I look on the dash and see SYS is flashing. Well, at least I know how to check that. It gives me a code C41 - "Loss of ECM serial data communications" That does not sound good at all! OK, don't panic. I tried reseating the Instrument Panel. Nope. What else might be different? Before I began, I pulled the airbag fuse since I was working around the steering column. I reinstalled the airbag fuse and all is well. 
I adjusted my tach and shut the Z down. I think I'm going to do something else for a while. Wow, is that weird. But, I'm thankful the problem is solved. |
So, you were able to dial the tach calibration in, yes? Congratz! The resistor on the ceramic substrate must have completely opened, or something, to have given you such an unusually high error %. (Sorry 'bout the "oh sheeeiiiiitttt!!!" moment! Think I would have had to go away to collect my thoughts after a moment like that as well!

Good job!
