Before starting any troubleshooting, download a Product Status Report (PSR) from the affected engine. Ensure that the PDF and the XML version of the PSR are downloaded, with the Histogram option selected in the Download List.Follow the appropriate troubleshooting steps for the displayed fault codes. Document the results of the troubleshooting tests in the relevant tables. Refer to Tables 2, 3, and 4.If Troubleshoot requests the Pump and Electronics Unit (PEU) to be replaced, conduct the following inspection before removal of the PEU.
Check the DEF for contamination, if the relevant troubleshooting procedure has not instructed you to do so. Refer to "System Operation Testing and Adjusting", Diesel Exhaust Fluid Quality - Test for the correct procedure.
Inspect the DEF tank cap, DEF header filter, DEF pump filter for any visible obstruction

Inspect and photograph both ends of the DEF fluid lines. If the ends of the lines are damaged or swollen, replace the DEF lines. Refer to "Disassembly and Assembly", Diesel Exhaust Fluid Lines - Remove and Install.At the end of the service take another PSR irrespective of outcome. Ensure that the PDF and the XML version of the PSR are downloaded, with the Histogram option selected in the Download List.If the troubleshooting steps have required a component to be changed, hold all replaced components for 30 days for a possible Parts Return Request (PRR). Make sure to include the closed work order paperwork.In every instance submit a SIMSi report, complete with TIB number M0079072, CPI number 359775 and submit through the CPI feedback tool within the SIMSi.
