97seville Posted December 20, 2007 Report Share Posted December 20, 2007 97Seville SLS original struts/air shocks DTC C1737 Exhaust Solenoid Valve Short to Battery put car up on ramps...pump runs and shuts off when at proper height. With one person extra load on bumper works fine...with 2 people pump does not shut off till load is removed. Would this code set if the pump runs too long without getting to the height it is shooting for? Anyone have this code before... Link to comment Share on other sites More sharing options...
Cadillac Jim Posted December 20, 2007 Report Share Posted December 20, 2007 It sounds to me like it's got a small leak. Check the hoses and fittings. If they are good, then it's probably a pinhole in one of the air bags on the rear shocks. If the damping is still good you can try to patch it because they are $400+ apiece. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

Air bags look "dry rotted" cracked...normal for age...but may have leak. there are small hard lines that go to the air shocks...what are the larger soft lines for?...where to they go? sometimes the rear end is low./rough ride How can you tell when the front struts need to be replaced? does the front end have its own compressor? Front ride is rough also. No other codes Link to comment Share on other sites More sharing options...
Cadillac Jim Posted December 20, 2007 Report Share Posted December 20, 2007 I would check the C1737 code and fix the wiring to the exhaust solenoid. It sounds like it's shorted to the battery, which could be your "leak." Once that is fixed you may not have a problem. The hoses on the upper part of the rear shocks are the air hoses. The exhaust solenoid is on the compressor, and is an auxiliary function of the compressor relief valve. The connectors on the lower part of the shocks are the variable damping control connectors from the ride-sensing suspension (RSS). The front shocks are the struts and they don't have air bags. They do have electrical switching from soft to hard damping as part of the RSS. Give them the front fender shove test like any other front shock. They are more expensive than the rear shocks, and the scope of a DIY strut rebuilding and replacement job is pretty advanced. Do a search on this; Bodybyfisher has done this with his car with good results, but you may not be prepared to take on what he did. Also, he had adequate workspace inside, which is really important in the wintertime. If the rubber on the rear shock air bags is weathered and cracked, you might try a reconditioning spray. I would check with ADAP or Pep Boys but others here may have a better recommendation. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
