Cautions
• Never perform service on any component of the system while the engine is running.
• Do not smoke while is servicing on the fuel system or any other system of the engine.
• Avoid contact with electric components that may produce sparks.
• Always check tanks, piping, hoses and other components of the fuel system for leakages.
• When the engine is in operation, do not touch on the injectors connectors. The high
tension can cause serious injuries.
• Do not bleed the fuel injection system with the engine in operation. The high pressure
in the system can cause serious injuries if disassembled.
• The ECM, under no circumstances, can be disassembled for any kind of service.
Only the Bosch authorized service station can check or repair any problem in this
component after analyzed by the scanner. The inappropriate repair causes the
cancellation of the component warranty and consequently the cancellation of the total
warranty of the engine.
• The solenoids installed on the Rail only can be disassembled if problems on its operation
are shown up by the scanner. Otherwise it must not be disassembled under any
circumstances.
• Before beggining to assembly the harness on the ECM, make sure that the battery cables
are disconnected.
• The repairing on the injection system only can be performed after 30 seconds of the
engine stop, necessary time to assure the total reduction of the pressure in the Rail.
