SupporterHave a EAS Fault today.
Down on the bump stops and arranged a tow home.
Hooked up the EAS software but am having problems getting it to read and rectify fault.
Am using a USB to serial to plug to the OBD to car and irrespective of what port we elect for the USB on the computer the software will only communicate on comm3, unfortunately comm 3 is inuse on the computer and cant use it for the USB selection.
When we follow U tube steps the TX and RX readings are the same and are usually a sequential number with either a 1 or FF following eg 25 FF, 26 1, 27 FF, 28 1, etc.
These numbers just keep going and not sure if they are suppose to stop or continue as they may just indicate the communication betwwen the software and the car.
Whilst this is running we can list a heap of faults and can clear them from the screen but this has no effect on the car EAS fault, Also have sequential numbers in the boxes being 248, 249, 250 etc.
Not sure if I have a dud connection or what. Any help or explaination appreciated.

What version of windows are you running on the laptop ?
If its windows 7, it can be tricky to get the USB cable working properly if it's 64 bit.
Otherwise you can go into device manager -> advanced and set a new port for the USB cable, one you know you can use in the eas software.

Ok, have you tried manually changing the comm port ?
From memory the unlock software lets you pick from 1 to 12. You have to get the USB cable on one of those ports for it to work.

Sorry I re read that you have changed the comm port.
I have not seen the eas software default to only one port. When I use it I can select any from 1 to 12.

Supporterthats the bizarre thing about it. If on the laptop you select the comm port say comm 2 and then go into EAS and select comm 2 it will TX but will not RX. If without changes the comm port selection on the computer but just change the selction on the EAS for comm 3 and run the software it will initialise and TX and RX problem then is every second number in the RX will have a number 1 after it rather than the FF (EAS says that all readings in the RX should be FF and not numbers. Cant see why it is communicating on a Port that the USB isnt located on
Wizard
No it is not communicating properly.
I have one or two different versions of the eas tool, have you tried any other ones ?.
Also try rebooting laptop with cable plugged in, you need to persevere to get the comm ports matching.

Supporterno only the version i downloaded today.

I have had a closer look, and your description of the Tx and Rx sounds right actually. See the attached screen shot I took from a session.
This is what it looks like in proper communications, it keeps scrolling through and adding a line about every second.
As long as the Rx continues to respond with the FF, then it should be OK.
As they say, if the RX side starts showing numbers or only shows numbers where you see the FF then it is not communicating properly.

AT REST
The USB connection could be at fault. I had to change my cable before it would work. Without going out to the car, the cable form the OBDII comes out to a plug which then is plugged into the USB adapter which is then connected to the usb on the computer. Very cumbersome, the cable relay needs to just terminate in the USB connection.
