Hello,
Does anybody know how to read the Diagnostic codes that the
little "secret" functions of the 540's computer will tell you? It
used to put all 0's but now it puts 1 D7 81 000. I wonder if this
related to my recent problem with lights on the check control area,
or maybe the fact that recently, the temp display has twice
displayed way over actual?
Thanks,
Richard
