The Type 2 SPS (Single Point Sensing) airbag system, designed and manufactured by TRW, fitted to the new Range Rover from 1999 MY. Airbag ECUs are often referred to as DCUs (Diagnostic Control Units) because of the fact that they do very extensive diagnostic tests themselves. This means that no dynamic information is made available, neither are there any outputs which can be driven. It does however have an extensive fault memory function which can be read and cleared. A vast array of settings are also available diagnostically together with the vehicle's VIN number which can be changed at will. This airbag system has been fully developed and tested and is already available for the ROVACOM LITE system.
