Instructions for Seat Occupancy Simulator 2

IMPORTANT: The Simulator should not be used when a child seat is fitted to the front passenger seat.

  1. Before installation, you will have to open the Simulator box and turn over the circuit board:


  2. Modify the 2 switches on the circuit board as shown below, or the airbag light will stay on:




    For Older BMW cars before 2007, usually set 1 ON and 2 OFF ---------->







    For newer BMW cars 2007 and after, set 1 ON and 2 ON ---------------->



    NOTE: When resetting the airbag light, if option 1 ON and 2 OFF doesn’t work,
    try 1 ON and 2 ON and vice versa, as some BMW variants generate different signals.


  3. Before continuing, make sure the ignition is turned off!

  4. From the rear, under the passenger seat, locate the wire that comes from inside the seat and has a connector with 3 thinner wires, it may also be hidden under the flap.
    (White = Signal, Red = Battery, Brown = Ground).

    Note: for some models of BMW, the male and female connectors can be hidden inside the seat, pull the wire down slowly and you should find it.

  5. Disconnect the old connector and connect your Seat Occupancy Simulator 2. Secure the device to the underneath of the seat using the cable tie provided.

  6. Switch the ignition on. If the airbag light is still on, bring your car to the nearest garage to reset the ECU and clear the airbag warning light error. Most garages are happy to do this for free as it is a very simple procedure.

    REMINDER:
    When resetting the airbag light, if option 1 ON and 2 OFF doesn’t work, try 1 ON and 2 ON and vice versa, as some BMW variants generate different signals.

Seatbelt Warning Sound Workaround

Use the black & red 2 wire Seatbelt Simulator included. After installing the Simulator 2, the seatbelt warning light will glow or the sound will start ringing as the car’s computer will now recognise that a passenger is in the seat, even if the seat isn’t occupied. Find the main seat plug under the passenger seat and unplug it. Find the black and red wires coming from the seatbelt buckle, cut these wires and connect the black & red 2 wire Seatbelt Simulator included to the plug accordingly. Reconnect everything back to it’s original position and the seatbelt chime should now stop.
