Hi,
Recently my scanner Maxisys pro is not connecting to certain type of cars such as honda, range rover, cherokee...etc. The scanner shows a green check on the VCI and car logo but it is giving an error (  No communication between tester and control unit, Please check cable.../ ignition / battery/ correct vehicle ).I think it is not working with canadian and american cars. I tested it on toyota and it worked fine and then tried it with a toyota american origin didn't work. also i tried it once on a bmw it worked then tried another bmw and it didn‘t work.
I bought a new DLC cable and it gave the same problem.
I thought at first it was a problem with the scan files of the scanner but now i am sure it is a hardware problem with the vci (j2534). How can i verify that this is the problem and how can i fix it.

I contacted there support but no reply

 I am connecting the j2534 to the maxisys tablet via bluetooth and tried it via usb. they gave the same problem.

I will to connect it to the laptop directly and see what will happen.

 Hi,
i tried the vci J2534 with tha laptop and it detected it normally, i even updated it.
I think my scanner is not working with cars with origin US.
I asked support but no reply, I just want to know if the problem is with the update or with the hardware before i can take another step.

 I updated the J2534 to version 3.21, and some people are getting the no communication issue with the update, i dont know if thats the case for me.
