Inspection

[Coil Resistance Inspection]

Turn the ignition switch OFF.

Disconnect the injector connector (A).

Measure the resistance between the terminal 1 and the terminal 2.

Check if the value is within the specification.

Specification : 0.35 ~ 0.43 Ω [20℃(68℉)]

[Compression Test]

Turn the igntion switch OFF.

Connect the GDS to Data Link Connector (DLC).

Turn the ignition switch ON.

Select "Vehicle, Model year, Engine, System".

Select "Vehicle S/W Management".

10.

Select "Engine Test Function".

11.

Select "Compression Test".

12.

Perform the test as the message below.

caution

●

While cranking, the engine is not started.

caution

●

If a cylinder's engine speed is extremly higher or lower than the other cylinders, the cylinder's compression pressure is faulty.

[Idle Speed Comparison]

13.

Turn the ignition switch OFF.

14.

Connect the GDS to Data Link Connector (DLC).

15.

Turn the ignition switch ON.

16.

Select "Vehicle, Model year, Engine, System".

17.

Select "Vehicle S/W Management".

18.

Select "Engine Test Function".

19.

Select "Idle Speed Comparision".

20.

Perform the test as the message below.

caution

●

If the injection rate is too much or too less, the idle speed is extremely high or low.

[Injection Quantity Comparison]

21.

Turn the ignition switch OFF.

22.

Connect the GDS to Data Link Connector (DLC).

23.

Turn the ignition switch ON.

24.

Select "Vehicle, Model year, Engine, System".

25.

Select "Vehicle S/W Management".

26.

Select "Engine Test Function".

27.

Select "Injection Quantity Comparison".

28.

Perform the test as the message below.

caution

●

After replacing the faulty injector, check the veicle by performing the tests below.

[Waveform Inspection]

Turn the ignition switch ON.

Connect the GDS to Data Link Connector (DLC).

Turn the ignition switch ON.

Monitor the waveform of each injector.

Analyze the waveform.

Specification : Refer to "Waveform"
