airbag warning light comes on when enging starts. Stays on.
airbag warning light on 2006 Mercury Grand Marquis
The light should come on when engine is started but go out when engine is started. The computer sees a problem with the SRS/air bags system, a scan tool is required to retrieve codes stored and locate the problem.
This can be dangerous and should be checked by a professional-if the air bag suddenly deployed while you were driving you would likely get into an accident.
