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 ground cable, before • working on the 1.5 CRAIL system. Always follow the cleanliness and safety • instructions and use the correct tightening torques. Once the engine stops wait for 3 min then start • working on the 1.5 CRAIL system. Do not work on the injection system with the engine running. After opening the injection circuit it is strictly • forbidden 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 introduce contaminants into the system. Do not clean 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 • installing 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 1.5 CRAIL 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 1.5 • CRAIL 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 • unnecessarily HP pipe lines should not be bent and force • should not be applied. Failed or broken 1.5 CRAIL 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 ‘MIL’ / ‘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 • below 6 volts. Replace the battery and then start the engine. Do not remove the rail unnecessarily. The rail • can perform maximum 10 assembly/ disassembly cycles of pipes without any damage. Do not use any failed/ broken water Sedimenter • /fuel filters, even if there’s no external sign of damage. Keep hands or face (particularly eyes) out of • any high pressure leak. Do not remove the HP sensor from the rail. • Do not try to measure the resistance of the HP • sensor. This test is destructive for the internal components. Diesel Engine Ph-2 (CAFÉ) 97
