Question: Does This work on a Mediun duty truck?
Document: Two stars until we can figure out what went wrong with our diagnostic tool. I purchased this product as part of a buzz campaign. It was an early father's day gift for my father. The system worked as indicated for about three days and now, will not work properly when connected to our computer. When my dad hooked it up to his truck, it gave us a code that we looked up using the included software.
The website/software is very informational, but I wish that it would also show part numbers of the items I need to replace on my truck or even links for showing me how to fix it myself. I found 4 possible fixes with 1 being the most likely cause and the 3 other as being other possible fixes, but I am hesistant to buy the costly parts myself and fix it myself knowing that my first attempt at fixing it might not work.
I did all of this "testing" myself, and about the most mechanical thing I do with my truck is fill it with gas. Good purchase if your car plans on having a lot of problems in the future...
Now, we know that our truck would not pass and know what to do to fix it before we move!I'm not sure if I would ever have paid full price for this product but now that I have used it, I think it would be worth the money.
I will say that in his excitement to use the product, he may have been overzealous in checking and re-checking his truck after the part was replaced (to ensure the code wasn't still coming up). However, the problem didn't occur until we tried to use the CarMD on *my* car.
The report said truck had been sitting to long and needed to be driven.Go figure!So glad we had this .If we had gone to a repair shop they would have done something costly I'mI'm sure. We really like this CarMd. I recommend it highly...
The CarMD passed this vehicle with out any problems since no check engine light was on. After talking to my neighbor i learned his 12 year old truck had a check engine light which has been on for several years. Using the CarMD we were able to retrieve the code which translated to a faulty o2 sensor.
The CarMD is a diagnostic tool which connects to your vehicle's On Board Diagnostic Port (OBD2) and helps you understand what's going on under the hood. It has one function only, to help you understand what, if anything, is wrong with your car utilizing this device and your computer, whether Mac or PC.My husband entered the info for his truck, first and ran the diagnostics on it.
I was able to get the CarMD at a discounted cost for being a BzzAgent to review products. My truck had the check engine light on and I had previously used a friend's scanner and found two codes. I received the CarMD and found it extremely easy to use. I hooked it up to my truck and only one of the previous found codes came up.
I purchased the CarMd about a month ago....and I can't say that I am disappointed. I plugged it into my truck, and it told me two things that I already knew (from going to the garage and being charged $30 for that info) and 1 thing that I didn't know. It also explained what needed to be done to get them fixed, and the approx. cost of needed repairs.
Answer: no
