Service bulletin S-1680

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

Shorting Cap for Aftermarket Bendix® TABS-8™ Advanced Single-Channel Trailer Antilock Braking System (ABS) Module The initial release of the Bendix® TABS-8™ Advanced Single-Channel Module did not include a Low Pressure Warning Emergency (LPWE) configured by default. This aftermarket service kit is configured (by default) with LPWE. If replacing an older revision of the TABS-8 Advanced Single-Channel Module with the new aftermarket service kit, it will be necessary to add a shorting cap to the S-E connector input.
