What the code means

Second Row Center Seat Belt Pretensioner Deployment Control. Generic meaning per SAE J2012 (the same for all makes).

How to read B0074: the letter B means body (including airbags and belts); the second digit 0 marks a generic SAE code shared by all makes; the last three characters 074 identify the specific fault.

Restraint system codes: airbag squibs, belt pretensioners, crash sensors and occupant classification. After a crash with airbag deployment, many makers require the restraint module to be replaced or reset by procedure because it stores crash data. An airbag light on an auction car is not cosmetic: airbags, the module and sensors can cost more than the body repair.

What to do if an auction car has this code

Ask for a dash photo at start-up: the airbag light must go off after the self-test.
Check the interior photos for deployed airbags and fired belt pretensioners: replacing the restraint module, airbags and sensors is a large separate part of the estimate.
Budget a scan with a restraint module read-out: the code alone does not say which part failed.

What owners report

Excerpts of owner complaints in the original wording. Owner statements not verified by the regulator; personal data removed.

My airbag light comes on intermittently and will show a passenger is not in my front seat when they are. I took my car to the dealer and they got a current and past code B0074 for the passenger presence module. There was a recall (18208) for this on certain 2016 Malibus but my vin was not included.
Chevrolet Malibu 2016 · 2024-07
Fault cleared when vehicle is turned off/on. Dealer (paradise chevrolet, ventura, ca) advised that passenger presence and airbag systems have an 'internal fault' (B0074, B0081) which dealer service rep stated may cause the passenger airbag not to deploy correctly in the event of an accident.
