit wiring harness

5. Replace and check the fuel injector

(a). Replace the fuel injector.
(b). Using the diagnostic tool performs theDTCconfirmation step and the steps of
reading the sensor data stream.
(c). Read the fuel injector data displayed on the diagnostic instrument.

Is the inspection result normal?
YES> Replace the fuel injector.
No >To step 6。
