DIAGNOSIS AND TESTING)
Diagnostic Test
1.OTHER DTC’S
With the scan tool, read DTCs.
Are all 6 of the injector DTC’s (P0201 - P0206) present?

Go To 2
No>>
Go To 3
2.PASS TROUGH CONNECTORS OPEN
Inspect wiring harness for signs of multiple open circuits between the ECMand the injector pass through connec-
tors. Inspect the wiring harness between the pass through connectors to theinjectors.
Are there open circuits in the wiring harness?
Ye s>>
Repair or replace the open connectors or wiring.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL). (Refer to 8 - ELECTRICAL/ELEC-
TRONIC CONTROL MODULES/ENGINE CONTROL MODULE - DIAGNOSIS AND TESTING)
No>>
Go To 3
3.FUEL INJECTOR
Turn the ignition off.
Disconnect the pigtail nuts from the suspect injector. Using an Ohmmeter,measure the resistance between the sole-
noid posts of the injector.
NOTE: Be sure to zero the ohm meter prior to checking the injector circuit.
Is the resistance less than 1 ohm and greater than 0 ohms?
Ye s>>
Go To 4
No>>
Replace the fuel injector.
