B0026 is missing from the public J2012 lists. General Motors documents it in older restraint modules with a meaning other than the title: on the 2006 Saab 9-5, B0026 is an open circuit in driver frontal stage 1, set when the measured resistance stays above 4.5 ohms, tolerance 0.2, for 2 seconds; the Saab 9-3 manuals add bytes for an open loop and too high resistance in the same driver circuit. GM bulletin 08-09-41-002H blames loose connector position locks for B0026 on 2005-14 models such as the Cobalt, Pontiac G5 and GMC Envoy. An open second stage of a left side airbag is not publicly documented under this code. If the driver loop is open, the steering wheel airbag may not fire. Airbag lamp on.

Likely causes

Airbag connector or its position lock not fully seated (GM 08-09-41-002H)
Broken track in the clock spring (driver loop on older GM/Saab)
Open squib inside the airbag module

Symptoms

  • Airbag warning lamp on
  • Depending on the vehicle, the driver 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
