Dtc P0297: Vehicle Overspeed Condition; Dtc P0301: Cylinder No.1 Misfire Detected - Suzuki Grand Vitara 2011 Manual

DTC P0297: Vehicle Overspeed Condition

CAUTION
!
• The fault is present because the vehicle was running while diesel particulate filter after-sales
regeneration was in progress.
The vehicle speed should be zero during the regeneration.
Carry out an after sales regeneration referring to "Diesel Particulate Filter After-sales Regeneration
Procedure: For Diesel Engine Model in Section 1C".
DO NOT RUN THE VEHICLE.
If the fault is still present, substitute a known-good ECM and recheck.
• 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 becomes present during an diesel particulate filter after-sales regeneration with the
SUZUKI scan and a non negligible speed.
• If the fault is present, the diesel particulate filter after-sales regeneration in progress fails.

DTC P0301: Cylinder No.1 Misfire Detected

NOTE
• Cylinder number is counted from flywheel side.
• 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, engine performance is reduced and instability is possible.
• Priority when dealing with a number of faults:
Firstly, deal with fault "DTC P0201: Fuel Injector No.1 Circuit: For Diesel Engine Model" if it is
present or stored.
Troubleshooting
Check that the fuel injector No.1 calibration code using SUZUKI scan tool is correctly entered and that it
corresponds to the code inscribed on the corresponding injector.
Enter the code into an fuel injector that has not been programmed or where the code has been entered
incorrectly, if necessary.
Refer to "Registration Procedure for the Fuel Injector Calibration Code: For Diesel Engine Model in Section 1C".
Check the engine compression.
Repair if necessary.
Check the valve clearance and adjust if necessary.
In the event of several combustion misfire faults being present, check that the right fuel is being used.
Visually inspect the fuel injector 1 return pipes.
Repair if necessary.
If the fault is still present: apply Test 8 of Fault Finding-Tests referring to "Test 8: Injector malfunction: For Diesel
Engine Model".
If the fault is still present, substitute a known-good ECM and recheck.
