B0060 refers to a belt tension sensor in the driver's belt, a force gauge usually bolted to the lower anchor with the webbing running through it. In Delphi's design a spring-loaded slider moves against the belt pull and a Hall element between two magnets turns the travel into a voltage; the springs give way at roughly 5 to 15 lb. CTS, which calls itself the market leader, builds such sensors in several mounting styles. A second Delphi patent has the sensor report its value in 3-lb steps over a two-wire line and flag readings outside the valid band as a high or low fault. Tension sensing serves mainly the passenger seat; a driver-side unit is rare. No carmaker documents B0060 publicly; Saab's older airbag modules do not list it. Airbag lamp on.

Likely causes

Loose or corroded connector at the anchor-mounted tension sensor
Tension sensor output stuck or out of range, e.g. jammed slider
Sensor lead pinched under the seat or at the sill trim

Symptoms

  • Airbag warning lamp on
  • Restraint module may fall back to a default firing strategy for the driver
  • Safety note: the sensor plug sits beside the seat near pretensioner and side airbag plugs; only unplug it with the battery disconnected and the wait time observed
