Engine code scanner

Hello everyone,

I am wondering is there a good 9 pin scanner that can read the engine fault codes accurately? Can i use 9 pin to OBD-II wire and then use the OBD-II scanner to read it? I searched on amazon, it seems that the professional ones are very expensive, over 2000 dollars. I am not sure if the more affordable ones which are under 200 dollars are good enough. We have a 2012 freightliner Cascadia with dd15 engine and eaton fuller 13 speed automatic transmission. Thank you!

 

That's like for the shop, over 6000 dollars

 

I was looking at that one too, but i saw it has odd-II port, so your Volvo has OBD-II as well? Do you know if i buy a 9 pin to OBD-II wire and be able to make it work? Our truck only has the 9 pin port.

 

Thank you for the information, I will look into that.
