# Service bulletin SB\-20\-16\-004

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.

## Other bulletins for the same vehicles and component

- [SB19\-20\-003\-R3](/bulletins/10247400.md), 2023-12-18, Service bulletin: EXTERIOR LIGHTING; AIR BAGS; ELECTRICAL SYSTEM. On some Model 3 and Model Y vehicles, the Occupant Classification System \(OCS\) signal might be affected by electrical interference in the seat electrical harness, causing the airbag indicator to display on the touchscreen.
- [SB\-21\-18\-002\-R6](/bulletins/10226577.md), 2022-11-28, Service bulletin: ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY THERMAL:MANAGEMENT:SOFTWARE. Certain Model 3 and Model Y vehicles may be equipped with refrigerant pressure/temperature \(P/T\) sensors in the heat pump that can fault over time.
- [SB2233005](/bulletins/10214117.md), 2022-06-13, Service bulletin: ELECTRONIC STABILITY CONTROL:AUTOMATIC \(ASC\); SERVICE BRAKES, HYDRAULIC:POWER ASSIST:ELECTRIC:CONTROL MODULE; ELECTRICAL SYSTEM:WIRING. Some Model Y vehicles were built without a hydraulic control unit \(HCU\) wake\-up wire, 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.
- [SB2233003](/bulletins/10213755.md), 2022-06-13, Service bulletin: ELECTRONIC STABILITY CONTROL:AUTOMATIC \(ASC\); ELECTRICAL SYSTEM. Some Heat Pump Model 3 vehicles were built without a hydraulic control unit \(HCU\) wake\-up wire, 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.
- [SB2117007](/bulletins/10212802.md), 2022-05-31, Service bulletin: ELECTRICAL SYSTEM. On certain Model S, Model X, and Fremont\-built Model 3 vehicles, the Printed Circuit Board \(PCB\) for the RH side repeater camera may lose electrical continuity over time, resulting in premature failure of the camera.
- [SB2117006](/bulletins/10212801.md), 2022-05-31, Service bulletin: BACK OVER PREVENTION; ELECTRICAL SYSTEM. On certain Model S, Model X, and Fremont\-built Model 3 vehicles, the Printed Circuit Board \(PCB\) for the LH side repeater camera may lose electrical continuity over time, resulting in premature failure of the camera.
- [SB2217004](/bulletins/10210726.md), 2022-05-02, Service bulletin: ELECTRICAL SYSTEM. On certain Model S, Model X, and Fremont\-built Model 3 vehicles, the Printed Circuit Board \(PCB\) for the LH and RH side repeater cameras may lose electrical continuity over time, resulting in premature failure of the cameras.
