The front passenger airbag in the dashboard is normally dual-stage like the driver bag, but it also depends on occupant detection: FMVSS 208 allows it to be suppressed for small occupants and requires a readiness indicator that monitors the system. B0010 reports a fault in the firing loop of its first stage. Mercedes-Benz stores B001013 when the stage 1 squib of the passenger bag is open; Mitsubishi files B0010 under the passenger (assist) airbag module with several fault bytes. A suppressed airbag is not a fault and does not set this code; B0010 means the wiring or squib of stage 1 is electrically out of range. Typical spots are the connector behind the dash panel and harness routed past the glovebox. The passenger bag may not deploy and the airbag lamp stays lit.

Likely causes

Loose, corroded or unlocked connector at the passenger airbag module
Harness damaged during dashboard or glovebox work
Internal fault in the passenger airbag module (stage 1 squib)

Symptoms

  • Airbag warning lamp on
  • Front passenger airbag may not deploy in a crash
  • Safety note: do not probe the airbag circuit yourself; unplug airbag connectors only with the battery disconnected and the stated wait time observed
