Some users reported that they failed to read Ford Lear MC9S12XEP768 BCM using OBDSTAR DC706 on the bench.
Problem 1:
DC706 cannot get it to communicate with the Ford Lear BCM, and neither does V2 black housing.
image attached:
Here is the clue.
DC706 does both. The old version ground pin is 1 pin across. If failed to read this module with pinout 1, try pinout 3 in DC706. Pinout 1 and Pinout 3 have only one difference- the ground PIN.
Or use I/O terminal pinouts.
One of our customers had the same thing, io terminal pinout shows gnd 1 pin across. and works without problem.

Problem 2:
FORD LEAR MC9S12XEP768 V2 I have 2 here and neither connect. Also tried thru OBD on a 3rd one, and can’t connect at all.
Solution:
Install the fuses. Won’t read without proper power supply to board (fuses).
Feedback:
Needs one fuse to work, and wasn’t in it. Just looked at second one that has full fuses, and wouldn’t you know, 10A that feeds internals was blown!! Picture fuse that needs to be in. So, lesson learned.
Problem & Solution 3:
I was trying to read a Ford BCM when I got my 706. Would not connect at all. Until I realised that I’d unsoldered the daughter board to get to a blown bulb driver
