If you do what I do, you like it when the networks you are working with are terminated to a standard connector.  The OBDII connector typically contains all of the vehicle’s networks so that engineers working on the vehicle can easily access the data.  Of course after it is released, the networks are still there, […]

Not quite sure what is wrong with me, but I decided to turn on comments as a trial. I’d like to see what your thoughts are of the horrible manure in which I write my blog; how bad my spelling/grammar can be; and how absolutely incompetent I am. Please keep the language to a minimum

Because diagnostic data is built on top of a standard Transport Protocol (ISO 15765-2), you can use this knowledge to see which diagnostic service a particular vehicle supports and which parameters or sub-functions it may support. Step 1. Finding Nodes’ Diagnostic IDs.We must first have all of the nodes enumerated with Physical IDs and their

So this blog can get a bit technical, so I apologize but I assure you this is some really fun stuff. CAN BUS is intended for short, quick data transfer between controllers.  This is achieved by setting a limit of 8 Bytes maximum for any Frame that is sent on the bus.  Because of this

On most late-model cars, there are hundreds of messages with thousands of parameters being transferred between controllers, this leads to the idea that EVERYTHING is being able to be controlled by CAN BUS messages.  This simply is not the case.  If a controller doesn’t need to send internal data to another controller then it won’t. 

For those of you who like to leave there car keys in the ignition while the driver door is open or who don’t where a seat belt, you’ve heard the Chime and have probably cursed it many, many times.  Well I can help you defeat it or embrace it. First you need to gear up. 

Good news you can. Well sort of.  The VIN stored in controllers is writable (well maybe).  But in some cases its difficult and some impossible.  So I am hear to give you some tips to make life a little easier. First find out if the controller stores the VIN.  This can usually be done on

So you found a CAN BUS to reverse engineer, but you don’t know it’s buad rate.  There are a couple to find it out. One. Go one-by-one through a possible list.  CAN BUS baud rates tend to be of only certain baud rates.  I am not positive, but this most likely has to do with

So you want to get data from the vehicle?  Good news, its there you just have to know how get it. You have a couple of options: Buy the data or Reverse the Data from an Existing Scantool. So you want to buy the data, here’s how that works.  You have to be a member
