Using an OBDII code reader you can retrieve a substantial amount of data from your DB9’s Powertrain Control Modules (PCMs).   In an earlier blog post I explained how to connect an aftermarket OBDII code reader to the car.   In this post I want to detail the 45 pieces of Live Data information that will be accessible using the generic OBDII codes.

In a previous post I explained how you can hook up an aftermarket OBDII Code Reader to your DB9 to retrieve Diagnostic information from the Power Train Control Modules (PCMs). What’s disappointing is that Aston Martin has kept much of their code system proprietary (accessible only via the Dealers more advanced AMDS system) and thus we can only get rudimentary information using the generic industry standard OBDII codes (check out my post on the 45 pieces of data available using this method) .

On a lark I thought “Since Aston Martin was owned by Ford when the DB9 was initially designed and built, maybe the PCM’s are really programmed with Ford codes”.   There was some clue to this as well on the Aston Martin Technical Information website – in the early years of the DB9 the Dealers used the WDS system to access the PCMs (the predecessor to the current AMDS), which I discovered is Fords Worldwide Dealer System.  If the WDS is designed to talk to all the Ford models of the world would work for it, maybe this would work for me too.

In previous posts I’ve explained how to connect and use an aftermarket OBDII code reader to talk to your DB9’s Powertrain Control Module (PCM), and how you can use a trick to tell your Code Reader to talk to the PCM as if it was a Ford 3.0L V6 to get vastly more live data than with the generic OBDII code scan.

In this post I wanted to list the 200+ items that would be available to you if you follow this method (and so the Google search engines might index them and lead people back to this how to).  Maybe if you see what you are needing below, it will give you the confidence to move ahead and use a code reader to help you with your project.
