Forget what I just said about the diagnostic code not working. I tried again and it worked. The first time I had the engine on. I read over David's post again and noticed he said to have the engine off. I got the numbers but have no idea what to make of them. Here they are.
41.6, 41.7, 41.9, 45.1, 45.2, 45.5, 45.6, 45.7, 45.8.
I put periods where the LCD displayed the symbol for degree (that little circle). From start to end, those are the exact numbers that come up. No more no less. Let me know if anybody knows what they mean.
