DTC P0304: Cylinder No.4 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 P0204: Fuel Injector No.4 Circuit: For Diesel Engine Model" if it is
present or stored.
Troubleshooting
Check that the fuel injector No.4 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 4 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.

DTC P0335: CKP Sensor Circuit

NOTE
• Conditions for applying fault finding procedures to stored faults: The fault is declared present:
– When an attempt is made to start the engine.
– The engine must be running.
• Use service wire for all operations on the controller connectors.
• The CKP sensor is consistent with the CMP sensor.
• If the fault is present:
– It is impossible to start the engine or the engine stops.
– The Red stop warning light (gravity 2 warning light) is lit.
