Product Description

RA****0 Rail Pressure Diagnoser
RA****0 Rail Pressure Diagnoser is the updated design to test rail pressure sensors by Bosch, Denso and Delphi for common rail diesel engines. RA****0 can be used to diagnose common rail diesel engine faults with no interference to engine ECU during engine running by the site of a fault vehicle.There will be no longer any need to use a troublesome mechanical gauge to monitor rail pressure.
This instrument is a powerful indispensable tool for repair technicians to diagnose ECU, fuel system and rail pressure sensor for a common rail engine with problems,such as difficult to start or lack of power.
Design Features：

 Compact and easy to use
  Test Bosch rail pressure sensors made by
      Bosch, in 4 scales, *****0bar, *****0bar, *****0bar and *****0bar
      Denso, *****0bar
      Delphi, *****0bar

    Rail pressure sensor signal feeds to both RA****0 and engine ECU.So that rail pressure is monitored in real time withut affecting engine ECU operation. 
    Measure the engine ECU *5V power supply for the rail pressure sensor
    Over-pressure warning
    Powered by 9VDC battery
     Battery low indication
     A full set of accessories, including harnesses for Bosch, Denso, Delphi sensors, and battery
The following common rail engine faults can be determined based on the test results by the RA****0 Rail Pressure Diagnoser
         Whether the ECU *5V power supply is normal or not
         Whether the rail pressure signal circuitin in ECU is normal or not
         Whether the rail pressure sensor has fault or not
         No sufficient rail pressure during the engine starts is an indication of faults on the engine fuel system, especially low pressure circuit or high pressure pump
