tool (Diagmaster), check the failure history, and
save the project.
• Before
removing
the DPF for cleaning, keep the
records of the engine serial number, filter comp
(DPF) part number, filter comp (DPF) serial
number, catalyst (DOC) part number, catalyst
(DOC) serial number, and engine operating time,
which are required in preparing the DPF
cleaning order form.
• Since the engine operating time is recorded in
the engine ECU, check the operating time by
connecting the service tool (Diagmaster).
• When installing and removing the muffler full
assembly (DPF), make sure that the temperature
sensor, differential pressure sensor, and
differential pressure pipe do not make contact
with surrounding parts.
