Service bulletin JLRTB02084NAS1

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

The trailer lamps may not operate as expected. The trailer turn signal indicator on the Instrument Panel Cluster (IPC) will not be illuminated if the trailer turn signal lamps are not operating. For all other trailer lamps, any failure can only be observed by a visual inspection of the trailer lamps.
