Disconnect the negative battery cable and wait 2 minutes for airbag capacitor to discharge. Remove the fuse block cover under the drivers-side left footwell. On the back of the fuse block is the BCM. You'll need to remove 4 torx t20 screws (two high and two low) and disconnect two wiring connectors on the bottom back of the unit, to get it out. When all wires and screws are removed, gently rock it back and forth from the top to separate it from the fuse block. There's a connector between the fuse block and the BCM (up high) that you need to separate.
