B0041Third Row Left Frontal Stage 1 Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- B0041 would report the first stage of a frontal airbag for the left third-row seat, which would have to deploy from the back of the second-row seat in front of it. Such bags are described in patents, for instance a Daimler application for an airbag at the rear of a front seat and a Mercedes-Benz filing that compensates for a sliding seat with stacked chambers, but no production vehicle with third-row frontal airbags is known; the S-Class rear airbag serves the second row only. No maker documents B0041. GM's old numbering is unrelated: for the Saab 9-5 of 2006 B0041 means an open driver side airbag loop, read as more than 4.5 ohms over 2 seconds. Airbag lamp on.
