Service bulletin CSC-220420

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

Dealer letter for CSC-220420. With some models and features, the Display Commander (LCD screen) for the In-Command system, may exhibit erratic readings on HVAC and/or lose communication with components. This is caused because Keystone may not have installed an End of Line (EOL) Resistor in the “Gateway” located in the Roof A/C.
