Airbag module reset vs replacement: which do you need?

After an accident you generally have two options for a locked airbag module: reset your original unit, or fit a replacement. For most cars a reset is faster, cheaper and simpler — here's how they compare.

Resetting your original module

A reset restores the module already fitted to your car. We clear the stored crash data, return it to factory condition and bench-test it. Because it's your original unit, its coding stays intact and it refits plug-and-play. Resets start from $150 — far less than a new module — with a fast turnaround.

Replacing the module

A replacement means sourcing a new or used control module. New units are expensive and often need programming and coding to your VIN by a dealer or specialist. Used units are cheaper but risky: a second-hand airbag module can arrive carrying its own stored crash data, leaving you with the same warning light.

When a reset is the right choice

• The module is electrically sound and simply holds crash data after an accident.
• You want to keep your original coding and avoid dealer programming.
• You want the lowest cost and quickest return.

When replacement may be needed

• The module is physically damaged (water, fire, crushed housing) beyond repair.
• The circuit board has failed rather than just holding crash data.
