In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 2% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
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.
For flash programming of the ECM software, refer to Troubleshooting "ECM Software - Install".
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.
