maybe it has the performance chip!

lmao.

What you've described is the case with the PCM, not the CCM.

now im confused lol the picture diagrame on page 2 says ccm,thats what im talking about

 

[thefleetwoodguy]

93 has its own, 94-95 share the same an 96 is different.... from what i was told,you probly learned something new the fleetwoodguy:highfive:

ok you dont seem to be listening very well we are trying to help you,
one more time here we go, shouting so youll hear, THE CCM IS THE SAME (#_(^ing part!
you should learn the difference between CCM and powertrain control module pcm
the ccm is located in the trunk

not behind the right side kick panel, in 93, or under the airfilter 94-95-96 (pcm)
that being said, I appreciate you trying to teach me something about the cars Ive been working on for the past 7 years www.thefleetwoodguy.com, now you have heard it from jayoldschool,turbojimmy and myself, that pretty much sums it up
why dont you post some pics so we can make it clear for you, :thepan:

 

[85 FLEETWOOD COUPE]

the ccm is located in the trunk behind the seats, ok then the plugs are different 94 and 96 are not enterchangable, im not talking about the pcm.

Here:

in the picture above the 96 model c1 & c2 plugs do not plug in the 94 model ccm

 

[thefleetwoodguy]

if youd like I could sell you a ccm with a bypass resistor, its all plug and play er drive......
the performance chip is:devil: extra!!

 

[85 FLEETWOOD COUPE]

i dont know if you was being serious or you are messing with me?:bonkers:

 

[thefleetwoodguy]

listen this has been my job for the past 7 years I dont fk around I have used 96 ccm in 93's used 94's in 96's and every other combo possible the plugs are not different, have you tried to plug it in, take a couple pics of both ccms so we can get to the bottom of this
again there is no difference unless you have a 1 of 1 special built fleetwood that know ones ever heard about
seriously take a picture of both ccm's next to each other

 

[85 FLEETWOOD COUPE]

ok i got you i will take pics tomarrow or this weekend since im off,thank you

 

[thefleetwoodguy]

im sure when you get in ther youll see what we are saying is true, it looks like the diagram you posted the plugs may look different but thats a sketch when your under there just plug the 94 ccm in and then take a pic......youll see......good luck Jimbo

At the risk of beating a dead horse, the same exact picture appears in both the '94 and '96 factory service manuals. The description and operation of the CCM is the same, word for word, in both service manuals and (again) the connector face diagrams and wire pin-outs are exactly the same. Last, the part number of the connectors themselves (the C1 connectors) are exactly the same. I checked the wiring diagram because I've had scenarios where the plugs are the same but the wiring is different year-over-year. Not that I doubted thefleetwoodguy, but I wanted you to be confident that there will be no issue with the '94 CCM in your '96.

All that being said, the connectors with the tiny pins can be tricky to get plugged in. Get inside the trunk with a flashlight and make sure you're lining them up properly. Just don't do it with any of your wise-ass friends standing around or you may spend more time in the trunk than you anticipated. BTDT.

I can tell you that the 94-96 CCm's are the same I just got one out of a 96 and put it in my 94. Also if you have the VIN for the NEW one you can call the dealer and get the resistance

 

[85 FLEETWOOD COUPE]

:halok im going to have to bow down to the row on this 1,you guys was right it did plug into place,i guess it was the pcm? but now since i had pluged up its still not cutting on,i dont know if this is any information but when i turn it in the on position the pass key light is on but goes away then when i go to start it while the starter is engaging the pass key is on but goes off in a few seconds? i didnt know if this was normal or not but wanted to share just incase,is there any thing i should check to why it wont cut on?? THANKS

Well the Central Control Module - CCM - is what you plugged in back in the trunk. The Powertrain Control Module - PCM - is up front under the air cleaner. The CCM is supposed to send a signal to the PCM once it sees the right resistor value. The PCM will then turn on the fuel injectors. If it's cranking and not starting, then it sounds like you still have a PASS-KEY II issue.

I don't know how the PASS KEY light in the dash behaves when there's an issue. The FSM doesn't really say much beyond the fact that if the CCM does not see the right value, it will store a code. The codes can be pulled via the HVAC module.

In theory, the '94 column and CCM should work together and the car should start. If both the column and CCM are out of the same car, it sound like the PASS-KEY wiring could be faulty. It's a fairly common problem. You may have gotten a defective ignition cylinder in that column. Bypassing the system seems to be the easiest way to get it going again at this point. If we assume that the resistance of your '94 key is the value the '94 CCM is looking for, I would bypass the system as described with the appropriate resistor.

If you do have a pass key fault, you should be able to wait 3 minutes and then the car will disregard the pass key system and it should start.

EDIT: The owner's manual says that if the car won't start and the PASS KEY FAULT lights up, that's an indication that the system is not seeing the correct resistor value. Curiously, it also says that the starter is disabled as well (i.e., it won't crank). The Factory Service Manual, however, only says that the PASS KEY system will disable the fuel injectors, not the starter.

great info so you are saying i would need to bypass it with the factory 96 resistance not the 94s right,if i do need the 96 i guess i got to go to the gm dealership then

Actually, I meant the exact opposite. The CCM is hard-wired to look for a certain value. Since you replaced the '96 CCM with the '94 CCM, having the dealer match the '96 VIN to the car's correct resistance value won't help. If you want to go to the dealer with your VIN and have them make you a key, you need to put your '96 CCM back in it. This might be the path of least resistance (resistance, get it? I kill me....).

 

[85 FLEETWOOD COUPE]

so if i get the 96 resistance i would need to put back the 96 ccm, so with both 94 ccm and column/key i could just get the resistance off the 94 then bypas it

Sorry - I inadvertently took you down the wrong rabbit hole. Using the '96 CCM is probably pointless. Since you currently have a matched set of key and CCM from the '94 and it's still not working, that points to the ignition cylinder in the column. So what I would do is determine the resistance of the '94 key with a DVOM and buy that resistor at your local stereo shop. Then install it in the PASS KEY circuit as previously described.
