This diagnostic code indicates an open circuit (low current) in either the solenoid or the wiring for the electronic unit injector for No. 3 cylinder.
The Electronic Control Module (ECM) detects the following condition:
• A low current condition (open circuit) for each of five consecutive attempts to operate
• Battery voltage is higher than 9 volts for 2 seconds.
System Response:
The ECM will log the diagnostic code. If equipped,
the diagnostic lamp will flash.
Possible Performance Effect:
The engine will have low power and/or rough running.
Troubleshooting:
1. Perform the “Injector Cutout Test”: This test will help identify a faulty electronic unit injector by comparing its reading with the other electronic unit injectors. If the faulty injector shows a significantly lower reading, it may need to be replaced.
2. Check for electrical faults: An electrical fault in the wiring unique to the electronic unit injector can prevent it from operating. Inspect the wiring for any signs of damage or wear. If an open circuit is detected, the wiring should be repaired or replaced.
3. Check for common wiring issues: An open circuit in the common wiring within the ECM can prevent multiple electronic unit injectors from operating. Inspect the common wiring and look for any signs of damage or loose connections. Repair or replace the wiring if necessary.
4. Perform the “Injector Solenoid Circuit – Test”: This diagnostic procedure will help identify any issues with the injector solenoid circuit. Follow the instructions provided in the Perkins service manual or seek assistance from a qualified technician.
5. Monitor the ECM: The ECM will continue to attempt to operate the electronic unit injector even after the diagnostic code has been logged. However, if an open circuit is present, the injector will not function. Monitoring the ECM for any additional fault codes or performance issues can provide further insight into the problem.
In conclusion, troubleshooting and repairing the Perkins 1106D Generation CID 0003 FMI 05 trouble code requires careful inspection of the electronic unit injector and its associated wiring. By following the steps outlined above and referring to the Perkins service manual, you can effectively resolve this issue and restore the engine’s performance.
