Hi ..C1130 Code Air Spring Air Supply..Fault Code ?
But it doesn't specify which Spring or Part ?
Anyone know?
Thank you

 

No suffix? Either way its not an air spring issue, per say, its an air spring air supply issue - meaning the air supply to one or more spring seems to be problematic. Typically this is an inferred fault by the system, there is no hard detectable fault but the system watches how everything works. So lets say its commanded to raise the vehicle and proper pressures are reach, the rear goes up, but for some reason one side of the front is slow. The system can tell by the sensor output and thus deduces there is a fault and throws a code.

So you could hav a very badly leaking bag, but thats usually another code since it can often even figure that out. Plus you would hear the bag leak. Odds are you have a line leak, which would be audible. A leak at a valve block, again should be audible. Or you have a valve block that is failing, this is common if the compressor has not been serviced and the dryer desiccant is now powered a bit and contaminating the system. The powder gets on the o-rings and creates internal leaks.

 

Thank you what would you have done to solve this?

 

Search/listen for leaks. Set the truck to different height modes and bounce it by hand to see if you can hear a bag leak. Soapy water sprayed on the air lines, around the compressor, etc. If you cant find a leak then I would consider rebuilding the valve blocks. A rebuilt kits is about $20 and cities of all new o-rings. Its not a terribly complex procedure and there are some write-ups out there that explain how to do it.

 

Thank you Dakota

 

Is there a way to Print this out that is readable.
Id like to Print it out and take it in to the mechanic but when I Print the normal way
off the iMac.. the letters print too small for anyone over 21 to see : (

 

When you select print, you can click "show details" at the bottom of the print panel. Then to the right you can blow it up percentage-wise. The problem is it will create a lot of extra pages as the text will run off the edge. Meaning you will have to cut/tape stuff to align it. Like how they used to make newspapers...

 

Dakota hi...I gave mechanic this print out and mentioned rebuilding of valve blocks..he said he can replace them ..they are not too expensive..
off the top of his head..is that true?

 

They are not terribly expensive. $100 to $200 depending on location. The front and rear are almost identical in design but NOT interchangeable! This is emphasized in the tech manual. The center valve block is pretty simple. Of course the mechanic will have to mark them up to make some profit on parts.

 

Dakota..thanks ..$100-200 each ? Plus labor? They would come from Atlantic British Thanks
