Answer
Hi Bob,
I have to admit some ignorance on which engine is used in the Eagle. Do you know the displacement of it?, and is it a Chrysler engine or a Jeep engine? I have info on the 3.0,3.3, and 3.8L V-6's used in Chrysler cars. It may well be that the Eagle engine controller uses the same self-read technique for obtaining any fault codes that the controller may have observed as is used by Chrysler cars. So that would be good to try.
Begin a readout as follows: Take your ignition key and turn the ignition switch "on-off-on-off-on" and leave it "on". Do this switching quickly so that no more than 5 seconds elapses. Then watch the 'check engine' light to begin to flash, pause, flash, pause, etc. Count the number of flashes before each pause and make a note of them in the order that they come. The last two flash groups will be 5 in each. Repeat the readout until you have the numbers accurately (the same result, two times in a row). Then pair the numbers two at a time in the order they came, to form two-digit numbers, for example the last number will be 55 which is the code for "end of readout". Then write back and tell me the other numbers that came out and I'll see if any of them are related to your problem.
