Service bulletin TT941101

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.

Both of the fog lamps will illuminate as designed when the fog lamp is switched to the ?ON? position with the headlamps ?ON?.
