Having trouble with my instrument panel. A while back (as in more than a year) my fuel gauge went, then my speedo got funny off and on (real fun when you've got the cruise set at 75), then the tach became funny. Also less fun then squishing tadpoles having the disconcerting check engine light come on, occasionally popping back on at high RPM's shutting it down as the needle pops up to the red line. Last night the whole shebang went down, allthe gauges. Just displayed the air bag, abs, fuel, brake and engine lights. Odometer flashed and then displaye No buS or was that No bu5?

Sounds like a wiring harness going funny? a bad plug-lock under the dash? where would that sucker be?

 

My friend had a similar thing happen to an old buick. The dealer spent about a month trying to figure it out and finally determined it was a bad PCM. Do you have any way of chekcing yours?

 

I assume that pcm is power control module? No I do not have a code reader. Hoping to still stay on the knuckle banging myself any way. Miss my old '52 Power Wagon, that old thing you could fix with a rock.

 

i think ive seen no bus around here a few times and it always comes back as a bad pcm. yeah, its the power control module, your computer, whatever you want to call it. do a search on no bus. i'm sure you'll find lotss of info.

 

Garcias,
I had written that while patiently awiating the fabulous gift of the tech manual above.
Death to Chilton's, nice to have the real deal.
A bit scary, que no?
Stinkin' freakin' computers. Make my living w/ them and have come to the conclusion that Bill Gates is the prince of darkness, Makes Sir Lucas-Girling seem less annoying than a fly on your neighbor's windscreen.
