The 4WAS air suspension control module is used for the RAS system. The internal processor recognizes external circuitry to determine if
it is installed in a 4x4 or 4x2 vehicle.
-
The air suspension control module is calibrated with information from the ride height sensor. A new or exchanged air suspension control
module requires that the ride height adjustment calibration process be performed. See: Steering and Suspension/Suspension/Suspension
