Service bulletin 122-C4A5S-10

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.

Technical Background The garage do or opener does not recognize the vehicle?s Homelink system and will not respond. This symptom only occurs on MyQ branded garage door openers. Many garage door opener manufacturers have a MyQ product line. (See common logos in figure 1.) The garage door opener itself, and not the vehicle, must be resynchronized.
