ACTION REQUIRED

Show/hide table

Before completing this Rework Procedure, please review the safety actions in the Operation and Maintenance Manual for your machine.

Choose one of the following actions:

Before Failure: If electronic unit fuel injectors have not failed, reflash the engine ECM with the new software. The new software offers enhanced protection to the fuel system if the fuel/water separator is not drained of water when the "Water Separator Full Indicator" is displayed.

After Failure: If electronic unit fuel injectors have failed, replace the injectors and reflash the engine ECM with the new software.

For detailed instructions on removing and installing the injectors, refer to UENR0633, Disassembly and Assembly, "Electronic Unit Injector - Remove" and "Electronic Unit Injector - Install".
