A controller determines a load weight associated with a plurality of pneumatically independent circuits of a vehicle suspension system. The controller is adapted to receive a first electronic pressure signal, which is based on a first pneumatic signal representative of a first pneumatic pressure in a first of the plurality of pneumatically independent circuits, and receive a second electronic pressure signal, which is based on a second pneumatic signal representative of a second pneumatic pressure in a second of the plurality of pneumatically independent circuits. The controller is also adapted to determine the load weight based on the first electronic pressure signal and the second electronic pressure signal. The controller is also adapted to control an operation of a function of an associated vehicle based on the load weight.
