# Service bulletin B511722

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.

- Type: Service bulletin
- NHTSA id: 10227551
- Published by NHTSA: 2022\-12\-12
- Manufacturer's number: B511722
- Manufacturer's date: 2022\-10\-01
- NHTSA component: FORWARD COLLISION AVOIDANCE; VISIBILITY; LANE DEPARTURE; STEERING; ELECTRICAL SYSTEM

## NHTSA's summary

Due to the semiconductor supply, the Local Interconnect Network module in either of the exterior mirrors was switched to another controller. That one provides an imprecise voltage measurement, which the main controller interprets as a fault. For the driving cycle, the customer may lose the display in either mirror and the Lane Change Warning function and, if installed, other functions such as\- Side collision warning; Lane Change Assistant; Steering and Lane Control Assistant; Emergency Lane Assistant Hands Off 60 Assistant.
