Got in the car this last time and the red dummy light for "air bag" came on - is this common? it is a 2002 Bonneville SSEi - has 82,000 miles on it.

Wonder if a OBD scanner would tell me more

Any help is appreciated.

A budy of mine works the code reader at a shop - slipped in there after hours and it gives a body code of B0100 - he printed off the Alldata description of the error.

But can't find the EFS (Electronic Frontal Sensor) to by - or even where to find it on the car.

Found it on the car - mounted just aft the radiator on the radiator support - however - anyone know where to buy the silly little sensor?

Inflatable Restraint Front End Discrimating Sensor (EFS-Electronic Frontal Sensor) - Found some online for some cadillacs and some othercars- for around $30 - but can't find squat for my Bonneville.

Anyone?

Found it: PN 25725855
