# Service bulletin SB2233001

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: 10210723
- Published by NHTSA: 2022\-05\-02
- Manufacturer's number: SB2233001

- NHTSA component: ELECTRONIC STABILITY CONTROL:AUTOMATIC \(ASC\); POWER TRAIN

## NHTSA's summary

Some Model S Palladium and Model X Palladium vehicles were built without a hydraulic control unit \(HCU\) wake\-up line, and in rare circumstances, braking and stability control related alerts may appear on the instrument cluster and touchscreen during the vehicle power\-on process. Such faults can typically be corrected and the affected functionality restored with a vehicle power cycle.
