# Service campaign N252510321

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

Certain vehicles will receive a software update to add to the existing Check Engine Light a Driver Information Center \(DIC\) warning message if DTC P0016 sets. Dealers will reprogram the Engine Control Module \(ECM\). Owners who have accepted applicable terms and conditions will have the opportunity to accept these software changes using wireless over\-the\-air \(OTA\) technology without having to bring their vehicle to a dealership. Alternatively, owners may have their vehicle serviced at a GM dealer to receive these software updates.
