Yeah im sure. 5 long flashes and 1 short one. I read on another site, that a guy with an R6 had the same code (51) and it also was not in the service manuel. It turned out to be fan motor/relay. I find it hard to believe that the codes or ecm are the same. Thou i will test the fan and inline circuit breaker tomorrow.

Called a dealer and will know in a bit...will post answer when i get the info. It will be for a 2009 model because i dont know your model year. But from 2006 to 2011 i think they are all made the same so should be same problem.

Thanks alot for spending the time to help me. When you say bullet connecters, do you mean the in line circuit breaker connection that goes to the relay?

Well im sad to say it still doesnt work. I checked all connections, tested the fan, the circuit breaker and even applyed power to the relay and checked for continunity. Im at a loss, not sure what to try now. I hate to take it to the dealer. Any other ideas? Is there a way to test the wires between the relay and the fan? Any help is greatly appreciated.

PITA electronics. I dont think it would cost you anything to have it tested. Dealers want the money from the new parts your going to need if somethings wrong. I would call a couple dealers and ask them how they would charge to test your relays...Im also thinking the fan might be fried/no good anymore.

Yeah im kinda at a loss. I direct wired the fan and it came on, then removed the relay applyed power and it was opening and closeing. I also pulled out the circuit breaker and tested it. What else is there? I looked over the wires and didnt see anything broken or burned (Barker Duals). Is there a way to remove the relay and apply power to its connection and start the fan? That way i know the wiring is good between the fan and relay

Your best bet is to start a new thread about it. Members that have had similar problems and/or know the relays better than me will chime in and help you.
