After receiving the reader in the mail, I opened it and looked through the booklet. Seemed pretty easy to me. So I plugged it into my car's port, turned the key to the on position without starting the engine. It brought up a code and then identified it as the intake manifold tuning valve. Went to the genuine GM parts store online and ordered the part for my 2008 GMC Acadia. Then went to youtube and watched the valve being changed. Didn't seem to difficult. Once I got the part, I removed the old valve and replaced it with the new one. Took about 20 minutes. Started the car and it ran fine. Placed the ignition in the on position without the engine running, plugged the reader back in, was able to clear the code and engine light was off. Paid $23.85 for the reader, $153 for the part. Since the part listed for $279 that is most likely what the dealer would have charged me for the part, plus, $99 diagnostic fee, plus I'm guessing $150 for labor. Saved myself roughly $350 and I have the reader to use some other time when needed. I love saving money! Thank-you.

Mr. Anderson

Worked on my '04 Tundra to read and reset a code. The local mechanic shop wanted to swap out both of my catalytic converters due to an error code being thrown by the driver side rear exhaust gas sensor. I used this reader to check the code myself, a quick Internet search showed that sometimes the code is misinterpreted as a bad cat when it's really a bad exhaust gas sensor.

I swapped the sensor myself with a $90 replacement and reset the code with this device, problem solved.

This is a great tool at an amazing price. Everyone should carry this in their glove compartment. When my check engine light came on I decided to get this gadget rather than pay the dealership $175 to check it for me. It’s easy to use gave a clear reading of the error code. I took it to a local mechanic to get fixed he got the exact same error code that I had so it definitely works. Definitely something everyone should have just in case. It will save you money in the long run!

This is an excellent OBD2 scanner for its intended purpose.

I run a small repair shop and have a drawer full of scan tools. This does not compare to my $1500+ professional grade diagnostic suite, but it is not meant to. However, this scan tool has one main advantage over all of my other tools: it connects and loads extremely fast with no other specialty items needed. This tool boots faster than I can crawl back out from under the dash of most cars and can read codes within seconds of turning on the key. Newer cars with lots of modules can take minutes to load on my professional grade scanner. When one just wants to check/clear engine codes quickly, this thing is a lifesaver.

I also have the Bluetooth scanners other brands make. Those are nice and some have a few more features, but you must have the app and go through the connection process. While that can be nice, it does not lend itself to be loaned out. With this scan tool, I can easily loan it to a buddy or potential customer, and they can scan and be on their way without wasting time downloading an app. This is also a consideration for those less tech savvy. The no questions plug and go that this provides is definitely worth the purchase price.

The only issue worth considering is the short cord. It is long enough for most vehicles, but vehicles that tuck the connector way up under the dash or in the passenger floorboard may be too short to comfortable reach from the driver’s seat. However, the short cord allows it to easily fit in a glovebox or small toolbox and not take up much space, such as where it currently lives in my work truck.

I just got this recently and it is pretty good.

It installs or should I say connects easily and detaches easily. Once plugged in, the scanner starts up and gives you 2 options: Setup and Scan. This is where the only issue I found comes in, since the buttons are labeled: ESC, UP, OK, DOWN but the screen says Enter and Exit.

You use the esc button to exit and the ok button to enter. The arrow buttons are to navigate the menus.

The setup screen only has options for language, unit of measure and screen contrast. You dont need to adjust any of them. The Scan screen is what you use to read and erase your engine codes.

If you decided to use the scanner to erase/clear your engine code, you need to turn on your engine to the accessory setting (when your radio comes on but the engine is off) and clear the code. you then need to turn your car off and on again to check if it worked.

for the price, its a pretty good device.

Kindle Customer

Previously, I went to the local auto parts store, borrowed their scanner to read my car's error code. Easy enough, but this reader for only $17 promised to do the same thing (their readers were usually $30+). I gave it a shot and am happy I did. This reader appears to have the same basic functions and was easy to use. I tested it on 3 cars (USA, Asian and Euro). None had any lights on, and the reader worked on all 3 cars and confirmed there were no active codes.

1) I wasn't able to watch the instructional video mentioned in the manual, but it's not really necessary. Nor did I contact customer support for a link. 2) It doesn't say how the reader captures the freeze frame, maybe if I had an actual code to read it would be obvious. This is a nice feature, but since the unit is powered through the OBDII connection, you can't unplug the unit take it somewhere and pull up the error code.

I gave it 5 stars based on value. It's a basic reader, it works, it's easy and if I need more advanced diagnostic functionality (as I may still want), all the others I was/am looking at are over $100. For $17, I'm happy.

This OBD II reader is unlike the inexpensive ones that you have to use an app on your phone to activate (which I also own). This is a stand alone reader that is very user friendly, and prompts you on every move. It immediately identifies your car, and you don't have to enter the year, make, engine, etc. of your car. This unit is also inexpensive compared to others on the market, and I highly recommend it.

After hitting a few bumps on the road and noticing the "Service Engine Soon" light come on in the middle of my commute, I was afraid that I would have to take a day off of work to get my car inspected and fixed. Thinking I could at least save some time and money by knowing what exactly was wrong with the car, I ordered the ANCEL AD310 Classic Enhanced Universal OBD II Scanner Car Engine Fault Code Reader CAN Diagnostic Scan Tool - Black https://www.amazon.com/dp/B01G5EA74I/ref=cm_cr_ryp_prd_ttl_sol_0.

My hope was to figure out if the problem was major enough to get it fixed by a professional, or if it was something I could fix on my own. I used the Scan Tool as soon as it arrived, and right off the bat the tool gave me the engine fault code and the description. Turned out, I had an "Evaporative Emissions Leak", which could be caused by a loose gas cap. Sure enough, my gas cap was put on wrong, and after a day the engine's computer reset and cleared the fault code!

I could have easily spent $200 just for a mechanic to tell me my gas cap was on wrong, so literally within the hour of receiving it, the Scan Tool paid for itself several times over!

I definitely recommend this product!

I recently purchased a used car. Almost like clockwork the Check Engine Soon light turned on. I don't know a lot about cars, so I didn't want to walk into a shop and get taken advantage of. I purchased this reader so that I could get the codes myself and research them on the internet and potentially estimate the cost of the repairs. I was able to confirm that the shop I went to got the same codes I did.

The reader is very easy to use. You just need to locate where the reader would plug into your car. You can choose to clear the codes after you read them which will likely turn off the Check Engine Soon light. It's not a bad ideal to run the code check again if the light comes back on to see if you get the same codes.

I highly recommend anyone to get this code reader just to keep in your tool box. It could save you hundreds of dollars in unnecessary repairs from unscrupulous car service shops.

Be warned this is not your typical code reader. This one gets into the the technical stuff. A lot I have no idea what I was looking at. I learned to use a few of the functions from uTube videos. I learned enough to find out I had a plugged EGR valve and I have to 02 sensors that are bad. I have the shop manuals for my car and the more I study this instrument the more I like it. The best feature I think is the graphing. Watching the operation of the 02 sensors on the graph mode enabled me to locate the bad sensors in a couple of minutes. If you are willing to take the time and learn how to use this scanner, you'll be glad you bought it. I'm very pleased with my purchase. However when you order this, order a case and the extention ribbon. You will want to protect this little jewel. The extention ribbon allows you to hook up to your automobile computer and be able to sit comfortably in the driver's seat while you are doing the test instead of being hunched under the steering wheel. Great scanner, great price!

I kept bogging down on my 1998 CR-V. I checked and rechecked timing, fuel pressure, spark plugs, distributor, everything. NO check engine light on, I was going crazy. Finally decided to shell out the money for a "pro" scanner, better than my $20 walmart one. I plugged this one in, took it for a test drive with the data record feature, and guess what I found- a bad O2 upstream sensor. It kept telling my computer it was rich (voltage was .6 to 1.2 all through the ride), and the downstream sensor dipped to near 0 as the computer cut back fuel. My short term fuel trims went down to -30%. All of this and NEVER threw a darn code for me to figure it out. I spent hours upon hours trying to find the mechanical issue, when this electronic tool took care of it in about 15 minutes. A no brainer, your time is worth way more than this costs, buy it. And I'm your average tree shade mechanic who works on his own cars, not a fake reviewer as you can see on my history. This product was that good for me to leave a glowing review

CouchTater

This analyzer totally performed to my expectations. Very simple and intuitive with minimal need for referencing the instruction book (which is pretty thorough).
It accurately diagnosed the cause of my Check Engine Light (error code P0013). Went on YouTube to learn how the replace faulty VVT exhaust solenoid, and after a trip to Autozone for the new part, was able to replace it in about 20 minutes. Rechecked system and it was good to go. Loved that I was able to clear error code from car's ECM memory after the repair. Now I can pass the annual emissions test that is required to renew my next registration here in Texas.
Chevy dealer wanted $125 just to connect to the OBD2... then would add parts/labor to that.
Paid $65 for the scanner tool, $48 for the part and came out way ahead, plus I now have a scanner to use for any future CEL.

Overall this OBDII Code Scanner delivers on all the basics and then some. It was able to quickly connect to my car. It clearly showed fault codes and clearing them was intuitive. I have a few other OBDII scanners/code readers (see photo) and this one pulls the same data (and more in some cases) as the others for OBDII data. On top of being able to read codes and clear them. You can use this to actually troubleshoot using the live data streams of the O2 sensors, A/F sensors, Long-term and Short-term fuel trims, as well as ~40 other live data pids. You also can view the Mode6 data. My older units will not pull Mode6 data and do not have air fuel sensor pids so it is showing as O2 pids even on newer cars with A/F sensors. All in all it does the job and for a $25ish code scanner this is a great bang for the buck. Side note, the cord measured 34" and was plenty long for me to use sitting in my front seat holding the unit.

A couple things you should know that some may consider cons (but again it is a $25 tool)
1. You can not select a set of pids when viewing live data you scroll up and down to see the pids you want
2. There is no graphing of the streams
3. There are a lot of abbreviations so you may need to look up some to know what your viewing
4. Screen is on the small side (but that is also what makes it compact and convenient to store in a glove box)

So even with the "Cons" for the price I feel you are getting a great tool that does the job it is meant to do so for me it is 5 stars.

Richard McCauley

Out of the box this scanner is easy to use with a MUCH longer cord than some of the other pocket scanners I have owned. I bought this particular scanner because my other small scanner is outdated and has outgrown it's usefulness. It is small and easy to carry in my pocket. This scanner far surpassed my expectations in terms of usefulness. I bought a larger tablet sized scan tool for the heavy diagnostics. The small scanner does a lot of what my tablet scanner will do, for less than 10% of the cost. It only abbreviates the words to make them fit on the smaller screen. So if your trying to explain to a customer what is wrong with their vehicle, you need a bigger screen. In my opinion this scan tool is well worth the $25. I was not disappointed!

For a non-bidirectional scan tool, this unit offers an amazingly broad array of functions including live data. I got this to leave in one of our vehicles when taking a road trip. I have yet to have a check engine light come on while traveling...but in case it happens then I'll be able to diagnose whether it is a serious issue that needs immediate attention vs something not worrisome that can be dealt with when we get home. At home, I have access to more sophisticated bidirectional scan tools (and much more expensive) that I do not want to travel with in case the car gets broken into and they get stolen.

To be fair and give credit where credit is due, I got this on the recommendation of Scotty Kilmer and he was right on the money concerning this product.

john

If an "idiot" light comes on you don't know what's going on. Can cause a lot of stress. Just got it and test it out on my car with a full diagnostic. Knowing that something is minor alleviates the stress of wondering if it is going to die in the middle of the nevada desert or utah desert or in the plains of wyoming.

This scanner gave me more details on tire light on and indicated that the pressure sensor may not read correctly. After checked my five tire pressures, it confirmed that one pressure sensor was bad. Knowing this is minor alleviates my stress. It is a great product. Worth it.

Peter

I tested the stool on my Toyota Sienna
It worked great! The live streaming was very nice to see. For a low cost scan tool it has a lot of good features.
I would recommend this tool to anyone looking for inexpensive scan tool.

Hello all, I was getting annoyed by the fact that I had to constantly go to AutoZone or PepBoys in order to find out why the Check Engine Light (CEL) was on. Sometimes they would even charge me to do so
So I went ahead and did my research on which one I should buy. I was looking for a scanner that would be able to read ALL vehicles that has OBD II, ability to tell me that code and what the code means, and the ability to clear it. This scanner did all of that and I'm very happy with my purchase.
Here are some things that I did soon as I got the device in the mail. I downloaded the program form their website (Maxi-Link v1.04) in order to update it to it's latest firmware, plugged it in with the provided USB cable, followed the steps and it was up to date! And to my surprise they even had a DTC Lookup manual in their program in case you forgot what the code description was or if someone knew the code but didn't know what it means, this was extremely handy to have. It had P0, P2, P3, U0 and U3 within the DTC lookup, codes with P1, P3, and U1 you would have to do research as they are manufacturer specific. Another neat feature is that this scanner allows you to view freeze frame data and the I/M Monitor is very useful also.
The LED screen is very nice to have as some scanner don't even have a lit screen, even more expensive ones doesn't sometime. But I only wish the buttons like ENTER/Exit and Scroll were lit also but it's not something that I would knock off a star for.
As I said before, I did a lot of research so here are some reasons why I chose this product over the others.

JOhny

I used it on my 2010 Toyota Prius, found a code telling me to replace the hybrid battery, took it to Toyota, they confirmed it, and just waited on my decision for the dealer to replace the hybrid for close to 5000$ dollars, 4000$ battery, 600$ labor, and I would be charged for disposal of the battery also. I research using the internet, decided to take my car back from the Toyota after paying them 120$ for basically nothing I couldn't do myself in this case. I drove my car home plugged the scanner and erased the code, after doing so the car started and it's still working like nothing happened. I had several lights, and the hybrid had stop working, it was running on gas 100% of the time,now that's all goan. I purchased another scanner (cellphone bluetooth type) that let's me check the condition of all 14 sets of hybrid batteries and they all are working properly. Very happy with this device, a few coworkers used it and found it extremely useful (check engine light)
Sorry I wrote this using my cellphone just after waking up, hope it helps.

Has worked well when the check engine light comes on. I had an issue with my coolant thermostat and was able to diagnose it before visiting the mechanic through the web with the code I got and the symptoms I had. I wanted to see if the new mechanic place was going to be honest (I just moved to a new state), so I didn't say anything about it except the check engine light went on. The mechanic told me that was the issue and nothing else, I knew I found a good mechanic.

Just trying to help =)

Like I said in the title, this works on ever car I own 2007 and up.
The price is so cheap and it works perfect. Plug it in, pull the codes, google the codes and find the issues.
Can also reset with this.

This little handy device will save you SO much trouble and money if you have a slightly older car like mine that has fairly regular check engine lights.

I use this (and let all of my friends use this) ALL the time. The device plugs right into your car and has simple instructions to diagnose any problems your car is experiencing or dashboard lights that come on. Once the diagnostics have completed, it shows you the error codes your car has produced, and you use their handy booklet to decode and identify the problems you are experiencing.

Once you have the code, you will probably have to do some research on exactly what might be going wrong, as some of the descriptions are brief or beyond my knowledge with cars, but there's plenty of online resources that can help with this.

I saved money and time by using this to diagnose my car and fix it without having to take it to a mechanic, who often charge a fee just for running this EXACT diagnostic test! This device also gives you the option to reset your car's lights to see if the problem is persistent.

All in all, this is a super handy piece of equipment for an incredibly reasonable price. Be careful though, you may find that all of your friends want to borrow this from you all the time! Not a bad problem to have.

Let me know if this review was helpful, or if you have any questions, and I'll try to respond to any that you might have!

Our vehicle hates multi-state road trips with different gas octanes along the way. Did you know that cruise control doesn't work when the check engine light comes on? This was a LIFESAVER on a long trip. On our way there, we had to stop three times to have it read and/or cleared - first, the initial panic after the light came on ~30 minutes after getting gas in a new state (and they wouldn't clear it). Second, the dealership diagnosed the "minor inconvenience but safe to drive" problem, warning us that the light would come back on if the engine was turned off. Third, because you have to eat sometime.

Trying to drive long stretches of highway without cruise control on a 30+ hour trip is NO FUN. We had this delivered to our destination and it paid for itself on the way home. We are learning to care & maintain our vehicles ourselves and this has been a useful tool. Diagnoses and clears codes easily. We've owned it for ~8 months.

Better than I had hoped. Excellent product, easy to understand, easy to operate. Doesn't even require batteries, as it works off of the car's system. So it's always ready to use. Takes most of the mystery out of those annoyingly vague trouble lights. Bought this model because of numerous good reviews from various sources and it lives up to its reputation. You can pay more for other models but why would you want to ? Seller was prompt and professional. Item arrived within a couple of days. I intend to keep this in my glove box at all times.

I used this to check the A/F and O2 sensors on my truck to determine if the sensors were bad or if I really needed to replace my catalytic converter. The I/M readiness information is useful when you are preparing for a smog inspection.

I was using an OBD2 scanner that linked to my smartphone but unless I wanted to pay much money for an app that gave me more than the elementary functions it did not do enough. This Creader has many features and easy to use. No need for batteries as it runs off your car's voltage. The screen is bright and very easy to read plus it has lots of features that my old one did not have unless you paid for a better app.
