i have the three codes in my bcm via genysis scan tool. from the research i did its related to left front drivers side air bag sensor. does anybody have the part number for that sensor for my truck in my sig? 2005 gmc sierra. ive done searched and it just shows similar codes and problem but no part numbers to know which sensor to order.

make sense?

thanks
steve

 

BCM??? Or SDM??? Are you referring to B0100,B0101, and B0102? Those are all codes for the left front discriminating sensor 1 which is the left sensor below the radiator support. 95% sure it is a bad sensor and needs to be replaced but still could be a wiring or SDM concern. I've replaced tons of them and most of the time it is the sensor. You'll need a 10mm wrench to replace it. If the problem is fixed your Air Bag light will go out.

 

yes sir exactly what you wrote. do you know the part number for that sensor? and best place to get it from? thanks
