## 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.
- [SB2233005](/bulletins/10235001.md), 2023-04-24, Service bulletin: ELECTRONIC STABILITY CONTROL:AUTOMATIC \(ASC\); POWER TRAIN. 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.
- [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.
- [SB\-19\-20\-003 R2](/bulletins/10181263.md), 2020-10-19, Service bulletin: ELECTRICAL SYSTEM; AIR BAGS. On some Model 3 and Model Y vehicles, the Occupant Classification System \(OCS\) signal might be affected by electrical interference in the seat harness, causing the airbag indicator to display on the touchscreen.
- [SB\-20\-44\-002](/bulletins/10178417.md), 2020-08-10, Service bulletin: EQUIPMENT; ELECTRICAL SYSTEM. Some Model Y vehicles were manufactured with a charge port busbar safety cap and/or PE \(Protective Earth\) busbar that might not meet internal specifications, resulting in intermittent vehicle charging capability.
- [SB\-20\-16\-004](/bulletins/10177031.md), 2020-07-06, Service bulletin: ELECTRICAL SYSTEM. Certain Model 3 and Model Y vehicles may have a loosened fastener inside the HV battery assembly, which could cause the HV battery to power down.
- [SB\-20\-10\-001](/bulletins/10177029.md), 2020-07-06, Service bulletin: EQUIPMENT; ELECTRICAL SYSTEM. Some Model 3 and Model Y vehicles might have a charge port door that is overflush \(protrudes in comparison\) to the LH taillight assembly.
- [SB\-20\-17\-006](/bulletins/10177028.md), 2020-07-06, Service bulletin: ELECTRICAL SYSTEM; LATCHES/LOCKS/LINKAGES:HOOD:LATCH. On certain Model Y vehicles, the hood latch actuator connector wires are installed in the incorrect position, causing the hood latch to open upon vehicle wake up; this will prompt a driver alert and prevent the vehicle from switching into drive mode until the hood latch is closed.
