This Special Instruction provides information for the installation of the Diesel Particulate Filter Monitoring System.System Description
The Diesel Particulate Filter (DPF) is placed on the engine in order to remove the soot and any particulate matter from the engine exhaust. A diagnostic module kit is also provided, and must be installed on the vehicle in order to properly monitor DPF health and functionality. Note: The diagnostic module kit is a required component of the DPF.The system monitors engine back pressure and exhaust temperature. The system also provides information to the driver and maintenance personnel on the performance of the DPF.The Diagnostic Module (DM) monitors and records levels of the exhaust back pressure and the exhaust temperature entering the Diesel Oxidation Catalyst module of the DPF. Data is recorded to permanent memory. The operator can download data. The operator can review data in order to determine functional history and maintenance history. Alarm levels can also be set to record incidents of excessive back pressure, excessive exhaust temperature, or other system failures. The system will allow the warning diagnostic lights to be illuminated in order to alert the operator of system problems.Important Safety Information
