Can obd ii code reader/ eobd scanner updates

My reader kept showing three monitors not ready. No check engine light, but could not pass the emissions test because my vehicle was rejected. Bought OBD 2 scanner from eBay. True lifesaver. Instantly showed whta problem was on car.

So was curious and got one. On the other hand, however, if you have no mechanical e. Best of luck in your DIY endeavors! Never preferred an obd2 scanner on a laptop, but decided to give it a try.

This tool is fantastic! I used it on my car to determine the error codes for the check engine light, and was able to turn the check engine light off with this tool once I knew what was wrong. It was bigger than I expected it to be, being about the size of a computer mouse. I highly recommend car enthusiasts to own a obd2 scanner. The manual that comes with it is very informative, describing not only the codes themselves, but pending codes and monitors.

The software and ELM device will tell you about all those things, so not only will you know which codes have popped, but which might pop soon. Far more features that the more common orange-colored brand for the price. Highly recommended. I purchased the Bluetooth version and it has worked every time! Long story, short version…I have a Camaro that was due for California reg and smog in June. I went to get it smogged, via obd2 scanner at mechanic, and it failed.

Guy said drive, drive, drive. Put some miles on it brought it back and it failed again. I paid the reg fee already just needed the smog to pass. Looked on YouTube and saw a several about using this obd 2 scanner. Took the car out again today and had this plugged in the whole time. Finally after putting over miles on my car the problem light showed the ok signal. Back to the smog shop and showed the tech to check via obd2. He thought this was pretty cool. Smog done! California sucks when it comes to this stuff so now I really polluted the air.

Yes never unplug or replace the battery before smog time because it will fail. Been there and done that too. Each manufacturer has a drive routine that must be accomplished in order for all the systems to be ready for smog check. Once I learned my cars driving needs, I was able to do them in about 30 minutes and drive right back to ththe smog place and have it pass. What if your battery actually needs replacement before a smog test? Would the obd2 scanner rectify potential smog test failure with a simple reset?

So want to read your engine fault codes on your own? Can find on Amazon. It is Inexpensive and also clears codes and it reads codes. Which generally refers to you in the direction of the Gas Cap or Evap Canister on the fuel tank.

Yes, totally fine. Used Autel obd2 scanner as result of reading this article. FAct is, few models support manufacturer obd2 codes. Rest are generic obd ii pids. The light was on but no report about codes for the ABS system or the traction control. It did find an DTCs and shows Reported fixes. I was really hoping it would find the ABS. I have a Nissan Frontier model diesel motor and I am having a issue with the VP44 pump and I need clarity to fix it.

Honestly it works and it comes with lifetime updates. The lifetime updates are what really make or break these obd2 based scanners that and working on foreign vehicles. I plan to just leave it in my glove box or trunk and use as needed. I use the Dashcommand app for Android, and this works extremely well with it — quick live data refresh rate, and good access to codes and freeze frame data.

With other apps, I use it to monitor fuel economy in real time in my own vehicle. Nice job, BAFX. I wish everything worked this well for the money. My obd2 scanner, MultiDiag, is one I I think every car owner should have. It has an easy to use windows software and gives you the info you need on your car. Not only generic, but literally scans all OBD2 oem systems.

Takes about 10 minutes in total. There is no manual, but you get step by step install instructions and how to connect the main OBD2 scanner unit. I think this is a good obd2 scanner for anyone to use who is planning on buying a car from a seller. You can quickly see info about a vehicle that the owner may no know or may not want to tell you. Stumbled on this and saved me lot of time and researching finding the right obd2 scanner for our European-Cars workshop. Will give you good perspective on markets common obd2 scanners used by competitors.

Somethimes i plug the scanner and the ignition is on but the scanner say the ignition is off and i try again but this time i start engine is start what is the problem!

So I have a low pressure light on my Subaru Legacy. I plugged it in with the ignition on and tried to scan but nothing happened so I unplugged it with ignition still on.

When I tried to turn the car on it would start and then die. And even then the idling RPMs were lower than normal. Did I do something wrong? Any information would be great. Thank you. This would either need oscilloscope or car mechanic to figure out. I had the same thing happen after trying to erase code. The car will start and just die now. What did you end up figuring out was the problem?

The car diagnostics tool tool does very basic functions well, such as reading diagnostic trouble codes and checking for emissions readiness. Outside of these functions, I was unimpressed with the systems over all performance. It takes longer then you would expect to enter into the ECU. However outside of this for someone just looking for an affordable obd auto doctor for basic diagnostic ability on their car, this obd system was decent.

Same here. I was able to read codes, and reset them, from many of the components on the car, not just the engine. Problem is they all have positive reviews. I consulted mechanic. And he recommended me tech-ii on ebay. Purpose of this review is to notify readers to do your research. Do your own research please! One of the obd2 tools showed me the code, which I was then able to search online, and quickly fix the problem. Even if I take it to local garage mechanic, going into it with codes means I have some knowledge of the problem and the potential expense involved.

So my conclusion of using obd2 tool is: Proactive troubleshooting can save considerable money in long term. They showed you the fault code sure. And you have resetted it, definitely. But has the mechanical issue actually been replaced, or component fixed? Read most obd2 scanners do not support GM or Dodge? I may have read things wrong but not sure thats why I am asking.

I was looking at scan tools but thought doing pc obd2 package would be cheaper and have more benefits also to do different tests with. If any windows based obd2 program supports, I would like to know what all i need to order to do so. I would like to talk over the phone as there a lot more information that can be translated useful.

Thank You for your time. I used a obd2 scanner to get my 13 Mercedes-Benz SL to pass inspection. In addition to displaying current fault codes, the ThinkOBD shows live car data, like spark advance and engine speed, but it spreads the data over 38 pages.

Unfortunately, I had to manually type the code into the Lookup section to find its meaning. The device offered no explanation or repair options, making it second best to more advanced and expensive handheld scanners, like the Innova CarScan Pro Its ribbed sides make it a snap to pull out.

The 1. It has a single LED but it was always red. The Jethax scanner uses Bluetooth 4. In addition to a series of automotive gauges and fault codes, the system can run acceleration tests. The Jethax has a foot Bluetooth range, which was on a par with other Bluetooth scanners.

It found my introduced fault and turned off the check engine light. Big and bulky, the ArtiLink weighs The scanner can be updated using its included USB cable. The 8-key interface is efficient and lets you pick from the major categories. After I introduced a problem with my Audi AllRoad, the scanner showed the fault and zeroed in on the problem. I was able to turn off the check engine light but the scanner stopped short of providing repair advice that the CarScan Pro does.

The first time you use it, figure on spending 20 minutes before you get any automotive data. It quickly found my introduced fault and allowed me to turn off the Check Engine light.

It has a lifetime warranty that includes endless firmware updates. This scanner has a color screen and a fairly intuitive interface, but it doesn't graph data and can't turn off the oil-change light.

Nor can it suggest repairs or replacement parts. The EDiag YA's inch cable isn't enough to reach the engine bay. If you want to get under the hood while the scanner is plugged in, you'll need an extension cable. Nonetheless, this is a great way to get started with using OBD-II devices, and you'll get a lot of bang for the buck with this cheap but reliable scanner. Read our full EDiag YA review.

On the downside, at Unfortunately, it took upwards of 15 seconds for the scanner to respond at times. The Nexpeak NX may be big and heavy, but it goes beyond the expected car checks with a long 5-foot OBD cable and lifetime software updates. With soft rubber bumpers, the NX is ruggedly built and comfortable to use. In addition to examinations of the battery and oxygen sensor, the NX interprets generic and many manufacturer-specific fault codes.

The device quickly noticed the introduced fault on my car and turned off the car's check engine light. The tool's eight-key navigation makes it easy to move between scanning tasks.

If you're looking for insights into how your vehicle is working or what's wrong under the hood, there's no better way than to plug in one of the best OBD-II scanners and read the results.

After all, it's how your car dealer or repair shop would figure out what's wrong with your car when you drive or are towed in. Why shouldn't you have the same information? The best OBD-II scanners provide the right mix of size, weight and the ability to read your car's fault codes and live data. The most important criteria are:. There's a gas tank full of criteria used to determine which OBD scanner is the best one for you.

The most important is whether you want one that connects with your phone or tablet's screen over Bluetooth or a handheld unit with its own display and cable. Next, think about longevity and get one that includes lifetime warranty or software updates so the scanner will stay current with changing automotive tech. Then, how about screen size for a handheld scanner?

Get the biggest, brightest and easiest display to read that is icon based for easy changes. If you're clumsy, look at rugged scanners with rubber bumpers to absorb the shock of being dropped. Look for extras that are included on some models, like an electrical multimeter, the ability to read a manufacturer's proprietary codes or export documents as Acrobat PDF files. That's barely an hour's labor for a qualified mechanic, making it a win-win purchase.

To test the best OBD2 scanners, I used my Audi A4 Allroad vehicle while it was in the garage or on the road over a period of several weeks.

Next, I measured the cord's length on the handheld scanners and the wireless range on the others. With the car running, I monitored the engine and other vital systems, and then disconnected the engine's oil temperature sensor. Finally, I checked the details provided by the scanner, fixed the problem, turned off the check engine light and erased the error code.

Then I hit the road to see if the scanner could display operating data such as engine speed, timing and coolant temperature. I paid attention to whether the device reported the data as numbers, graphs or auto-style gauges. All fault codes have four numbers and a letter prefix:. Of the roughly 5, diagnostic fault codes available, some are generic and apply to all cars, like air temperature and throttle position. For these, the numeric section starts with a 0.

Others are specific to individual carmakers and represent either a special piece of hardware or a more in-depth analysis of the problem. These start with a 1. For instance, if you get a P code, chances are there's something wrong with the engine's intake air temperature sensor. By contrast, a Ford that displays a P specialty fault code means that the intake air temperature sensor is reporting values intermittently and should be replaced.
