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 B101D: 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 01D 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.
