test platform


With test platform, there is no need to disassemble and install the control unit in the car back and forth, just take down the FEM module, then you can operate on the bench.





Tools read ISN code


Autel 808, CGDI and Yanhua ACDP can read ISN, but not all, B48 is okay,but some encrypted N20,B38,MSV90 can’t be read without opening, have to open and use other devices.


Autel 808 and CGDI and Yanhua ACDP is economic to read some ISN on EGS and DME like B48, those expensive licensed devices: CMDflsh、X17、Dimsport、KessV2、Ktag also read N20,N55,B48,MSV90 without opening.
