Official summary

TT: The blind spot monitor (BSM) sensor angle inspection is used to confirm that the BSM sensor is within the specified angle before performing axis beam adjustment. When used in conjunction with the repair manual, these BSM tips leverage SSTs and readily available tools to support sensor angle confirmation in varying shop environments.

Vehicles covered

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
