There is little data for this code or its meaning is ambiguous, so this page is not indexed.

What the code means

This is a manufacturer-specific code: the meaning depends on the make and sometimes on the year.

How to read B1764: the letter B means body (including airbags and belts); the second digit 1 marks a manufacturer code whose meaning is set by the make; the last three characters 764 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.

Drops Codes B149000 and B1764 - this causes our air bag light to come on. This flipped on around 70k miles but because we are the second owner, we have to foot the bill out of pocket. Its asinine to think that we have to replace the entire seat and that Hyundai doesnt see this as a problem for them.

This airbag issue occurs when I am driving, parked, with someone/something on the passenger seat, and without. The codes stored were the following: B1764, B1767, B1493, B1603, B1490.

I got the code pulled at a local shop for free thankfully. The code was B1764 ocs mat defect. Now because it failed for no reason I have no airbags at all. From other people's complaints it can cost $1,000 to $3,000 to fix. Awesome. I really loved my sorrento too.
