Service bulletin 844

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

TECHNICAL SERVICE BULLETIN RE:HYDRO-Trap Kar-Tech Remote Dear HYDRO-Trap Trailer Owner: This Technical Service Bulletin is being sent to you as an owner of a Wilson trailer with a HYDRO-Trap system. Your HYDRO-Trap opening system was provided with vendor supplied manual switches on the side rail of the trailer, and a compatible Kar-Tech remote control. This remote is paired to a receiver which controls the trap operation on your trailer. This pairing is through a preexisting frequency from the Kar-Tech manufacturer. CAUTION: A potential issue exists with the Kar-Tech remote frequency pairing, which may inadvertently be paired with another trailer’s receiver. This may cause an issue where the use of your remote may cause the trap door on another trailer to open if on the same pairing frequency and within the frequency range. Do not use your remote to operate your trap doors until you have performed the correction below. CORRECTION: Please see the enclosed instructions on how to reprogram your Kar-Tech remote and re-pair it with the receiver on your trailer. There is also a QR Code in the lower corner of this letter that you can use to view a video of the process.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
