DAF Air Suspension Control Fault Codes List
DAF Air Suspension Control Fault Codes also called ECAS. This code provides service and fixing information for the DAF electronically controlled air suspension. It ensures that the axle road ratio is correct as the sensors measure the actual pressure per axle. Once it is necessary, the air pressure is adjusted accordingly to the situation.
