Perfect for the Basics!
The dreaded SES light came on the other day and my gauges on my vehicle are not working so I was in need of a way to see what the issue is. I have a fancy tablet style scanner from Foxwell but for some reason it wouldn't link to the OBDII protocol of my Mercury Villager last time I tried to use it. I couldn't find it this time around so figured a cheap basic OBD2 reader will do.This reader is pretty basic but does all the functions you would expect from OBD2 standard. You aren't getting advanced features here as those are more geared to the $200+ scanners. This one on sale cost me less than $15 and as you can see from my screenshots, shown me what I need to know.The neat thing is too this scanner has a built in code library so you can manually look up a code and get a description of the issue. I've used the Bluetooth reader from this same company and it's amazing. Mine was stolen so I have to get another but I can't recommend this model KW310 enough if you just need a basic obd2 reader on the cheap!
