Onboard Diagnostics OBD2 MONITORS PM Filter Monitor - The particulate matter (PM) filter removes particulate matter from the exhaust stream by filtration. The filter has a honeycomb structure similar to a catalyst substrate, but with the channels blocked at alternate ends. This forces the exhaust gas to flow through the walls between the channels, filtering the particulate matter out. The filters are self-cleaning by periodic modification of the exhaust gas concentration in order to burn off the trapped particles (oxidizing the particles to form CO2 and water). The computer monitors the efficiency of the filter in trapping particulate matter, as well as the ability of the filter to regenerate (self-clean). The PM Filter Monitor is supported by “compression ignition” vehicles only. The PM Filter Monitor is a “Two-Trip” Monitor. If a fault is found on the first trip, the computer temporarily saves the fault in its memory as a Pending Code. The computer does not command the MIL on at this time. If the fault is sensed again on the second trip, the computer commands the MIL “On,” and saves the code in its long-term memory. OBD2 Reference Table The table below lists current OBD2 Monitors, and indicates the following for each Monitor: A. Monitor Type (how often does the Monitor run; Continuous or Once per trip) B. Number of trips needed, with a fault present, to set a pending DTC C. Number of consecutive trips needed, with a fault present, to command the MIL “On” and store a DTC D. Number of trips needed, with no faults present, to erase a Pending DTC E. Number and type of trips or drive cycles needed, with no faults present, to turn off the MIL F. Number of warm-up periods needed to erase the DTC from the computer’s memory after the MIL is turned off 26 OBD2
