G92396t3 : CHECK THE INJECTOR COIL RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the relevant injector electrical connector (IJ1 to 6).
3. Measure the resistance between the injector pins.

- Is the resistance between 12 and 16 ohms?

-> Yes

-> No
INSTALL a new injector. CLEAR the DTC. TEST the system for normal operation.

G92396t4 : CHECK THE INJECTOR COIL INSULATION
1. Measure the resistance between the injector pin 1 and the injector body.
2. Measure the resistance between the injector pin 2 and the injector body.

- Are both resistances greater than 10 Mohms?

-> Yes

-> No
INSTALL a new injector. CLEAR the DTC. TEST the system for normal operation.

G92396t5 : CHECK THE INJECTOR SUPPLY VOLTAGE
1. Turn the ignition switch to the ON position.
2. Disconnect the relevant injector harness electrical connector (IJ1 to 6).
3. Measure the voltage between the relevant injector harness electrical connector (IJ1 to 6) pin 2 and GROUND.

- Is the voltage greater than 12 Volts?

-> Yes

-> No
REPAIR the circuit between the relevant injector harness electrical connector, (IJ1 to 6) pin 2 and battery. This circuit includes the power distribution fuse box, fuse 41, and the EMS control relay. CLEAR DTC. TEST the system for normal operation.

G92396t6 : CHECK THE INJECTOR GROUND CIRCUIT
1. Turn the ignition switch to the OFF position.
2. Disconnect the ECM electrical connector EN16.
3. Measure the resistance between the relevant injector harness electrical connector (IJ1 to 6) pin 1 and EN16 pins as follows -

- Is the resistance less than 5 ohms?

-> Yes

-> No
REPAIR the circuit between the relevant injector harness electrical connector pin 1 and the ECM electrical connector. CLEAR the DTC. TEST the system for normal operation.

G92396t32 : CHECK THE INJECTOR GROUND CIRCUIT FOR SHORT CIRCUIT TO BATTERY
1. Measure the voltage between the relevant injector harness electrical connector (IJ1 to 6) pin 1 and GROUND.

- Is the voltage greater than 1 volt?

-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> No

G92396t33 : CHECK THE INJECTOR GROUND CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. Measure the resistance between the relevant injector harness electrical connector (IJ1 to 6) pin 1 and GROUND.

- Is the resistance less than 10,000 ohms?

-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> No
INSTALL a new ECM. Before replacing a ECM, contact Dealer technical support.
