The handheld tester can be connected to your PC to get access to the huge online database that will not only help you diagnose the problem but will also give you an idea of the repair costs involved.

For starters you need to find your CarMD connection; a 16 pin Data Link Connector, which is usually under the dashboard on the driver’s side. Insert the tester into its place and turn the ignition on within 10 seconds otherwise you will get an error message. Once connected the tester will link to your car’s computer and beep 4 times to let you know that the data has been retrieved. Indicator lights will come on and if it’s green, your car is in good condition but if it’s yellow or red, it’s an indication that some repairs might be needed.

What do I get?

  • Access to database that provides accurate, tried and tested solutions.
  • Professional and excellent technical support.
  • The option to register up to 3 vehicles for every device and get up to 6 monthly diagnostic reports.

CarMD Cons:
In case of oxygen sensors even if the wire is severed you can get a voltage reading, which might mean nothing to you unless you are trained. It’s the same case for some other checks as well and thus you can still be taken for a ride by a dishonest mechanic. The Check Engine light cannot be reset and although you can add up to three cars per device you cannot delete one of them and replace it with another. What happens when you sell your car and get another one? Only six monthly scans is also a letdown.

The unit is not set up to find problems with brakes and even if you notice problems with the engine the device doesn’t always show them. The software that gives you access to the database can be quirky and getting an error page after getting a reading is extremely frustrating. Often the code you see is not recognized by the website, which makes matters worse. And the customer support is not really helpful either.

The features offered are quite limited for the price and one needs to get an upgraded subscription for many services. If you own an android phone you can get apps for as little as $4.81, which do the job as well. You can also monitor your car in real time with the help of a Bluetooth converter that can be bought for less than $20 on eBay. You can get information about code checks and recalls online or with the help of trusted local mechanics for free. CarMD is overpriced and aimed at people who trust a product easily without verifying its credentials.

The Performance Monitor also lets you measure quarter mile times and speed, your vehicle’s 0-60 time, braking performance of your drive and monitor specific gauges as well.

Cons/Disadvantages of ScanGauge II
If you try to squeeze out everything of a full tank, as many of us do, ScanGauge II is hardly of any use. MPG can be calculated yourself anyways and you can also get code readings from auto parts stores for free. ScanGauge II has also been known to drain your car’s battery, which is annoying. The results that you get keep fluctuating quite often and aren’t always accurate, which makes it a pointless exercise. Most of the information you get on these gauges only duplicates the data you get from your vehicle.

ScanGauge II doesn’t directly communicate with your car’s computer and you have to feed in all the information manually, from the size of your tank to gallons of fuel filled. And the novelty of getting your MPG readings, RPMs and other readouts wears out after a very short time. It doesn’t detect all the trouble codes either, which makes you wonder about its usefulness. HP tuner on the other hand is a safer bet and a smarter option.
