Suzuki Grand Vitara JB419. Manual - part 36
Engine Electrical Devices: 1C-5
6) Proceed after-sales regeneration automatically as
follows.
NOTE
Ensure to perform each step of regeneration
by observing carefully the engine speed and
the engine sound at each step. Because this
procedure does not finish automatically and
SUZUKI scan tool does not indicate any
status of this procedure and the result of
regeneration.
a) Phase 1: Warming up
The engine speed is raised to 1500 rpm for at
least 3 minutes or until engine coolant
temperature reaches 80
°C (176 °F)
b) Phase 2: Regenerating
Injection timing is shifted to post injection (a
change in the engine operation sound can be
heard) and start regeneration.
NOTE
Phase 2 lasts approximately 20 minutes.
c) Phase 3: Cooling down
The injection is shifted to normal timing again.
CAUTION
!
To avoid thermal shock in the diesel
particulate filter, do not stop engine at phase
3.
7) Confirm “Diesel PF inlet Temp” under “Data list” of
SUZUKI scan tool, and wait until it decreases to 200
°C (392 °F) or less.
8) Stop engine.
9) Turn ignition switch to OFF position, and wait for 15
minutes or more.
10) Clear DTC referring to “DTC Clearance in Section
1A”.
11) After engine is cooled, replace engine oil and oil filter
referring to “Engine Oil and Filter Change in Section
0B”.
12) Check as follows that aftersales-regeneration is
correctly performed.
CAUTION
!
When driving, be sure to select in safe place
where there is neither any traffic nor any
traffic accident possibility and be very
careful during driving to avoid occurrence of
an accident.
a) Drive vehicle in the following each condition in
order to make ECU recognize actually soot mass
after after-sales regeneration.
i)
At 80 km/h for 10 minutes
ii) At 40 km/h for 5 minutes
b) Using SUZUKI scan tool, check that “Diesel PF
soot mass” parameter is 8 g (0.28 oz) or less.
If it is over 8g (0.28 oz), aftersales regeneration
is not correctly performed.Proceed to next step.
13) If aftersales regeneration is not correctly performed,
check as follows.
CAUTION
!
Be sure to change engine oil after each after-
sales regeneration.
Otherwise, engine will be damaged due to
degraded engine oil.
a) Check that connection and/or hose of differential
pressure sensor.
If faulty condition is found, repair or replace it.
b) Restart aftersales-regeneration referring to
“Diesel Particulate Filter After-sales
Regeneration Procedure” and check the
following condition during this after-sales
regeneration.
• Check exhaust system for leakage.
If leakage is found, repair or replace faulty
condition.
• Using SUZUKI scan tool, check that the
following parameters are over 550
°C (1022
°F).
If not, replace catalytic converter referring to
“Exhaust System Components in Section 1K”.
– Diesel PF in Temp
– Diesel PF out Temp
c) After after-sales regeneration, check “Diesel PF
soot mass” in the same manner as step 12).
If “Diesel PF soot mass” is over 8 g (0.28 oz)
again, replace diesel particulate filter referring to
“Diesel Particulate Filter Removal and
Installation in Section 1K”.
