This is a 2001 unit. Try to key unit and it illuminates the odi and remains lit. The relays on the system card do not close. The rear facing card attached to it has a rapid consistent flash. The traction card led's flash when the key is cycled but then stop. It will very intermitently start up but we are talking every 300 key cycles. I suspect the system card after consulting with my Raymond buddies but no one can tell me for sure. i have the card on order but if you can tell me differently i would love to hear it.
