Yes all have been.

 

Mrsed, I have read in your post that you have worked on the RCM, replaced some fuses and resoldered some spots. However, I recommend you send an email to tighed@hotmail.com and ask him to repair your RCM. He wrote the thread on "Mystery No Start". He is a long time member here and has helped myself and so many others with correcting RCM problems. He will completely refurbish the RCM and make an improvement which allows the horn to be activated when the key is out of the ignition. It will cost about $60 which is about half the cost of a new RCM. He lives in AZ so expect it to take about eight days, but he generally completes the work in just one day and quickly turns it around back to you. The RCM plays such a huge part in so many problems, It really must be working at 100% all the time.

PS The ECM Engine Control Module, which on the Crossfire is by Chrysler definition the PCM Powertrain Control Module is a big deal to replace! You should not need to do that. It requires programing which only a very few are capable to do properly. Best to leave that thought out of your plans.

 

AS to the tire sensor; It will not shut your car down. Search TPMS Tire Pressure Monitor System in the search box upper right corner (use the google option by clicking the word thread) or see the index of Crossfire repairs in The TSB and Trouble Shooting topic for more info. There are some members who can program a new sensor to work with the car. I would trust them more than any dealer.

 

I would first get the RCM repaired or replaced. If the problem persists I would then contact one of these individuals who will sort out the problem and get it repaired:

Good Luck!

 

Thank you Zip439, I will email tighed@gmail.com and get the info to send the RCM. I am happy to not have to deal with the PCM, it did sound like a big deal. I appreciate the referrals for help, will contact them if the RCM repair does not fix the problem. I appreciate your help, it is my dream car and don't want to have to sell her!!

 

Sorry I wrote email wrong, tighed1@hotmail.com. Thanks

 

I have been overwhelmed at work, sorry I did not see your later posts until now. I think you are wasting a lot of time and money.
The following is too late for you, but others will read this and learn and avoid your jagged path.

• RCMs do all the stuff you keep typing about. MOST of us DO NOT have the skills to fix an RCM without a spare RCM to verify operation, which DJ does. I am convinced you have spent tons of time an money for no good reason. I spent 30 years in benchtop, component-level electronic repair, fixing an RCM would be easy for me - if I had a spare RCM and spare car to verify operation - I don't but DJ does. GET A NEW RCM NOW.

• One day, my RCM failed. Being a fourteen year member here, I knew what it was right away. The car was in the garage and all I wanted to do was move it, so no big deal. I ordered a new RCM from PartsGeek for $129 (I buy the SLK230 version as it's the same part with one fuse wrong, but it's cheaper -move the one fuse from the old unit and you are good). I shipped my old RCM to DJ for rebuild. THIS WAY, i have a spare. The new one came in three days, got car running. The fixed one was back in about ten days, I now have a spare - and I don't need no damn tow truck.

EVERY post you made in this thread past your first one, described a bad RCM. EVERY ONE. Sorry I was not around to see that. (The tire light was not part of this, but that's a nightmare for another thread.) Also, that air pump you changed was a waste of money, IMO. The air pump DOES NOT and WILL NOT make the car run worse or better. it's just there to treat the exhaust to reduce nitrous oxide emissions. MOST of the time, that pump is failing cause the RCM is not turning it on!

• The RCM causes all sorts of failures, you can loose your ABS/ESC, speedometer, air pump operation, fuel pump, engine cranking, all sorts of failures -the RCM is the car's "Power distribution and switching module", most critical systems are powered by it , so most critical systems can fail due to the RCM.

Most who post here KNOW this, they just don't SAY it - but the RCM is your FIRST STOP when almost anything fails -you put your spare in, and if things are not better, you go on from there. If you do not have a spare, you damn well better get one or you will be meeting tow truck drivers more than you want to. RCM's plug in, you don't even need tools (You already know that but I"m now typing for others who read this). The cost of ONE tow would buy an RCM in most cases. You need no "shop" or "mechanic", you don't even need US, you need a spare RCM.

 

Hay Mark we all are hard headed sometimes, in post 4 i said get a new rcm or mercedes k40 (same part)
oh again in post 8 i recommended get a new rcm,,,,,k40 mercedes name of it and today i spoke to her and she is either getting a new rcm or sending her's to tighted1 so we all learn something new every day. best of luck to her.

 

I am part of a cult on Facebook PREACHING TO ALL to order an RCM, know where it is, and know how easy it is to change.

They fail more than, I think, anything and they are EASY to change. Kinda funny, the other two modules are hard to change but they seldom fail. Seems like MB planned for this failure to be easy to fix, dont' ya think?
There is NO reason for people to be calling tow trucks due to an RCM, not now that we've all learned about this failure.

I know I come off rude sometimes, I don't really care. I care more about empowering the average, non-technical owner so they don't get stranded by a defect we all know about and that ANYONE can remedy on their own. NOTHING will make someone feel better than changing an RCM and seeing their car come to life right away. That feeling is not to be reserved only for us techies, gearheads or 'mechanics'.

 

I was in contact with tighed1 late this morning and my RCM will be in the mail to him on Monday!! Thank you Jim for talking with me this morning, it was very enlightening!! Thanks Pizzaguy and everyone on the forum for your help. It is greatly appreciated. I am looking forward to feeling better when I put in that RCM!

 

and we all hope that is the problem and that it works any you r a happy camper jim

 

He's still right, you should carry a spare.

 

Thank you D.J. Tighe and all the expert advice I received from forum members!!!!! I put in the refurbished RCM and now my coupe has no codes Now that I know it was my RCM I am going to order a new one for a spare. Would the best place to purchase from be, Needswings? When I receive it do I need to send to D.J or is it good straight from box?

Again THANK YOU very much, now I don't have to sell and can enjoy driving my car!!

 

I don't think ROb has them but I may be wrong. I ordered this one:
https://www.autohausaz.com/pn/136396...BoCGSMQAvD_BwE

There is ONE fuse on it that must be 20amp in our cars but is 15 amp in this module. Transplant the fuse from the old to the new (actually, mine runs with the 15A fuse, but just to be sure.....)

The new one needs no re-furb.

 

Thank you Pizzaguy!!

 

I went with this one on AMZN. When I inherited this car I bought new spares of RCM, and Bosch Crank and Camshaft position sensors. Recently I had a SKREEM issue that needed repaired but before I diagnosed that I replaced all three. That wasn't the problem so now I have the 3 "used" parts as spares in the car in a box under the passenger seat.

 

Thank you Deepsea21, I also replaced sensors that I am sure are still good so I also have spares and will be making up a "spare parts" to stay in my car
