- {
- "step": 1,
- "title": "Relieve Residual Rail Pressure",
- "instruction": "Disconnect low pressure electric pump fuse. Crank engine 5-10 seconds to dissipate remaining fuel pressure in the high-pressure rail."
- },
- {
- "step": 2,
- "title": "Clean Injector Bores & Remove Old Seals",
- "instruction": "Clean bore thoroughly down to cylinder head seat. Never use metal picks that could scratch internal precision sealing walls."
- },
- {
- "step": 3,
- "title": "Compress Teflon Seals using Calibration Cone",
- "instruction": "Fit brand new Teflon combustion seal using mounting sleeve. Compress ring in step-down calibration die until outer diameter fits cleanly."
- },
- {
- "step": 4,
- "title": "Position Fuel Rail & Torque Bolts",
- "instruction": "Guide fuel rail assembly squarely into cylinder head ports. Tighten rail bolts evenly in two steps up to final torque of 21 N\u00b7m."
- },
- {
- "step": 5,
- "title": "Attach High Pressure Line & Verify Leakage",
- "instruction": "Thread high pressure feed line flare nut finger tight, then tighten to 30 N\u00b7m. Start engine and verify zero fuel misting or weeping."

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.
