Service bulletin TSB-039
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
A change can be made to the routing of the pneumatic actuator activation circuit so that use of the emergency air supply side will bypass the front and rear master control valves, the actuator control valve and much of the plumbing connecting these valves. By making this change the probability of the emergency air supply feature working after an accident is greatly improved.
