I get a response with this. The % goes up on take off and turns but then goes back to 0% when cruising.wasinger3000 said:Anything look wrong with this? For some reason this is the only one that just will not work.

I do. What should I look for specifically?ecoboostsho said:

Well it depends on how comfortable you are trying this. At some point I can hopefully find time to create some screen shots of the whole process. If you are willing to you can download a free serial port sniffer - I used this one. http://freeserialanalyzer.com/wasinger3000 said:
It has some limitations (30 minute max session time) but works really well and even sees Bluetooth COM port data. You basically install that on the same laptop as you have your Scanning Software (Forscan works great). You start Forscan and connect it to the car. Then select the AWD PID you are after (and just that PID). Now before you hit the "start" button in Forscan you want to fire up the serial analyzer and then "connect" to the COM port that Forscan is using (this will vary). Select "Packet View" and then "start" capturing data. Switch back to Forscan and then start capturing the PID. You literally need a couple of seconds of data as it will create a lot of lines in the serial analyzer very quickly.
Now comes the fun part. Using the serial analyzer you can look at the data captured line by line. You should see alternating Reads and Writes. When the scantool is requesting a PID it will always start with "22xxxx" where the xxxx is the actual PID for whatever you were scanning. The response will always be "62xxxx" which will include the same PID. The next several bytes include the response from the car and they are always in Hexidecimal. For the AWD PID you would expect a Zero response and you should see a "00" come back.
For the AWD PID you also need to determine the module address. If you go back to the very beginning of the lines in the serial analyzer you will see a set of ASCII codes it sends to the car to set up the PIDs it is requesting. You are looking for a line right a the beginning that includes the following:
STCAFCP761, 726. In this example the 761 is the module address of the AWD unit in a 2011 Taurus. 726 is the address of the scantool I believe. If you find this command look for the 3 digits right after the STCAFCP... That should be the module address you are after. You take this and plug that 3 digit number in to the "Header" portion of Torque. Add your PID and equation and you should be good to go.
I know that is a lot of info to digest but it isn't as complicated as it sounds once you get in to it. The hard part is actually figuring out the equation but I think we've got that already for the AWD PID and I don't see why that would have changed in the 2013+ cars.
Good luck if you try this! I will help how I can
Honestly even if you can capture the data stream from the serial analyzer I will decode it for you. You can export it to a file from the menu. PM me and I will set you up with my personal email to look at it.

I'll try to tackle this tonight. It doesn't sound to bad. I've done worse hah. It will be interesting to see why my current pid won't work.
Thanks for the detailed how to. I appreciate it!

What should I look for when looking for a PTU signal of some kind?

Look at Forscan. Do you have a AWD module? If so check there. If not you will have to try and find it by looking at all the PID s.

Ok I have FORScan up and running. Anyone around to help? I found some cool stuff I d like to watch. Like cylinder acceleration value of each cylinder.

Interesting how it has airflow trim measurements for both a/c on and a/c off.

Combustion performance counter? I'll have to check that one out. If you have the MX adapter. You can also do the self checks for each module and perform the adaptions reset. (Kinda like unplugging the battery). Just ensure that you follow the instructions on the screen when doing the maintenance operations.

Can't find anything related to the AWD system. Its under the PCM correct?

Can't find anything! So weird. There are hundreds of them but nothing drive related. If someone gets a chance could you get a picture of the actual PID name.

This is all i have... Wonder if its just not there or if its cause im using a non MX obd. I dont think its adapter related if i am able to see so many others.
What is the PID for the AWD %?
Anyone else with a non PP 13 have any transfercase PID's?

Damn... Knew i should of got the PP.... hah.
Thanks for the late night help!
