B0097 is the second right-side crash sensor. Mitsubishi fixes it at the right B-pillar, lists it as B-PILLAR SAT SEN RH and gives Right Side Restraints Sensor 2 as the J2012 name. Only subtype -55 appears there: the unit flags, after two seconds with the ignition on, that the stored configuration does not match the fitted sensors. Honda's request AER17060A confirms the numbering with B0097-87, meaning the second right side impact sensor has gone quiet on 2016–2017 Fit and HR-V cars. On a pillar an acceleration satellite is the usual choice; Bosch fits such units to B- and C-pillars, sills or seat cross members. Not every maker uses this code: FCA reports its right B-pillar acceleration sensor on the 2025 Ram 1500 as B2764, and Saab 9-3/9-5 use B0097 for the driver belt buckle switch circuit. While stored, the airbag lamp stays on.

Likely causes

Airbag unit configuration not matching the fitted sensors, e.g. after unit replacement (Mitsubishi subtype -55)
Plug at the right B-pillar sensor loose or damaged after trim or seat belt work
Right B-pillar sensor sending no signal (Honda subtype -87)
On Saab 9-3/9-5, driver belt buckle switch circuit fault (different meaning)

Symptoms

  • Airbag warning lamp on
  • Right side impacts near the B-pillar are detected only by the remaining sensors
  • Safety note: airbag system; disconnect the battery and keep the wait time before removing pillar trim, specialist workshop only
