Vehicle 1: 2001 Ford Ranger 3.0l, full OBD2 compliance
Vehicle 2: 2012 Mazda 5, full OBD2 compliance
The Android: Nexus 7
The Adapter: cheap ebay ELM327
The Build: Torque Pro 1.6.62

Ok, ok, I get it. I knew going in that the knockoff ELM327 was problematic.

In the Mazda, this setup works brilliantly and does everything that I’ve asked it to thus far.

In the Ford, its an utter failure. Torque can connect to the adapter, but not the ECU.

When I first got the adapter, there was a blown-fuse issue that cut power to the OBD2 plug entirely. I’ve since resolved that, and all signs point to the vehicle side of the OBD2 interface working correctly.

Quandry #1: How can I prove that the adapter is not correctly communicating with the Ford’s ECU? I assume that this is a matter of pulling connection/protocol logs, but I’ve not yet learned how to do so.

I basically accept that purchase of a new adapter will be necessary. That’s ok by me, as I can just keep the current knockoff permanently in the Mazda where it works so well. For the Ford, I desperately want Torque to work properly, but I don’t want to throw good money after bad, spending time/money trying different and possibly unproven adapters. That leads me to …

Quandry #2: Are there any documented, proven successful installs on a Ford truck? I’m not overly keen on stepping up to the Kiwi PLX units, as they seem to have a spotty record with Ford trucks. Nor am I keen to go with one of the 0~0 units for simple reasons of cost. Has anyone had success using the Scantool.net OBDLink cable in a Ford J1850PWM installation? While the idea of a Bluetooth adapter is nice, I’d gladly sacrifice some form-factor and convenience for a rock-solid stable adapter link; that it is nearly 0 is just icing on the cake.

Thanks!

I have purchased (4) BAFX BT Adapters from Amazon (BAFX Products)
which have worked successfully on Fords (2004 Crown Vic and
2000 Focus which use J1850PWM) so far.

Capp777– Thanks so much for the recommendation on the BAFX. Plugged it in last night and it works perfectly!
