PROHIBITED OPERATIONS: SIEMENS HDI DIRECT INJECTION SYSTEM
Engine: DT17BTED4
Cleaning.
The use of high pressure cleaners is prohibited.
Do not use compressed air.
Fuel supply circuit.
Required fuel: Diesel.
WARNING: Do not use other fuels.
Electrical circuit.
Swapping injection ECUs between two vehicles will render it impossible to start either vehicle.
It is forbiddento supply a diesel injector with 12 volts.
Do not disconnect a diesel injector when the engine is running.
Fuel high pressure pump.
Do not separate the fuel high pressure pump (1)from the following components:
- The sealing ring (a)(no replacement parts).
- The high pressure outlet connector (b)(will cause a malfunction).
- The fuel pressure regulator (c)(no replacement parts).
- The flow electrovalve (d)(no replacement parts).
