I have been at this for one week in my spare time. I have constructed the cable and I am certain it is built correct. I tested for continuity and i get tones back so no issue there. I have an $18.00 USB serial adapter I purchased from Frys Electronics. When I connect it all up and hit initialize, I am getting FF on the TX side and 28 80 on the RX side.

I know how to set my comm ports so there is no issue there. I am using comm port 1 set at 8 none 1 with a baud rate of 600. I checked device manager and the port is working. I have tried to fiddle with the delay times and still 28 80. I am thinking about getting an older PC running windows XP with a serial port to see if that may help. I just don't get why it is not working. Really frustrated at this point and any help will be greatly appreciated. I took the next 2 days off from work in hopes of getting my truck out of EAS Fult mode.

Thanks

Hey mate, I had the same problem.
So, instead of plugging into the OBD on the outside, I literally skimmed each cable at the back - ir left cable intact but took the protective cover off it with a very sharp stanley knife, and connected the wiring directly to those - I just didnt think that the connector was carrying anything through the black plug, so yeah, bypass the plug. Have since left the entire cable rolled up, and in the glove box, still connected - mines a right hand drive, here in NZ.

I then got hold a mates PC with a standard RS232 serial port, as I too had issues with the USB-serial converter, despite loading correct drivers and everything.

Once I did that, bingo!, everything worked perfect, when I clicked initialise, all the codes came back, the RX side was, 54,54,54,54 then a whole run of FF's.
I then hit UnlockEAS, ie, while the FF's were still being returned, then hit stop. Turned off the car - two clicks back - then unpluigged the serial cable. Turned the car key 2 clicks, and bada bing, all good, EAS fault gone, could hear the compressor working away, sweet as man.
