# Service bulletin SB\-25\-16\-006

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.

## NHTSA's summary

On certain Cybertruck vehicles, the AC junction box to fast charge contactor HV harness might have a poor crimp connection, which may cause increased resistance and localized heating in the harness. If the ancillary cover is removed for other procedures, replace the AC junction box to fast charge contactor HV harness with version \-J or later.

## Other bulletins for the same vehicles and component

- [SB\-25\-17\-003](/bulletins/11014771.md), 2025-03-04, Service bulletin: ELECTRICAL SYSTEM. On certain Cybertruck vehicles, the left body controller's printed circuit board was misaligned with its heatsink, which may cause the board to crack when the enclosure is closed. This may lead to a graceful power\-off event.
- [UI\_a006](/bulletins/11012222.md), 2025-01-03, Over\-the\-air update: ELECTRICAL SYSTEM. Tesla identified a manufacturing flaw in certain Cybertruck vehicles. Driving range and performance can be impacted by this high voltage battery issue. Tesla is replacing high voltage batteries for impacted vehicles free of charge.
- [SB\-24\-16\-008](/bulletins/11012220.md), 2025-01-03, Service bulletin: ELECTRICAL SYSTEM. On certain Cybertruck vehicles, the HV battery ancillary harness may have been improperly routed, which might strain the harness branches and/or connectors between the High Voltage Controller \(HVC\) and Battery Management Boards \(BMBs\), potentially preventing HVC and BMB communication through one of the two harness branches.
- [SB\-24\-17\-004](/bulletins/11008821.md), 2024-10-09, Service bulletin: ELECTRICAL SYSTEM. On certain Cybertruck vehicles, the backbone harness Flat Flex Cable \(FFC\) might have been misrouted, which may cause damage to the cable.
- [SB\-24\-17\-004](/bulletins/11008797.md), 2024-10-09, Service bulletin: ELECTRICAL SYSTEM. On certain Cybertruck vehicles, the backbone harness Flat Flex Cable \(FFC\) might have been misrouted, which may cause damage to the cable.
- [SB\-24\-17\-004](/bulletins/11008773.md), 2024-10-09, Service bulletin: ELECTRICAL SYSTEM. On certain Cybertruck vehicles, the backbone harness Flat Flex Cable \(FFC\) might have been misrouted, which may cause damage to the cable.
- [SB\-24\-16\-007](/bulletins/11006909.md), 2024-09-04, Service bulletin: ELECTRICAL SYSTEM. On certain Cybertruck vehicles, a rework to the ancillary cover is required to prevent damage to or to mitigate impact from the Ancillary Bay Mid Voltage \(MV\) Header.
