If by "computer" they mean the ECM, I was not aware that has any connection(no pun intended) to the Comfort System.
The 2006 Service Manual has step by step trouble shooting directions with pictures in it.
Telling you that you will not feel heat above 60F pertains to the seats & passenger back rest and is a correct statement.
This may sound crazy but, remove the seat and remove the passenger backrest and make sure they are both connected to the harness. They can unplug!
Most of the failures are one of the grip heaters. Everything must be working or nothing works. No seat heat without grip heat and vice-versa.
Once you have confirmed everything is properly connected, trouble shooting the grips is the best place to start.
You need a service manual and a few "tools" to do this.
Unless you have a Honda dealer within reasonable distance from you that really markets Wings and accessories for them, I doubt you will find a tech that knows anything about the comfort system.
When mine failed, I even had one service manager tell me the passenger backrest did not have heat in it!!!!!!
The heated grips work great! The heated seat was a total waste of money. Not much heat in cool weather and none can be felt in cold weather until one does a mod to the seat wiring(but that will definately void the warranty)
