This is a cheap OBED electric handbrake reset tool for brake pad servicing.
It is also a OBED code reader and does this by plugging into the OBED port under the dash.
I have used it reliably for 8 years with my V70 2009 D5 to do multiple rear brake pad replacements.
I have sold the car and it DOESNT work on the P3 2016 XC70 I now have.
They seem to be getting hard to find now as the P2 is getting on a bit so thought it would be good to pass on.
