Defect
On heavy-duty diesel trucks compliant with the 2016 emissions regulations, the Engine Management System (EMS) program settings are incorrect. As a result, the diagnostic monitoring functions for fuel system pressure control and intake boost pressure sensor faults may not execute. The warning light that would alert the driver to these faults may therefore fail to illuminate.
Corrective action
On all vehicles, reprogram the EMS with the corrected/updated software.
