Chrysler Repair: 95 cirrus limp mode, ccd system, cluster board

Question
Hey Roland i've asked you some questions before im glad your finally open for a question. Ok heres the problem a while back my cirrus starting going into and out of limp mode. I took it to a chrysler dealer. I told them why i had brought it and to check the trans for problems. later that day they called me and said they checked codes and erased them and now everything is fine. It wasnt two more times and still havent gotten it right. they said that a malfunctionig abs module cause interuption in communication with the ccd system. and the lastest is the circuit board behind the gauge cluster. they quoted me $600 and not for sure if it will work. i went to the junk yard and got an abs module and two circuit boards. abs works fine but neither boards got my car out of limp mode. i have gotten a 66 trouble code im going to attemp to go throught the wiring to see which module isnt comunicating, or if any wires are shorted. i've done physical inspections on all the modules and no cracked wires or damaged connections. What i would greatly benefit from is possibly a wiring diagram for my car, the ccd system, and if possible for the guage cluster board. i have been doing a lot of research and havent found nearly enough information to resolve my situation. any input would be greatly appericated.

Hi Daniel,
Thanks for the generous evaluation and nomination.
As I reviewed the two manuals I got into the details a bit more. The '96 Cirrus manual has quite detailed and spread out wiring diagrams that total about 55 pages just for the pcm system, tcm system, and gauges/cluster. And it doesn't have a page about how to deal with the 66 code. On the otherhand, the '95 Sebring manual has that page and while the diagrams are more condensed, there are some differences in the plugs and wiring assignments. So I read thru the 66 code troubleshoot and can summarize it this way:
See if the scan tool can communicate with the TCM via the data bus plug under the dash. If yes, check the 80 pin plug at the pcm; if no, disconnect the pcm plug and then see if the scan tool can communicate with the TCM. If yes again check 8o-pin plug; if no then disconnect the 80-pin pcm plug and measure the voltage on each of the twisted pair data bus wires at the underdash data link connector (I believe that these wires ar on pins 3 and 11 of that 16 pin connector, let me know if the connector is not 16-pin).
The voltage compared to ground on each wire should be 1.5 to 3.5 volts, and the resistance between the two wires should be 110-130 ohms. If not, then check the 60-pin tcm connector and the harness between the TCM and PCM. If that seems o.k. then replace the TCM.
If the voltages and resistance check out, then reconnect the PCM plug and disconnect the TCM plug.
Then repeat the voltage and resistance measurement at the data link plug.  In no good then recheck the TCM plug and if nothing wrong found replace the PCM
If voltages are o.k., then still consider replacing PCM if plugs and harness seem o.k.
It is not all that helpful except for doing the voltage reading on the data wires and their interwire resistance measurements.
In light of all the copying and mailing (total cost will probably approach $5), I would recommend you do the voltage/resistance measurements and see what you find before I do the copying and mailing.
Let me know what you learn and decide then if you want me to do the copying.

Hi Daniel,
I have two manuals that might be helpful:
A '95 Sebring manual that has a single page fault tree for the 66 code that you can walk thru for the 2.5L V-6
A '96 Cirrus manual that had the wiring diagrams for the cluster and abs system.
It costs me 7 cents per page to copy and so doing that and postal mailing to you might come to somewhere in the $2-3 range. Let me know a postal mailing address and I'll get them off to you. You can send me back some postal stamps to reimburse my expenses when I have sent you the pages and you have them.
Roland
