- {
- "step": 1,
- "title": "High-Pressure Fuel Pressure Relief & Battery Safety",
- "instruction": "Disconnect negative battery terminal. Remove fuel pump fuse and crank engine for 5 seconds to depressurize the 200-bar fuel rail. Allow turbocharger assembly to cool completely."
- },
- {
- "step": 2,
- "title": "Engine Cosmetic Cover & Intake Ducting Disassembly",
- "instruction": "Remove Skyactiv-G engine cover and unbolt upper intercooler pipe and bracket assemblies to expose the high-pressure fuel pump mounted on the cylinder head cover."
- },
- {
- "step": 3,
- "title": "Electrical Connector & Fuel Line Detachment",
- "instruction": "Disconnect the fuel pressure control valve connector. Using a 17mm flare nut wrench, loosen high-pressure steel delivery pipe union nuts (counter-holding pump fitting). Release low-pressure supply line clamp."
- },
- {
- "step": 4,
- "title": "Camshaft Base Circle Alignment & Pump Removal",
- "instruction": "Turn crankshaft pulley clockwise until the high-pressure pump camshaft drive lobe is at base circle to minimize spring load. Alternately loosen mounting bolts 1/2 turn at a time and remove pump."
- },
- {
- "step": 5,
- "title": "Roller Tappet Inspection & New Pump Installation",
- "instruction": "Inspect roller tappet inside head bore for scoring or surface fatigue. Lubricate new pump O-ring with fresh synthetic oil. Place pump square on head and torque bolts alternately to 14 N·m."
- },
- {
- "step": 6,
- "title": "High-Pressure Tube Torquing & Diagnostic Fuel Pressure Test",
- "instruction": "Thread high-pressure tube nuts by hand, then torque flare nuts to 28 N·m. Reinstall intercooler ducting. Cycle ignition key ON-OFF 3 times, inspect for fuel leaks, and verify actual fuel rail pressure via OBD2."

Ariza Kodlari (DTC) ve Teshis Protokolleri
Bu common rail enjektorunde asinma, devre arizasi veya kalibrasyon kaymasi olustugunda tetiklenen yaygin ariza kodlari (DTC):
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
Injector Circuit Malfunction / Open Circuit
Solenoid coil resistance drift (0.2-0.5 Ω) or piezo stack degradation triggers driver stage shutdown on affected cylinders.
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
