B1706 code in owner complaints

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 B1706: 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 706 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.

Red âairbagâ light on dash illuminated while driving. Code read as B1706: passenger buckle pretensioner. May have been covered under Hyundaiâs 15yr/250k warranty but owners never notified since not official recall.

Driving on an interstate the "air bag" light came on. Eventually diagnosed srs code B1706 "passenger buckle pretensioner resistance too high" advised air bag may not deploy properly or at all until repaired. On vacation at the time, not close to a dealer. Passenger seat belt system will have to be replaced.
