Procedure:
Required conditions for running this procedure:
Switch OFF accessories (ex. Heated seats, rear defroster, climate control, lights, etc.).
No fault entries recorded in the Engine Control Module (ECM).
Driving profile requires approximately 60-90 minutes.

General procedure in order to achieve “Readiness” (diagnostic checks complete)
The engine should be running (leave ignition key “on) during the entire procedure so that the driving profile is not
extended unnecessarily.
Some of the bits described in the table may be set by driving the vehicle a certain way. In this case, the
corresponding test procedure steps can be skipped.

Technical Bulletin
Procedure for Diesel Particulate Filter (DPF) Regeneration
Only one DPF regeneration is necessary per driving cycle. This means, if points 1-7 need to be carried out, only
one DPF regeneration is required.

In order to carry out regeneration:
Start adaptation channel 13 (DPF service regeneration) with security access. The DPF light switches ON and
stays ON for the entire time during regeneration. If the light switches OFF, then the regeneration process is
completed.
During regeneration, the vehicle needs to be driven at constant speed (50-70 mph or 80-120 km/h), preferably
using cruise control over a stretch of highway or country road. Periods of vehicle acceleration or coasting should
be avoided.
Note:
Obey all local and state traffic laws.

Description of Table 2
The column “NO.” shows an optimal sequence for conducting the readiness vehicle profile split into individual
“readiness categories”. The “Number” stands for a particular “readiness category”, and the “Letter” stands for a
“subcategory” which needs to be set in order to test the “readiness category”.
The column “MVB 89 Ok = 0” describes the “readiness category”. This bit = 0 when this category has
achieved readiness. The “subcategories” belonging to this “readiness category” no longer need to be
carried out.
The column “MVB 86 Ok = 1” describes the readiness “subcategory”. This bit = 1 after the “category” has been
tested. The “subcategories” no longer need to be tested when the “readiness category” bit for the particular
“subcategory” has already been set.
The column “procedure” describes the required vehicle profile which is necessary to set the bits in the “readiness
category” or in the “subcategory.
