GT1 main unit problems

[cbp]

hello Dk members:
I need some help here..I have a chinese clone GT1 head that present the following issues:
a) power light is on
b) network config is ok and is comunicating with the head unit
c) once the routine of diagnostics starts recognizing the modules installed in the vehicle it frozes when it reaches the ABS system ( tested on a 1993 bmw e36 with the M42 engine)
The problem is present on 20 pin and 16 pin diagnostic connector cars..so all vehicles have the same situation
It freezes up when the diagnotics reach the ABS module.
I tried another head with the same PC and cables and worked fine, therefore the problem is in the head.
I opened the GT1 box and there is no signs of burn components, and also checked fuse F1, F2 and F3 as previously posted on another DK forum.
I dont have a good electrical diagram, just one that a DK member posted in anotjher forum, it would be great to have a better one.
So if any of you BMW gurus can give any advice would be very welcome.
Cheers and thanks in advance.

use BMW GT1 do your another system, have a look is this can do your car, if no you can try another newer cars, i think BMW GT1 can't do your 1993 bmw e36.
