Diesel Fuel Injection
Safety Precautions
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
• Route all lines and wires in their original locations.
• For example, fuel, hydraulic, Evaporative Emission (EVAP), coolant, refrigerant, brake fluid and vacuum lines.
• Ensure sufficient clearance to all moving or hot components.
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
• The fuel or fuel lines in the fuel system can become very hot (danger of scalding)!
• Wear protective eyewear, gloves and clothing during all work on the fuel system to prevent eye injuries and scalding.
• In addition, the fuel system is under pressure! Before opening the system, place a cloth around the connection area and release pressure by carefully loosening the connection!
• If the fuel system components between the fuel tank and high pressure fuel pump were removed or replaced, the fuel system must be filled in order to bleed it. Refer to => [ Fuel System, Filling and Bleeding ] Fuel System, Filling and Bleeding. (Avoid running the high pressure fuel pump dry.)
If special testing equipment is required during road test, note the following:
• Test and measuring instruments must be secured to the rear seat and operated by a second person from this location.
If the vehicle is involved in a collision while testing and measuring equipment is operated from the front passenger seat, the person sitting in that seat could be seriously injured when the airbag deploys.
To reduce the risk of personal injury and/or damage to the fuel injection and glow plug system, always observe the following:
• Only disconnect and connect the wires for the glow plugs and fuel injection system (including test leads) when the ignition is turned off.
• Only disconnect and connect the battery when the ignition is turned off or the Engine Control Module (ECM) could be damaged.
- Observe the notes after connecting the battery.
