UNTIL MESSAGE IS CLEARED”
– “CLEANING EXHAUST FILTER CONTINUE
DRIVING”
– “DIESEL PARTIC FILTER IS FULL CONTINUE

The DPF will clean itself as part of normal operation.
Several factors including fuel consumed, hours of
engine operation and miles driven are monitored by the
engine control module (ECM). The self-cleaning occurs
approximately once per tank of fuel. Under certain
driving conditions, such as extended idling,
stop-and-go traffic, etc., the DPF cannot clean itself.

Notice: Instruct the customer that in order for the
filter to clean itself, the vehicle must be driven
above 30 mph (50 km/h) until the message clears.
⇒ If the customer continues to drive with the DPF
warning message displayed and the exhaust filter
is not cleaned as required, the malfunction indicator
lamp will illuminate and the ENGINE POWER IS

will be necessary.

Messages Displayed in the Driver Information
Center (DIC) When DPF Cleaning is Required
If any of the messages appear on the driver information
center (DIC) then a DPF cleaning (regeneration) is
required. This messages are 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 messages are 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.
Notice: ADVISE THE CUSTOMER ABOUT ALL OF
THE FOLLOWING INFORMATION:

make the message disappear temporarily and not

Diesel Engine Supplement and review the
information titled: “Diesel Particulate Filter”, in
order to familiarize them with the operation of the
system.

5. Extended idle time MUST be avoided while the
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
30 mph (50 km/h) UNTIL the warning message
goes OFF.
7. Ignoring the message and continuing to drive with
the warning message ON and the exhaust filter not
being cleaned as required will eventually result in
the following:
7.1. The malfunction indicator lamp (MIL) will
illuminate at which point the DPF warning
message will be displayed and a chime will
also sound.
7.2. Diagnostic Trouble Code DTC P2463 will be
set as a result of excessive soot loading in
the DPF.
7.3. The Engine Power Is Reduced message will
be displayed. The engine WILL operate in
reduced engine power when this occurs.
7.4. Once this occurs, self cleaning of the DPF is
no longer possible and dealer service will be
necessary.
7.5. Possible irreversible damage to the DPF may
occur, requiring repair or replacement.
7.6. Advise the customer that if following the
diagnostic procedure for DTC P2463 in SI
results in a DPF system malfunction NOT
BEING found, the Diesel Particulate Filter
(DPF) Service Regeneration SHOULD NOT
BE CHARGED TO GM WARRANTY.

vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
