Epetsi Posted February 15, 2017 Report Share Posted February 15, 2017 Hello I bought cadillac seville sts 1998. But now when i start it says service suspension system. I read fault codes and i tried to remove them but it still gives these codes RSS C1712 / Left Front Damper Actuator Open Circuit RSS C1717 / Right Front Damper Actuator Open Circuit RSS C1738 Exhaust Solenoid Valve Short to GND I checked elc fuse and it is fine What should i check next?

rockfangd Posted February 16, 2017 Report Share Posted February 16, 2017 I bet someone changed out the front passive struts for standard struts and did not bypass the plugs for the struts. I have a set somewhere that plugs into the strut plugs that trick the system into thinking it has the passive struts. I opted to go with oe type struts though so I didnt need them. The dampeners are in the front struts toward the bottom and have a 2 pin plug to them. The last code is likely a problem at the compressor. They were common to getting water in them and corroding the exhaust valve. Not a easy fix without swapping out the compressor. (trust me I have tried) Welcome to CaddyInfo GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
Epetsi Posted February 16, 2017 Author Report Share Posted February 16, 2017 Thank you, that helped much! is there way to bypass exhaust valve? Link to comment Share on other sites More sharing options...
rockfangd Posted February 17, 2017 Report Share Posted February 17, 2017 no The exhaust valve releases the air from the system when a load is removed and at the self test when the key is cycled. A bad exhaust valve will cause a high riding rear end ,(unless the system is clogged or has leaks, then it will just leak out rather than exhausting) GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
