Dtc P2002: Diesel Particulate Filter Efficiency Below Threshold - Suzuki Grand Vitara 2011 Manual

1A-347 Engine General Information and Diagnosis: For Diesel Engine Model
Troubleshooting for CO0: Open circuit or short circuit to vehicle body ground
Check the condition of the additional heater relay No.2 and No.3.
Check the ECM connections.
Repair if necessary.
Check the additional heater relay No.2 and No.3. mounting connections.
If these checks are correct,
Check the continuity and insulation from vehicle body ground of the following connections:
• Between "C93-5" wire of additional heater relay No.2 mounting connector and "C85-19" terminal of ECM
connector
• Between "C94-3" wire of additional heater relay No.2 mounting connector and "E33-6" wire of main relay
connector
• Between "C95-5" wire of additional heater relay No.3 mounting connector and "C85-19" terminal of ECM
connector
• Between "C95-3" wire of additional heater relay No.3 mounting connector and "E33-6" wire of main relay
connector
Repair if necessary.
If the fault is still present, substitute a known-good ECM and recheck.
Troubleshooting for CC1: Short circuit to +12 V
Check the condition of the additional heater relay No.2 and No.3.
Check the ECM connections.
Repair if necessary.
Check the additional heater relay No.2 and No.3 mounting connections.
Check the continuity and insulation from +12 V of the following connection:
• Between "C93-5" wire of additional heater relay No.2 mounting connector and "C85-19" terminal of ECM
connector
• Between "C95-5" wire of additional heater relay No.3 mounting connector and "C85-19" terminal of ECM
connector
Repair if necessary.
If the fault is still present, substitute a known-good ECM and recheck.

DTC P2002: Diesel Particulate Filter Efficiency Below Threshold

CAUTION
!
The parameters must be reinitialised after any procedure is carried out on the diesel particulate filter.
Use command "Initialize Diesel PF data" on SUZUKI scan tool, and diesel particulate filter after-sales
regeneration referring to "Diesel Particulate Filter After-sales Regeneration Procedure: For Diesel
Engine Model in Section 1C" or "Diesel Particulate Filter Removal and Installation: For Diesel Engine
Model in Section 1K".
NOTE
• Conditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
• If the fault is present:
– Diesel particulate filter regenerations are inhibited.
– Blue and white fumes and black particles can be seen at the exhaust.
