Sistema de retención bloqueado tras un disparo anterior

An airbag or restraints module locked out because it has recorded a deployment. This is deliberate and permanent by design: once a module has fired, it records a crash event and refuses to arm again until it has been properly serviced, so a system that has already done its job cannot be assumed ready.

On many manufacturers the module is not resettable at all and must be replaced; on others a dealer-level procedure clears it against proof the components were renewed. Codes will persist through every clear attempt, which is the behaviour to expect rather than a sign the tool is failing.

It matters most when buying a used module or a used vehicle. A module transferred from a salvage vehicle may carry a locked crash record and will never arm, and a vehicle with an unexplained restraints fault may have a history nobody disclosed. This is not an area for improvisation — bypassing or resetting a restraints fault without renewing the components leaves a system that will not protect anybody, and the deployment record is the only evidence of that. Refer it to somebody equipped to do it properly.
