Information:
ACTION REQUIRED
New DEF system Software is available that reduces the risk of an internal DEF injector leak by improved temperature management. Please update the DEF system software at the next opportunity.
Ensure that all adjustments and repairs that are carried out to the Diesel Emission Fluid (DEF) system are performed by authorized personnel that have the correct training. Before beginning ANY work on the DEF system, refer to Operation and Maintenance Manual, "General Hazard" for safety information.
Before Failure:
Check that the engine software is the latest version before updating the DEF pump software.
If the engine software is not the latest version, update the Engine Software first.
If needed, update the engine software with the latest available in SIS Web.
Flash the DEF Pump ECM with the software listed in the Parts Needed or latest available in SIS Web.
For flash programming of the ECM software, refer to Troubleshooting "ECM Software - Install".
After Failure:
Ensure the appropriate steps have been followed when diagnosing a DEF injector failure. Refer to UENR0662.
If it is determined that replacement of DEF injector is required, refer to Disassembly and Assembly Manual - Diesel Exhaust Fluid Injector - Remove and Install.
After the DEF injector has been replaced, perform the DEF system software update as detailed in the "Before Failure" section above.
