I bought an Icarsoft LR V2 scanner as I have a problem with my parking sensors and thought this may help in getting to the source.
I hooked it up on the day I received it to make sure it worked OK and all seemed fine. Then Last weekend I hooked it up to see if I could get to the root of the parking sensor problem but the machine would not come on. All I got was a blank screen and a faint high pitched noise. Also the dash lights up (this is without the key in the ignition). The Icarsoft has no independent power source so it must have been getting power to it to make the noise. I hooked up another scanner I have and this was not getting a signal. Does anyone have any ideas?
