Airmatic issues
 

2003 E500 all four corners are down.
The suspension control module is not responding to the star diagnostic tool.
My mechanic is suggesting to replace the suspension control module

Ny question: If I pick up a used one from salvage yard..will it need some sort of programming? or it should be plug and play? Are these programmed to Vin#s?

Any help would be greatly appreciated.

Thanks
