K line diodes shorted to ground this its why you have good Caesar Self test but you cannot accest the cars modules,but you can see the voltage of battery

**antibisic** · 4th July, 2011, 08:45 PM

Where is located this diode please?

**diagnoza_auto2000** · 5th July, 2011, 05:47 AM

I checked before this diode off board and now too on the board:

small zener has 5 V and big zener 12V
big black 12V

this I checked on board when power is on the obd plug!

What are you think is it ok?Thank you for your help what is the next step?

As you see in the picture on both red diodes you must have 12 V when you have powered your mb unit on the car.
Make me a picture and show me where did you have 12 v and where 5 v?

This is not mine but diodes are the same

**diagnoza_auto2000** · 6th July, 2011, 06:29 AM

Btw your mux its a D4(low quality mux) and its a little more dificult to repair then a D3.
Check the picture.

**antibisic** · 6th July, 2011, 08:33 AM

Hi mates,
now is my turn ... My china's clone is something special - it has usual rs232 cable from laptop to mux (no rs232-rs485 converter), it don't support win-hht, it don't pass mux test at all - "no D part is connected" says... BUT! It works good enough with any cars with obd2 socket, with trucks and vans (14 pin and obd cables), and something strange works in e-class with 38 pin cable - it could't find some existing ECUs and found not existing... I had broken cable from laptop to mux, but recreate it as I could guess... Maybe pinout was wrong? Pictures attached:
