The 10AS uses a now obsolete Motorola processor, to provide modules for Defender production Land Rover had the module redesigned around a modern processor but retained the same connectors and pinouts. This module was introduced in 2012 and has proven to be troublesome with a distinct lack of support by aftermarket diagnostic tool manufacturers.
This module is easily distinguished as it uses a black plastic case and 10AS is not printed on the white label.
The label will show a part number such as
CH12-15K600-BC or similar.
