2002 Chevrolet Autoride Problem

[skigolfnut]

I have a 2002 surburban with autoride suspension, I noticed it not working the other day, I have followed the advice from this site to narrow it down, fuses are good, I put 12 volts to the black and red wire going to the pump and the pump works fine, no leaks it will stay pumped up for a while, I cannot get power to the pump? Is there a solonoid? I was reading earlier about a module upgrade by chevrolet dealer? Most of the problems I have been reading about are the compressor will not work, what to do if the compressor works but no matter how loaded it is it will not turn on?

 

thanks,

Here is the wiring schematic for the system. Have you used a multimeter to confirm you are getting power on the harness? If you have power, then the control module or load sensor(s) may be bad.

I took it to my chevy dealer service manager, he put the scanner on it and said everything looked good up to the compressor leveling module, he said he found a code for the exaust solenoid, he cleared the code but it kept tripping, he said he is about 90% sure to replace the compressor, that the exaust solenoid was on the pump,

I have a new compressor coming from Arnott, I will give it a try on thursday, I was told its not very hard to put in the replacement pump, any tips??
