Customer Reviews

Very easy to use.

Will not connect to any PC- I tried 3 computers, XP and Win 7, with old and newer downloaded software.

I contacted Autel USA asking for support on the unit.

I am a retired automotive tech and shop owner, as well as a 35 year FAA Aircraft Airframe and Powerplant mechanic (as well as FAA Maintenance Inspector), so I pretty much know which end of a wrench to grab, and have seen a lot of technology.

I needed a graphing scanner to find a problem that freeze-frame data just wasn't picking up, so despite having several other scan-tools, I decided to try an Autel MS-509.

I must say that I am AMAZED! This thing has exceeded my wildest expectations in spades!

I have a 2001 Volvo that was suffering from severe surge and hesitation, and NOTHING would pin down the problem, including the dealership's many-thousand-dollar VIDA computer system. Volvo recommended replacing the coil packs, the plugs, and the MAF sensor just to narrow down the usual suspects. Not cheap!

Hooking up the MS-509 and using the super-simple menu (very intuitive vs. other units that I must have the manual open to use), I was able to graphically depict ALL relevant parameters (PINS) and by observing them live while driving the vehicle, the cause was immediately obvious.

Needless to say, I now consider my other scanners and code-readers surplus (including two that cost considerably more, and the other that cost a multiple of the Autel unit).

I sat in total amazement holding this unit in my hand using its ability to live-chart virtually any functions I wished (among them MAF, Throttle Position, Ignition Advance, O2 Sensor Readings, RPM, and MORE).

Simply the MOST analyzer/scanner I think you can buy for (double or triple?) the price!

Autel MaxiScan MS509. A previous review was heavy on critisim for this unit. The problem the previous person had was that Toyota utilizes the J1962 OBDII connector on vehicles that ARE NOT OBDII compliant. Unfortunately you have to be a qualified mechanic who is in the game like I am to know this.
I use the MS509 in my workshop on all late model OBDII vehicles. The unit is fast uplinking to the PCM and just as quick checking for codes. Freeze Frame Data and Live Data are easily accessable and the little apprentice boy likes it because if he cannot understand the sensor code (i.e. IAC) he can push the ? mark button and it explains to him what he needs to know.
I have done one upload if updated software and it is pretty brainless to do.
Would recommend that you know a little bit about what your doing before to do any diagnostics on your own vehicle if you are a Do It Yourself handyman. Otherwise you could cause yourself grief and post reviews that are not a realistic evaluation.
Awesome Product for the Money.

Verified Purchase
We bought this unit to check our fleets short term fuel correction by measuring the oxygen sensors voltage readings which it states it can do.
However, it wouldn't communicate with our 2006 Ford F-250 SD or two 2005 Ford F-150. It comes up with communication link errors so we contacted Autel by e-mail. Nothing! Then we went to their site which has a complaint form which we filled out and hit send... only to find out that it is a false front. Again, nothing was sent. So, we printed the form and filled it out explaining what our problem was and E-mailed it to their support E-mail posted and have heard nothing.
My suggestion would be... Run, especially if you are working on Ford pick ups.

What we found really interesting is how Amazon has stepped up to the plate!
They have sent me a return label and are taking it back.
They have also tried to contact Altel (in China) and tried to use their web site and have had the same success we had.
Amazon! You are Stand Up! Thank you!!!

I am reviewing the Autel MaxiScan MS509. I had done a considerable amount of research on ODB-II scan tools. The big consideration was do I look simply for a code reader and reset device OR do I look for a real-time diagnostic tool. I had no less than six different models from various manufacturers on my "short" list. Previously in the automotive repair industry I was familiar with the protocols with OBD scan tool devices. I spent time reading Amazon reviews, OBD forum sites, youtube etc. [I went through a lot of Visine from staring at the PC monitor for extended periods!]. I went with this model largely on credible reviews, features and price. Amazon's price is respectable but if you dig into the issue you will be able to find one thru an importer. I got mine direct from where they are made overseas [$60].
I just received it and these are my initial impressions: Good heft and build quality, feels like a real "professional" grade tool, came with all the accessories you should need except 9V battery. I hooked it up to my wife's '99 Jeep GC which is supported by SAE J1850 protocol and was able to quickly navigate the tool set up and DTC scan/test options. The live data stream mapping is a great feature. I will be trying it out on my '09 Dodge Ram which is CAN supported and should get even more information from that protocol. This spring/summer I plan on scanning as many of my friends and neighbors cars that I can to get proficient with it. I will make occasional updates as I work with this tool. I know some folks have had issue with specific scan tools, the only bad thing about reading too many reviews is that after awhile one goes into "information overload" and you have a hard time making a decision.
