Thread: Inertia switch

I have a 2007 DiscoveryTDV6 with a Fault code B1A55-14 (AF) Crash record output circuit short to ground or open. This is supposed to be fixed by resetting the Intertia switch. I cannot for the life of me find this thing and I've taken most of the passenger side behind the glovebox apart. The wiring diagram does not show an inertia switch. Can anyone please tell me if there is one and where the hell it is exactly. If not how to I reprogram ECU.

I always wondered what that menu item was for!

There is no separate intertia switch in the D3/4. There is a separate hardwired "Inertia event" wire that runs from the airbag module to the ECM however. That makes sense as the airbag module manages all the accelerometers to detect what would be an "Inertia event" anyway. I suppose doing it hardwired takes the possibility of CAN bus damage out of the equation when forcing a shutdown.
