Hi I have read several posts about which scanners to purchase but am still puzzled. I don't want to pay the $125 diagnostic fee at the dealer but I am worried if I can see all the codes the car has. The red triangle with exclamation light flashed at me last week and then flashed at me a few days later during normal car operation at 15 mph. This is concerning and I would like to see what DTC is associated with this. Will a normal obdii CAN scanner find that code or do I need the proprietary tech to read that sort of incident? Any recommendations?
