- "step": 1,
- "title": "High-Pressure Direct Injection Line Depressurization",
- "instruction": "Remove low-pressure fuel pump fuse in passenger cabin. Crank engine until it stalls to purge residual rail pressure. Disconnect negative battery ground cable before starting disassembly."
- },
- {
- "step": 2,
- "title": "Intake Manifold & Wiring Harness Clearance",
- "instruction": "Unbolt upper intake plenum, throttle body ducting, and PCV hose assembly. Unclip the main fuel injector wiring harness connectors from all four GDI injectors."
- },
- {
- "step": 3,
- "title": "High-Pressure Fuel Rail & Retaining Clip Removal",
- "instruction": "Unscrew the high-pressure fuel supply pipe fitting. Remove the fuel rail mounting bolts and gently withdraw the aluminum fuel rail assembly together with the injectors from the cylinder head."

رموز الاعطال التشخيصية (DTC) وبروتوكولات الفحص
رموز اعطال التشخيص الشائعة (DTC) التي يتم تسجيلها عند تآكل حاقن الديزل أو حدوث خلل كهربائي:
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.
