B009F would be the sixth and last right-hand restraints sensor in the J2012 block. No carmaker documents it publicly with this meaning. The number does appear at GM, but for another part: on 2008–2013 two-mode hybrid Tahoe, Yukon, Escalade, Silverado and Sierra trucks, bulletin PIT4614C ties a no-crank condition with B009F stored in the SDGM gateway to water passing the seal of the HVCID crash sensor for the high-voltage circuit, mounted on the lower radiator support; the sensor and terminals are inspected and replaced. That is a crash switch for isolating the hybrid battery, not an airbag satellite. A genuine sixth right satellite would be an acceleration unit, for example a PSI5-linked Bosch SMA773 sensor on a rear pillar or sill. Its failure lights the airbag lamp.

Likely causes

Damaged rear body harness or plug to the sixth right sensor
Internal fault of the sixth right acceleration satellite
On GM two-mode hybrids, water or corrosion at the high-voltage impact detection sensor (different meaning, PIT4614C)

Symptoms

  • Airbag warning lamp on
  • On GM two-mode hybrids, no crank or a Service Hybrid message instead
  • Safety note: airbag and, on hybrids, high-voltage system; disconnect plugs only de-energised; after a sensor change have it checked or initialised, specialist workshop only
