The "CLEAN EXHAUST FILTER SEE OWNERS MANUAL NOW" message may be displayed on the driver information center (DIC) with a DTC
P2463 set.
This is a result of the customer NOT DRIVING the vehicle at the required speed and necessary amount of time for a self cleaning (regeneration) of the
diesel particulate filter (DPF) to occur when the message is displayed.
CLEAN EXHAUST FILTER SEE OWNERS MANUAL NOW
The "CLEAN EXHAUST FILTER SEE OWNERS MANUAL NOW", message will appear on the driver information center (DIC) when a DPF
regeneration is required. This message is displayed to NOTIFY the DRIVER that the status of the vehicle has changed and ACTION is required by the
DRIVER to correct the condition. The message is not a onetime display and will occur periodically through the lifetime of the vehicle when a DPF
regeneration is required based on engine run time, fuel consumed and distance traveled since the last DPF regeneration.
1. Perform the Diagnostic System Check - Vehicle.
2. Is DTC P2463 set?
‹› If DTC P2463 is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle in SI. After following the diagnostic procedure return to this
bulletin and PROCEED to Step 3.
‹› If DTC P2463 is not set, then proceed to Step 3 and inform the customer as indicated.
Important
ADVISE THE CUSTOMER ABOUT ALL OF THE FOLLOWING INFORMATION:
3. The importance of the message and responding to it immediately. Clearing the message will only make the message disappear temporarily and not
correct the problem.
4. Guide the customer to their Duramax(TM) Diesel Engine Owners Manual Supplement and review the information titled: "Diesel Particulate
Filter", in order to familiarize them with the operation of the system.
5. Extended idle time should be avoided while the "Clean Exhaust Filter" message is displayed because the DPF system is not capable of self
cleaning at idle.
6. Instruct the customer that the most efficient way to clean the filter is to DRIVE the vehicle at more than 50 km/h (30 mph) for approximately
20-30 minutes, UNTIL the warning message goes OFF.
7. Ignoring the message and continuing to drive with the DPF warning message ON and the exhaust filter not being cleaned as required will
eventually result in the following:
1. The malfunction indicator lamp (MIL) will illuminate at which point the DPF warning message will be displayed and a chime will also sound.
2. Diagnostic Trouble Code DTC P2463 will be set as a result of excessive soot loading in the DPF.
3. The Engine Power Is Reduced message will be displayed. The engine WILL operate in reduced engine power when this occurs.
