Official summary
Some customer's may complain that the blind spot monitoring (BSM) is not operating, and the key ON bulb check is OK with no DTCs stored in memory. This issue could be caused by mis-matched BSM modules, especially if the vehicle was recently involved in an accident or work was done on the BSM system. To check if this is the issue, refer to the Repair Procedure.
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.
