Collins TDR-90 Transponder Diagnostic Code

[FlyingFisherman]

Ran into a problem with #1 xponder on this unit. Hit the test button and it listed dIAG code #23. Problem is, the manual for the unit only lists 1-10 and neither 2 or 3 made any sense.

Anyone with a maintenance manual of some kind shed some light on this code?

Thanks!

My list of diagnostic codes ends at 10 also. I sent an email off to someone who should be able to provide an answer, if there is one.

Thx, Torqued.

The reply is in and the answer is..........no such code. There is probably an issue with the CAD-62 or the CTL. If you have a dual installation you may be able to swap them around to find the culprit.
