VVDI Prog failed to read BMW CAS4-1L15Y (solved)

I tried to read BMW CAS4-1L15Y ECU with original Xhorse VVDI Prog ecu programmer, but failed. Then I followed the VVDI-prog factory instruction,still failed to read it. So i contact obdii365.com engineer for help. It worked 100%.

 

Here is the final solution:

Take off the component between GND-C and CLK IC circuit. It will read.

Engineer’s suggestion:

1- check you wiring

Group 1:

GND – black line

VCC – red line

Group 2:

BKGD – purple line

RESET – yellow line

XCLKS – green line

Group 3:

GND-C – black line

CLK – gray line

Note: DON’T lengthen the CLK line and GND-C line.
