- {
- "step": 1,
- "title": "Low-Pressure Supply Bleed & Battery Disconnect",
- "instruction": "Remove fuel pump fuse from underhood junction box. Crank engine for 5 seconds to depressurize fuel lines. Disconnect vehicle negative 12V battery terminal."
- },
- {
- "step": 2,
- "title": "Engine Beauty Cover & Noise Damper Removal",
- "instruction": "Unbolt engine cover and pull back the heavy rubber noise shield covering the high-pressure fuel pump on top of the valve cover."
- },
- {
- "step": 3,
- "title": "High-Pressure Pipe & Harness Disconnection",
- "instruction": "Unplug electrical solenoid harness. Use a 17mm line wrench with counter-torque to disconnect high-pressure metal fuel pipe from pump outlet."
- },
- {
- "step": 4,
- "title": "Pump Removal & Roller Lifter Tappet Check",
- "instruction": "Loosen mounting bolts alternately in half-turn increments. Lift pump out and remove the roller tappet. Inspect tappet face and camshaft lobe for wear grooves."
- },
- {
- "step": 5,
- "title": "New Pump Installation & Torque Sequence",
- "instruction": "Lubricate new Viton O-ring and roller tappet with fresh oil. Rotate engine to lowest cam profile. Torque mounting bolts to 13 N·m (115 in-lb) and fuel pipe union nut to 28 N·m (21 lb-ft)."

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.
