II - PARTICLE FILTER FORCED REGENERATION
PROCEDURE USING THE DIAGNOSTIC TOOL
a Connect the Diagnostic tool to the vehicle.
IMPORTANT
During forced regeneration of the particle filter,
the temperature of the exhaust pipe rises signifi-
cantly.
Always use one of the two kits approved for the
high temperatures reached during forced regen-
eration, whether the operation is carried out in
the workshop using an exhaust gas extractor, or
outside the workshop.
Ensure that when in use, the kit is not touching
the rear bumper when carrying out forced regen-
eration of the particle filter.
Note:
T o prevent engine racing, check the engine oil
level using the dipstick before running the forced
regeneration command.
The engine oil level must be between the
« MIN » and « MAX » marks on the dipstick.
