The Delphi Sealed Rail Kit (YDT278) is a unique piece of diagnostic equipment that identifies on-vehicle the individual components of a Common Rail system that are failing. This kit has successfully provided workshops throughout the world with a low-cost, all-makes diagnostic solution for mechanical faults on light-duty Common Rail vehicles.
The introduction of the False Actuator Kit (YDT410) in 2005 extended the YDT278's capability further, enabling the garage to diagnose actuator failures within Common Rail pumps.
The False Actuator Kit has been designed to work in conjunction with the Sealed Rail Kit to further interrogate the pump when a reduction in the pres sure being generated within the CR system has been identified.
When maximum pressure cannot be generated using the Sealed Rail kit and the vehicle actuator, the false actuator is fitted in order to enable the pump to generate full system pressure. If the pump generates the correct pressure with the false actuator in place then the vehicle actuator is deemed to be at fault and should be replaced. If the pressure is still below the required level when tested with the false actuator, then there is a mechanical failure within the pump.
Delphi will supply a series of all-makes test data for each actuator in order that the user can be fully confident in the diagnostic results.
The False Actuator Kit must only be used when the Sealed Rail is fitted to the vehicle. The use of false actuators without the Sealed Rail leads to extreme high pressures being generated by an uncontrolled system and poses a severe safety risk.
