Diagnostic Help.
The injector can be activated with the ISAT scan tool.
- Select "ACTIVATE".
- Select "INJECTOR 3".
The command activates the injector at a frequency of 0.5 Hz for 30 seconds.
Check The Wiring.
Intermittent faults may occur as a result of temporary short circuits and breaks in the wiring. Jiggle the wiring at several points and in different directions to ascertain whether the wiring harness, including any connectors, is causing the trouble. Observe the multimeter, ISAT scan tool or test lamp while doing this.
Diagnostic Procedure.
1. Check the injector's power supply
- Unplug the injector's 2-pin connector.
- Turn the ignition switch to the ON position.
- Connect a test lamp to pin 1 and battery negative (B-).
The test lamp should light up.
Did the test lamp light up?
YES: Continue with point 2.
NO: Repair or replace the lead between the 2-pin connector and crimped connection J111.
Then continue with point 3.
2. Check the control module's output to the injector
- Connect a test lamp to battery positive (B+) and pin 2 of the female connector.
- Connect the ISAT Scan Tool.
- Turn the ignition switch to the ON position.
- Select "ACTIVATE".
- Select "INJECTOR 3".
The test lamp should flash at a frequency of 0.5 Hz for 30 seconds.
Test lamp flashing?
YES: Change the injector and continue with point 3.
NO: Check the lead and repair or replace it if necessary. Then continue with point 3.
3. Final check
- Clear the diagnostic trouble code.
- Implementation of driving cycle:
^ Drive the car at varying engine loads and rpm for 5 minutes.
- Evaluation of driving cycle:
^ Check whether the diagnostic trouble code has recurred.
Has the diagnostic trouble code recurred?
YES: Continue at "Before Replacing a Control Module". Component Tests and General Diagnostics
NO: The steps taken to rectify the fault were correct.
