WARNING: This page is about a different car, the 2009 Lexus IS 350 and 2009 Lexus IS 250. However, it is still accessible from the selected car via links, so may be relevant.

The meter CPU receives satellite switch signals from the satellite switch in this circuit.
The meter CPU sends satellite switch signals to the tire pressure warning ECU, AFS ECU, clearance sonar ECU, driver side mirror ECU and passenger side mirror ECU using the BEAN lines. Each ECU controls every system based on these signals.
