Cadillac Repair: 1991 Seville-Service CCR System, Salt Lake City Plaintiffs forensic locksmith, Jackson

Question
Hello Rob,
Yesterday I drove over a speed cushion bump (slowly) and my exhaust slightly scraped the bump.There were four people in car at time.I have been over this speed bump many times before no problem.My exhaust was custom made two years ago and is maybe slightly lower than standard but has never been a problem before and still looks fine now.
This morning Driver Info Centre is coming up with "Service CCR System"( I think this message has come up before )
The rear of the car seems to be sitting about 1cm lower than the front ( maybe that is normal)??
Can you please advise what is involved in Service CCR System-is it a repair or replacement? If I needed new shocks can I replace them with basic ones as I assume the computer command ride system is pretty expensive??
I am from the Uk so mechanics probably have little knowledge of this system??
I've just been over the same speed bump again this morning with just me in car and fine,no scrapes.
Many thanks for any advice you can give me.
Andy


Answer
Hello,

Your CCR is not working and could be from a number of different reasons. Being in the UK, I don't know what your parts availability is and once diagnosed, could cost you a lot of money to repair.

Cadillacs and Lincolns are notorious for air ride leveling issues. We have better options to go after market to go around these issues.

Check to see if a local parts house has an after market air ride kit. Monroe among others in the US make the complete system including compressor for a fraction of the cost of factory.

Otherwise, you cannot ride over these speed bumps (that one of these days I am going to sue someone for, because of damage to the 10 herniated discs in my spine I have had previously due to getting rear ended at high speed from a school bus. These darn things cause severe pain just trying to go over them at the slowest of speeds)with the additional weight of people until you do something with the ride leveling or you will bottom out.

You could have a computer problem, sensor problems, compressor not working, air leaks.

Check an auto parts store and see if Monroe, Moog or other US brand names offer an after market alternative and I really want to know.

This info will help me when answering other UK questions.

Thanks.
