I looked up the code and it says:
Electronic Level Control Exhaust Valve Short to Ground/Open.
Does anyone know what to do about fixing that?
On www.gmpartsdirect.com, the part number for the compressor is 22120632 and the air dryer part number is 22153443. If you talk with a dealer, you're looking for the Electronic Level Control compressor and air dryer. I don't know if the part numbers are the same between the web site and a dealer's information. (anyone else care to clarify this?)kwalker1 said:I have the same code on my 96 Seville, I tried finding the parts you recommended but have had no luck. Does anyone know the actual part name and possibly part number for the ELC pump?
It won't make it run any better, and it probably won't affect gas mileage at all. The Electronic Level Control system adjusts the rear suspension height by pumping in or releasing air to compensate for changing load, etc. If it's not working, which is indicated by the RS0038 code and several others, it's possible the rear of the car would sit very low if you have a lot of weight in the back seat, trunk, etc. If the rear of the car is sitting low, the front may be sitting high, and that could affect gas mileage to some degree, but I doubt it would be very noticeable. The suspension position is used along with lots of other inputs by the Northstar system computers to determine things like power steering assist rates, shock damping rates, etc. So, because the ride height is affected by lack of ELC compensation, there would be some kind of weirdness introduced into the ride control system, but I don't know exactly what would happen. I drove my '96 SLS for over a year with the problem and noticed some difference when I fixed it, but it wasn't anything major.Cyberdan3 said:I had this same code in my history in my ECM. What exactly is this going to help with? My car runs fine now, so how will i benefit from this?? Will I get better gas mileage??
