This is for the small green programmable, stand alone alarm module fitted to Discoveries and Defenders and is denoted by the vehicle having two buttons on its key fob or PLIP. Manufactured by Lucas, its correctly designated name is the 10AS. It does not really have the same kind of fault code memory as other systems but does store a list of the last 5 events which caused the alarm to trigger, allowing faults which cause false alarms to be more easily traced. It gives a huge range of dynamic information values and an even bigger range of configurable settings which alter just about every imaginable aspect of the immobilisation, alarm, and central door locking functionality. A vast assortment of codes for the immobilisation links with differing engine management ECUs, key fobs (plips) and other usages is also available as well as a range of drivable outputs and internal functions such as allowing new PLIPS to be registered to the alarm system (learn mode), and learning codes from engine ECUs for immobilisation requirements. This will cover all 10AS ECUs excluding MY 2013 onwards Defenders, from VIN: EA000001
