The front SAM is actually the front fuse box, under the hood. The SRS module is in the center console, ahead of the gear selector. Generic OBDII scanners won't read these systems - you'll need some specialized equipment for that, and of course the dealer's SDS will do that. Since your's is a pre-MY2005, you can use Carsoft. You can usually find it for around $100.
