I was able to clear all of the codes on my first go around with the exception of Eb1 417 & Eb1 418
Then I hooked up the mono heat valve and searched for the two remaining codes (Eb 417 & Eb 418) but they were gone probably due to my reconnecting the valve, and the display read FF, I'm assumming that this means finished.
Upon completion of the above I am still hearing the operating unit intermittantly clicking every 5 seconds and likewise the mono heat valve under the hood. This clicking stops when I press the rest button but resumes when turning the rest of, the light on the rest button is of while the unit and valve are clicking and light goes on when rest is pushed on.

Steve and Dave, thank you so much for your patience and perseverance on this issue, and for the wealth of information on how the error codes are found and deleted on this unit.
Steve, the article in Importcar (April 2001) was fantastic, believe me when I tell you that I have a printed copy on file with the car papers.

Ok Gilly,
would you mind telling me were you go to buy your operating units?? Do you buy new or remanufactured?? I am searching for info on Beckman Technologies
