Aston Martin used the Ford-associated Worldwide Diagnostic System (WDS). A contemporary Aston Martin DB9 OBD manual identifies its WDS diagnostic system as the principal dealer diagnostic tool for that model. Ford's 2000 announcement had listed Aston Martin among the marques planned for WDS deployment. Aston Martin DB9 OBD manual, May 2002; Ford WDS announcement.
AMDS and AMDS 2.0
According to an Aston Martin service policy letter, the Aston Martin Diagnostic System (AMDS) was launched in 2007 to supplement WDS. In 2016 the manufacturer introduced AMDS 2.0, initially specifying it for DB11 and stating that AMDS 2.0 software was not compatible with earlier models. The same letter retained AMDS for the listed earlier DB9, DBS, Rapide, Vantage and other models, using the new equipment with the earlier application. This was the manufacturer's 2016 applicability statement, not a complete current list. Aston Martin service policy SPL-00-0585, November 2016.
