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.

Check injector connector terminal voltage (failed injector analysis)

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnect all injectors.

(3)

IG KEY "ON".

(4)

Check the voltage of all injector connector terminal 1 and 2.

1)

Secification : Terminal 1 : 0.4V~0.5V

Terminal 2 : 2.0V~2.5V

(5)

Is the measured voltage within the specification?

YES

a.

Go to "Component Inspection".

NO

a.

Refer to "DTC" guide corresponding to each problem occurred injector.

Injector #1 related problem : Refer to P0201 for open in injector circuit. Refer to P0262 for short in injectoer circuit.

Injector #2 related problem : Refer to P0202 for open in injector circuit. Refer to P0265 for short in injectoer circuit.

Injector #3 related problem : Refer to P0203 for open in injector circuit. Refer to P0268 for short in injectoer circuit.

Injector #4 related problem : Refer to P0204 for open in injector circuit. Refer to P0271 for short in injectoer circuit.
