As soon as I reconnected the ISO A connector, I can hear a noise like either a fan is going or the CD drive is spinning. This noise continues even after I turned the power off. Is this normal? It usually shut off after a minute or two but this time it continues for more than 15 minutes and I finally pull the plug.

Another question, how important is it to delete the error codes? Do I need to have the dealer reset the unit after it has been unplug?\

BTW, the COMAND is still not showing on the cluster and disk read error continues. I am not sure it is the wires or the COMAND.

Thanks.
