Service bulletin 18158

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

18158 - Service Update. Certain vehicles may exhibit a condition where the Service Side Detection (SSD) message is displayed on the Driver Information Center (DIC) screen. This message is displayed in the DIC and does not reset until the vehicle has gone through an ignition sleep cycle. When the SSD message is displayed, the Side Blind Zone Alert (SBZA) system is not functional. Dealers are to update the side blind zone alert module with a new calibration file.
