I have a few minutes so I might as well update what happened Saturday.
I got a notification while I was at work that the automatic suspension control module was delivered. Soon as I got home I couldn’t wait to get that installed and programmed to see if it fixed my issue.
I first hooked up the scanner and checked the software and calibration identification numbers on the old unit.
Then I plugged the Tech2 into my laptop and went to the GM website and downloaded the only software I could find for this module. The calibration number was different but it was the only thing I found that was for this module.
After I downloaded the program I swapped the old ASCM for the new one. Then I removed the relay for the compressor because I wasn’t sure what it would do and I didn’t want the compressor to run while I was downloading the program. Not sure that it would have but just as a precaution I pulled relay.
This was the first time I’ve ever used the Tech2 to program a module and it was fairly easy but at the same time I was afraid I would brick this module.
After it did its programming I turned key off and plugged relay back in. Scanned the info on the module and it looked like it worked.
But the compressor didn’t run. I pulled the codes and it had one stored for compressor relay fault. I cleared the code and compressor ran.
I pulled up the data and all my ride height sensors looked good, same data as the old module anyway. Then I commanded compressor on and watched the air pressure sensor and it read 0 and started to rise. Awesome! Before I was seeing 189psi all the time no matter what I did.
So now I have no codes, service suspension light is off. no Air bag message, and now just waiting to get this rim repaired so I can drive this thing and see how them struts feel and also can’t wait to hear no rattle in rear from that bad sway bar end link. So glad this is fixed and kicking myself for not doing it sooner but I really haven’t had the time.
