- "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."
- },
- {
- "step": 4,
- "title": "Combustion Chamber Bore Cleaning & Teflon Seal Replacement",
- "instruction": "Clean injector combustion bores with dedicated brass cleaning brushes. If installing new injectors, verify protective plastic covers are intact; if resealing, use specialized pilot sizing cones to install new virgin PTFE Teflon seals."
- },
- {
- "step": 5,
- "title": "Injector Installation, Rail Alignment & Specified Torquing",
- "instruction": "Push injectors into fuel rail pockets and align into cylinder head bores. Torque fuel rail mounting bolts to 20 N\u00b7m (15 lb-ft) and injector hold-down clips to 10 N\u00b7m (89 in-lb). Reassemble intake manifold."

Codes de Defaut (DTC) & Protocoles de Diagnostic
Codes de defaut diagnostiques (DTC) courants déclenchés lorsque cet injecteur common rail subit une usure, des pannes de circuit ou une dérive d'étalonnage:
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.
