Nissan Juke Service and Repair Manual : Service regeneration
Description
Service Regeneration is performed with CONSULT-III to reduce particulate matter in diesel particulate filter.
Service Regeneration should be performed in the following cases.
• ECM enters fail-safe mode because the amount of particulate matter in diesel particulate filter reaches the specified level.
NOTE
:
When ECM enters fail-safe mode because the amount of particulate matter in
diesel particulate filter
reaches the specified level, check whether or not DTC is stored in ECM. In the
case of DTC stored, perform
the Diagnostic Procedure for the DTC.
• ECM is replaced.
NOTE
:
Based on the signal from sensors ECM measures the amount of particulate matter
in diesel particulate filter
and stores the value in EEPROM (Electrically Erasable Programmable Read Only
Memory). When ECM is
replaced as new one, there is a difference between the actual amount of
particulate matter and the value
stored in new ECM, because the value stored in new ECM is initialized one. In
the case above, ECM cannot
perform regeneration control correctly. So, perform service regeneration to make
the amount of particulate
matter in diesel particulate filter zero.
• Component Inspection for diesel particulate filter is performed.
CAUTION:
To prevent engine racing, check engine oil level before running the forced
service regeneration command.
Work Procedure
1.START
1. Check engine oil level.
2. Start engine and warm it up to normal operating temperature.
3. Turn ignition switch OFF.
4. Turn ignition switch ON.
5. Select ???SERVC REGENERATION??? in ???WORK SUPPORT??? mode with CONSULT-III.
6. Touch ???START??? and wait for approximately 30 minutes.
NOTE
:
• Do not perform any vehicle operation during service regeneration.
7. Wait until ???END??? is displayed.
NOTE
:
• It takes approximately 30 minutes until ???END??? is displayed.
8. Turn ignition switch OFF and wait at least 10 seconds.
9. Check engine oil level.

RISKS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to
contamination. The risks associated with contamination
are:
• damage to or destruction of the high pressure injection system,
• components jamming,
• components losing seal integr ...
