GENERAL 3 1.3 PRECAUTIONS OF COMMON RAIL SYSTEM (CR SYSTEM) Follow the below recommended cleanliness procedures before removal of any system components: This is to prevent dust entry in the system and to avoid damage to the precisely machined common rail system components· • Wash hands before the work. If necessary wear new plastic gloves. • As soon as there is an opening into the system, it must be blocked using special cap. After removal and plugging, each component of the injection system must be stored in a new hermetically sealed bag. • All plugs / caps and packaging are disposable and should be discarded after single use. • •Before disconnecting the battery make sure that no data is required from the electronic control unit (ECU), as battery cable disconnection will erase any fault codes and idle / drive values held in the keep alive memory (KAM). It is not necessary to disconnect or remove electronic control modules. • Disconnect the battery negative cable. • Follow the cleanliness and safety instructions and use the correct tightening torques. • Once the engine stops wait for 5 min., and then start working on the CR system. Do not work on the injection system with the engine running. • After opening the injection circuit it is strictly for-bidden to use any tools/ equipment made of a material which may cause a risk of shedding particles or fibers (wood, cloth, cardboard…). In the same way, the use of a blower, brush or bristles is banned because these tools are liable to intro-duce contaminants into the system. • Avoid cleaning of the injectors, even with an ultrasonic cleaner. • The packaging for the spare parts should be opened just before use. The special caps must not be removed until the final connection/installation. The plugs and bags must be discarded after use. • Any part dropped must not be used. Before in-stalling the injector, it is essential to ensure that the wells are clean. • Before connecting the harness, check the cleanliness of the connectors, particularly any fluids near electrical connections. • Before removing any CR components, vacuum external area with the help of vacuum cleaner to avoid possible contamination. Don’ts • HP pipes are one time use only avoid unnecessary removal and do not reuse. • Do not leave open inlets and outlets of CR components–Cap them immediately • Flushing of CR components should be avoided. • Do not remove battery, sensor & Actuator connections when key is ON • Do not spray water on the ECU • Sensor connections should not be removed un-necessarily • HP pipe lines should not be bent and force should not be applied. • Failed or broken CR components should not be used, leakage may cause injury • Don’t let ECU body touch any metallic part while the ECU is powered ON (Ignition key switched “ON”). • Never try to dismantle any engine part while the ECU is powered ON. • Don’t keep any sensor branch hanging /loose while assembly. Fix them properly using clips provided in W/H. • Don’t try to crank the engine without connecting any of the sensors. • Don’t remove any sensor /injector connector once fitted and locked properly. • Do not run the vehicle with Check Engine lamp ON. • Do not remove back-leak pipes unless the Injectors have to be removed. • Do not bleed the air by removing or loosening the HP pipes. • Do not start the vehicle if battery voltage is low. • The ECU gets tripped if the battery voltage is be-low 6 volts. Replace the battery and then start the engine. • Do not remove the rail unnecessarily. • Do not clean the Injectors with pressurized water. The injector is not designed to be washed with pressurized water. • Do not clean the HP pipes with compressed air, oil or water. Cleaning may dirt HP pipes and CR system. • Do not use any failed/ broken water Sedimenter /fuel filters, even if there’s no external sign of damage.
