1.

Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damge of component.

2.

Perform checking procedure as follows.

(1)

Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.

(2)

Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking device and connecting condition between terminal and wiring.

note

Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for checking connecting condition. ( after checking, reconnect the pin at correct position. )

3.

Is the problem found?

YES

a.

Repair the trouble causing part and go to "Verification of Vehicle Repair".

NO

a.

Go to "Power Circuit Inspection".

1.

IG KEY "OFF", ENGINE "OFF"

2.

Disconnect injector #3 connector and ECM connector.

3.

Check continuity between injector #3 connector terminal 2 and ECM connector(CDD-A) terminal 46.

1)

Specification : Continuity (below 1.0Ω )

4.

Is the measured resistance within the specification?

YES

a.

Go to "Control Circuit Inspection".

NO

a.

Repair open in injector #3 power circuit and go to "Verification of Vehicle Repair".

1.
