B0014 is not in the public J2012 code lists; there the driver knee airbag has B0004 and the passenger knee airbag B0013. The number is documented only at General Motors, and with another meaning. GM modules from about 2010 use B0014 for the side airbag in the driver seat; the Saab 9-4X 2011 manual adds a fault byte for each failure, from a shorted or open loop to a high reading (0D, over 4.2 ohms) or a low one (0E, under 1.4 ohms). GM bulletins blame chafed or loose seat harness connectors and high connector resistance on Silverado and Tahoe 2014-15, Equinox, Traverse and the Bolt EV. Older Saab 9-3 modules used B0014 for a short in the passenger frontal stage 2 loop. A knee airbag meaning for this code is not publicly documented.

Likely causes

On GM vehicles loose or high-resistance side airbag connector under or in the driver seat
Seat harness chafed by seat frame, motor or foam
Internal fault in the airbag module served by this loop

Symptoms

  • Airbag warning lamp or service airbag message, often intermittent
  • Affected airbag may not deploy
  • Safety note: do not probe the airbag circuit yourself; unplug airbag connectors only with the battery disconnected and the stated wait time observed
