Service bulletin TSB220232

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

This Technical Service Bulletin describes the recalibration steps for the software logic and calibration values of the Load Based Speed Control feature within the engine control module calibration which may interact with OEM Load Based Speed Control in an unintended manner, resulting in low power. This is an update to a previously submitted communication.
