New air compressor new front valve block new relay and fuses. Still have the suspension fault kick on. What else can be going on. The new Air compressor want even kick on any more. It kicked on an ran to only lift the back up front didn’t even move. I’m gettin very angry and spending lots of money

 

Would help if we knew the fault message, at the very least. Right now your posted an angry rant. Cant help. Need details including brands of what you installed (OEM or something lesser).

 

What codes pointed to changing compressor and front valve block. You may have connected something incorrectly as well. Can always run compressor by jumpering the relay connectors. No power usually means the fuse has blown

 

I got the upgraded compressor and oem valve block. The fuses aren’t blown. I have even Changed the relay for the compressor air ride

 

There are no compressor upgrades, there are two styles. Hitachi and AMK. When switching and software adjustment is required. What was in there and what did you put in?

 

I just jumped the relay. The compressor kicked on. Where do I go from here

 

I put in the AMK
it had the factory one in it

 

Need info on what its doing. What does it tell you? HDC fault? Special Programs not available? Which icons are displayed?

This could be a battery issue, a tail light issue, a brake switch, a steering angle sensor....need to know more

 

says special system programs not available

 

I'm trying to determine if it could be non-compressor related.
