Question 2007 Mountain Aire airbags on rear not airing up

[bob5183]

Im in Yuma and parked here till april but my rear airbags arent inflating. ive played with the air break etc. front goes up no problem but back not. A tech came out and diagnosed as solenoid issue but he never came back. so im doing it myself. What tools will i need and where is the solenoid located?

Had similar problem - reach out to Valid who make the air leveling system. In my case the rear controller was reporting offline on the touch panel by the driver's seat (with error code that shows up on LED's. Valid said that 99.99% of the time, the only reason the rear controller is offline is no power. I was able to confirm there was no power at the controller (on the connector) and then traced back to find a EATON Rear PDM failure. I bypassed the PDM (with an external fuse!!!) to get power onto the wire to the controller and the system aired up as soon as I started the coach. In the end, I drove fro California to Gaffney and they replaced the PDM (at my cost)

The people at Valid are excellent and very helpful.
My fault was the junk Eaton PDM that Freightliner installed.

No problems since.
