Our coach (2007 Beaver Patriot Thunder) has the optional electronically controlled shocks (Bilstein's) that have a sport and comfort setting controlled by a dash switch. The lights on the switch stay on regardless of the switch setting. Does anybody have any technical information on how they operate? I have a constant error light on the dash but can find no troubleshooting data. Contacted Bilstein but they said since it was an OEM supplied item only they cant help, REV group has not been of any help. Any technical data, owners manual, brochure, etc would be appreciated. Looking at the wiring diagrahm, which I do have, it appears the system is not as simple as I hoped.
