# Service bulletin SS1033700

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.

- Published by NHTSA: 2020\-09\-04

## NHTSA's summary

Updated Service Solution for New Cascadia Cruise Control will Not Set. Service brake state change is required to set the cruise control. Since the CPC looks to the SSAM for service brake signal the SSAM must be sending a brake signal for cruise control to function. Replaces original Service Solution from July 2018.
