According to RAVE:
"The ECU is located underneath the right hand front
seat, on top of the fuel ECU. It maintains the
requested vehicle ride height by adjusting the volume
of air in each air spring. It is connected to the cable
assembly by a 35 way connector. To ensure safe
operation the ECU has extensive on board diagnostic
and safety features. The ECU is non-serviceable, in
case of failure it must be replaced."
