It is showing RED. Initially it was WHITE but the AWD would'nt engage so, I took it out to clean the connections and in a matter of seconds after reinstalling it turned RED & has remained that way. The AWD no longer engages. Flushed the ATTESSA & installed new rotors & pads... no change.
From what I understand this is the source of my woes (Error code 13). Just need to know if they are rebuildable as I understand some units have remanufactured written on them. If it is, writeup instructions would be nice.
