B0071 is one of the codes that does not mean the same thing on every vehicle. Depending on the make and year, it points to a center seat belt pretensioner, a forward sensor, or a seat presence mat.
B0071 lives in the SRS body code range, but the exact component it names changes across manufacturers. On some vehicles it reads as the first row center seat belt pretensioner deployment control. On certain GM trucks it has been tied to the passenger presence seat mat sensor, which wears out over time and is common on 2007 to 2014 models. On other platforms it shows up as a left forward discriminating sensor that the module no longer recognizes.
That spread matters because the repair is completely different for each one. A worn seat mat sensor, a forward crash sensor, and a center belt pretensioner are not interchangeable problems. The code number alone does not tell you which one you have.
[VERIFY] B0071 has multiple documented meanings across makes and years (center pretensioner, passenger presence sensor, left forward sensor). Confirm the exact definition against the factory service manual for your specific year and model before deciding on a repair.
It depends entirely on which version of B0071 your vehicle uses. If it is a center pretensioner that deployed in a collision, that is stored crash data a reset clears. If it is a worn seat mat sensor or a forward sensor fault, that is hardware and the part needs attention. The honest first step is confirming the definition for your specific make and year, then reading the code against the crash history.
Only when B0071 is stored crash data from a deployment, such as a center belt pretensioner that fired. In that case our airbag module reset clears the deployment record and returns the module to factory-ready condition. If B0071 turns out to be a seat mat sensor or forward sensor fault, the part itself is the repair, and we will tell you that straight.
The seat mat version is common on GM trucks. The center pretensioner and forward sensor versions appear across GM and other makes in the generic body code range. Knowing your exact make and year is what tells you which B0071 you are dealing with.
Confirm what B0071 means for your specific vehicle first. If a center pretensioner deployed and the module is locked, make sure the car is mechanically safe and the deployed parts have been replaced, then mail us the module. A reset clears stored data; the physical repairs are a separate step that comes first. Related codes worth checking: B0081 (center belt load limiter), B0078 (right front impact sensor), and B0083 (load limiter or impact sensor).
Mail us your original module. We restore it to factory-ready condition for a fraction of dealer cost, the same way we have since 1997.
