I have a 2005 Crossfire Roadster with 28,000 miles on it. I replaced the CCR last year because the car won't start. After replacing the part the ran great. I just went to get the car inspected and it won't pass. Is it possible that the CCR is defective and needs to replaced again?

 

What is a CCR?
Why will the car not pass inspection? Bad windshield wiper or brakes? Maybe you just need to drive the car for a couple hours around town to get it to come into inspection compliance.
Go to an auto parts store and have them scan the car for DTC codes and write down the numbers. Don't come back here and tell us its this or that module or sensor. GET the exact codes.

 

First off, it doesn't show any code numbers. Secondly CCR is the Computer Control Relay. Thought you would have known what the CCR was, guess I was wrong. Thirdly I have been driving it around, is 200 miles enough. Fourthly, are you having a bad day to respond as you did.

 

I believe something is getting lost in the translation. When you are talking about the "CCR", is that the box with the fuses on the top located in the electronics box next to the engine? If so, we refer to that as the "RCM" (relay Control Module). See picture below.
When you went for inspection, did they give you a sheet explaining why the car failed? In New Jersey, they give you a sheet with the reason for the fail. Since NY is like NJ and all they worry about is your emissions, I would guess the car failed for an 02 sensor or pollution related item. You can have a big auto parts store like Autozone or O'Rielly's scan the car and see what they come up with. They usually do that for free.
The more information that you give us, the easier it is to help you.

 

Thank you for the response. Yes, it is the RCM, the part reads Computer Control Relay. The shop I go to doesn't use a DTC, the device they use now doesn't show codes just that you failed, go figure. Guess I'll have to find a shop that has a DTC device. Thanks again.

 

I think it is you that are having a bad day!

 

So, back to my original question, I have a 2005 Crossfire Roadster with 28000 miles on it and runs great. I changed the RCM last year when the car wouldn't start. Everything is working on the car except the Computer module under the dashboard, it isn't reading any fail codes. Does the RCM control the computer module under the dashboard to let you know what the code is for inspection failing. Thanks for any help!

 

You are doing it AGAIN. There is no "Computer module under the dashboard". You are asking technical questions but not using proper terminology and you think WE are the problem?

The one thing "under the dashboard" is the airbag module (hidden under the console just below the ashtray, etc.)
Another is the TCU "Transmission Control Module" under the passenger's feet (automatics only)
I can't think of anything else. I can see them failing it for an airbag code, but they did not fail mine here in Texas and my airbag module is D E A D and has been since 2016.
Now YOU are in New York, I"d bet they are worse than Texas - so who knows? Try to find out what failed. Here in Texas, they give you are three page report, generated by what failed. Both my car and bike failed this year, Truck due to a bad O2 sensor and car cause I had just changed the RCM earlier that day. (YES, changing the RCM or even unplugging it will cause a "Not Ready" which is a FAIL.)

So, did the car fail due to a code or did it fail due to not being "ready", that is, not being driven enough since the battery was changed/disconnected or the RCM was unplugged (either of which wipes out the emissions memory)?

 

My intent is not to annoy anyone. If I'm not using the right terminology, I'm sorry. So let me try again. The On-Board Dianostics port under the dashboard on the driver side is not giving me a reason why it will not pass NYS inspection. No code indication. I have put over 250 miles on the car since it first failed and have brought it back 5 time to the inspection station to no avail. I did change RCM 6 months ago and the only thing I wanted to know is, in your opinion does the RCM have anything to do with the information that the OBD-II reads. If I'm not expanding myself correctly, I'm sorry, just looking for advice.

 

I'm trying to help, so let me ask you these questions.
When the tech says that your car failed, did they tell you what they were failing you for?
Are you going to a state inspection center or a private one?

I've been going to a NYS Inspection shop; he is also the mechanic I use for other repairs. The State device he uses is for all NYS inspections. I'm over his shoulder when he tests the car and it indicates x for everything, but no code appears. I'm trying to make an appointment with a Mercede's mechanic to see if he can figure it out. Thank you again for any advice.

 

Strange he would fail you and not tell you for what especially since it is also a safety inspection? Can you take it too a different inspector?

 

Having lived in NY I know they are privately owned gas stations that do inspections. Are you saying when he connects it to the state machine it can not read the car? Do you know if he has chosen the right car? Maybe he would need to choose a Mercedes 2003 SLK320. Have you gone to just an auto part store and had them scan the car for you?

 

While you may not be getting any codes out of the on-board diagnostic port, the piece of paper that the inspector has given you that tells you the car has failed the inspection will have the reason for the failure listed on it. That is the piece of information that the helpful forum members are looking for. They need to know why it failed, before they can help you. If you cannot determine the reason, take a picture of the failure report and post it.

 

Just got my car back and no one can figure out what is wrong. I've been told that the computer needs to be rebooted, so I'm stuck with no inspection because the NYS device can't read what is wrong. I made an appointment with a Chrysler Dealership but I don't think they've worked on a Crossfire. Mercedes won't touch it either. Trying to find someone on Long Island that has worked on/or is familiar with the problem. Any suggestion would be greatly appreciated.

 

Take it to an Independent Shop that works on Mercedes and ask them to scan it.

 

That's exactly what I did, and he suggested bring it to a Chrysler dealer. He ran a test on the computer and wasn't able to get a read out. Everything is working and the car runs great, I'm lost.

 

You make it sound like the diagnostic port is not working.
I'd go get a cheap code reader and try it myself. If an off the shelf code reader can talk to the car, they go try another shop.
If the code reader cannot communicate with the car, it's time to fix what ever is wrong with the diagnostic port.

But you MUST determine what is really wrong here, IS there a problem with the car or not?

 

If the car runs fine, the only "computer that needs to be rebooted" is the one the shop is using to communicate with the car.
