Help!!! service air suspension

[Piero]

i have Hummer H2 in Lithuania and seams 3 weeks appear always on the screen the text "service air suspension" and now i see that the car on the back side is quite down... what can be, what i should do? Here in Lithuania is quite difficult to find some service that understand about Hummer... ;-) Thanks for your help....

It could be your airbags, they do tend to get cracks and break, you could try ordering some, there are some writeups (and a youtube video I believe) on how to change them.

Alternatively you could just replace the air bags with springs, but then it would come down to finding someone with a tech II to reset the system to stop popping up the service air suspension message.

What is the connection between airbegs and suspencion? Even if airbags are brake(but i don't think so) why shouldn't work air suspention? i look well my car today and i see that back in the left side is very down,but in the right side is more up and even if I go around by car don't change nothing... maybe is not working air compressor... How to understand? I don't know,maybe someone can help me?

I was doing diagnostics,and they find the problem code C0626 (LEFT REAR POSITION SENSOR CIRCUIT PERFORMANCE)... And U1064 (LOST COMMUNICATION WITH BCMIDIM) ...What does this mean? What to do now? Thanks...

Sounds like your left airbag in your suspension is broken.

There are many more knowledgeable than me, however, being on the board a long time and reading several air suspension posts, and having air suspension on my H2 I can tell you it's normally not the air bags, but instead a bad sensor, or a loose or broken wire to the sensor, or mud and gunk on the sensor, or the sensor needs adjustment. As for your air bags, when I bought my H2 new the service dept said to spray them with Armorall three or four times a year and they would stay in good condition - so far so good!

On average if i see a left sensor code, the sensor is at fault. Right sensor code is typically wiring. Not sure why but thats been the average
