Generatic OBD2 Diagnostic Scan Tool, Mini VCI J2534 Code Reader Cable for Techstream

Is a 1.4.1 firmware rather than latest 2.0.4 cable, can’t be updated. Comes with a newer version of Techstream that therefore does not allow for customisation features. For those you need to find an older version of techstream (v10.30.029). You also need to find the FTDI drivers separately and also change ports to COM5, plus other adjustments to get it to work, without any provided instructions (but you can work out from online if you have lots of time!). However, once finally working (on old techstream version) I was able to change some basic settings on a 2015 Lexus IS300h, for example increasing the volume of the turn signal switch, which is set very quiet out of the factory. This cable is cheaper than others to reflect the older firmware, but you can spend more for a 2.0.4 cable which is compatible with newer techstream versions.
