I have now been after this problem since the summer and i've exhausted every lead i can possibly think of.
Over the summer I did a 5-90 upgraded battery kit and after i did that this is when the problem has surface.
When I start up the jeep the following things happen
I get volts, gas guage and temp gauge to work.
My check engine and airbag lights are on and i also have a no bus in the odometer reading area
And my tach, and oil pressure and I believe speedo all dont work.
Also if you put it in drive and try to drive it sounds like your attached to a building, im guessing because the tranny isn't shifting b/c its in 3rd. But if i manually put it in 1 it takes off no problem.
I have gotten the FSM and i've exhausted every lead in that book. I went to the guage cluster portion and did EVERY step they said, and everything check out ok time and time again. I've probably done it about 5 times just to be sure.
Then i thought maybe it was the ecu, so I replaced that, still a no go.
Thought it could be the guage cluster itself, had another one laying around that wasn't it either.
Then i started to look at the pinouts of the ecu. Saw theres a ccd bus pin on the ecu. I follow that through the wiring diagram which leads you to both the data link and the guage cluster. Checked that for continuity that checked out.
I don't know what else to do. I havn't drive my jeep in a year and my wrx is on its last leg. If anyone has ANY ideas please share.
Thanks
Matt
