Cadillac Repair: 1999 Cadillac STS Service Suspension System, 1999 cadillac sts, cadillac sts

Question
Hello, about a month ago my Service Suspension System warning came on. It came on from time to time after that and I also received the Speed Reduced to 145 km warning. I took the car to the garage but they could not locate the problem.  The codes RSS C1711 and RSS C1712 History were found when the codes were checked.  I had recently put new tires on the car and had the shop do a front end alignment after these codes had come up.  They cleared the codes and I drove for about three weeks until the Service Suspension System warning came on again.  The same two codes RSS C1711 History and RSS C1712 Current were in the codes this time.  The Service Suspension System warning comes on now every time I start the car. Is it safe to drive the car without damaging any electronic modules and do you have any suggestions as to what the problem could be.  Thank you for your help.

Answer
You most likely have an open wiring circit at one of the wheels as this is very common when front end work or rear end work at the tires and wheels is performed as the electrical plug may have been disconnected and not reconnected and or it just needs to be unplugged and the electrical contacts cleaned and then have the check engine light turned off.

You will need, If necessary, Electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.  I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
