Have a 98 STS giving code in RSS C1738 I believe this means exhaust solenoid valve short to gnd. Where is this valve and where can I get it I calles my dealer & they gave me a part no that everyone else says does not exist plus they want $225 for it !!!!! Any help appreciated, Thanks
Thanks for that, I looked up that part on gmpartsdirect.com and it is the compressor head and they sell it for $96 !!!! but is that the right one as it says nothing about being an exhaust solenoid valve ?????
I had this problem on the air compressor for my old 94 Concours. It turned out to be a short in the wiring. The dealer wanted $600 plus to install a new compressor. I bought one for around $300 and still had the error code!
I took the car back to the dealer, and they fixed the short in the wiring.
To answer your question, the exhaust valve is on the cylinder head of the compressor, it's what lets the air out of the shocks.
I'd have the dealer check for a short before spending all that money on fixing the compressor or buying a new one! Don't make the mistake I did!
Caddy - Where was the short in the wiring? Where would this be located on a 99 STS? I'm having the same problem code, though I don't really have any problems to report for the actual operation of the vehicle.
