Merry Christmas, Happy Hanukah, Happy New Year!
Recently I found 2 threads here which were interesting and helpful.
My TCS CTRL light was on when we bought the car late last summer. Seller claimed to have all parts replaced (with used, I think). Someone mentioned the TCS valve on the firewall and I found the hose from that to the TCS on the intake manifold was a bit tired. I replaced that and it seems to have fixed the problem of cutting out on long steep hills at
7,000 feet elevation. However, I will believe that after it has not happened for a few months.Townsend has a procedure for pulling codes with the check engine light. I seem to have the right diagnostic connector, but no check engine light! I have a TCS CTRL light and an oil pressure light (looks like an oil pitcher under the hood where the door open lights are). This is apparently pre-Trionic. It seems trionic started in 93.
Does this mean I cannot pull failure codes or reset the TCS CTRL light without a sophisticated instrument? What is the instrument and what does it cost? Is there a method of jury-rigging an LED and switch somewhere and getting the codes that way?
Also found a procedure for pulling codes from the ACC, which also malfunctions from time to time, blowing hot air when you want cold, cold when you want hot. This only works for the older models. How can one pull codes for the newer ACC?
Apparently the outside temp sensor for the ACC comes from the EDU (trip computer display). This was working (EDU, not outside temp) but shortly after we bought it its lights went totally out. Mile Hi Body Shop says it is very expensive to fix this and I cannot even see how to get it out of the dash. I do have a spare outside temp sensor (from a 93 - is it the same?) but cannot find where the darn thing is.
Of course, Mile Hi Body Shop also said the only way to fix the TCS is to upgrade it for $1,700 and it seems I may have fixed it for the price of
2 feet of vacuum hosem (still waiting for 2 months without cutout to be convinced).If the EDU/trip computer is not working is this a real nightmare? How do I get it out, what is the replacement cost (used, working)?
Thanks for any assistance,
Charles
