AL539 AutoLink OBD ll Professional Electrical Test Tool

Before I bought this Autel 539, I got the Innova 3040d. It was a little bit disappointed because the interface of I/M readiness was not easy to see; moreover, it operates slow and hard to navigation in my opinion. The Autel was very well package; I mean it is very impressive and high quality from the package to the scanner. Unfortunately, I cannot upload the picture because of my laziness. My main concerns when I bought this Autel was the I/M readiness for state emission as I am living in California, and the version of the Autel. The I/M readiness is very easy to look as the picture of the product. As I was searching, there are two versions of the Autel 539. However, when I look on the picture of the product, it doesn't show the version and the package, so I decide to choose Amazon.com seller. At least if any thing happens, I can return it, and Amazzon.com didn't let me down. I got the newest version. In addition, the cable is long enough and firmly. The user manual is very detail. I can't not happier!

Works great, had to look up the manual for this model though.

accurate tool

As far as OBDII scanning is concerned, this tool is great. It does do all 10 modes of OBD2 (as long as the vehicle supports it). I've always found Autel scan tools to look and feel pretty solid, and this one is no exception. The included accessories, like the test leads and carrying case, are nicely made as well. The interface is pretty the same as other Autel scan tools: It is easy to navigate but its slow, partly because one must navigate through at least one unnecessary/redundant prompt page before accessing desired information. Also, the interface lacks some necessary user-controls, such as the graphing functions which while great are also seriously handicapped by continuous autoscaling that can not be turned off or controlled in any way (this makes spotting trends or abnormal sensor data very difficult). The multimeter functionality works as it should. It even gives you a simple oscilloscope/waveform display when performing voltage and current measurements and also displays frequency and duty cycle information on the same page. Unfortunately the utility of this is limited by the narrow measurement ranges of the tool. The voltage measurements are limited to +-30 V, and the only form of resistance checking is a "continuity" test which only displays resistance values under 50 Ohms. In my opinion, I would like to see a measurement on par with at least your typical cheap $10 DMM.

I bought this item because of the large number of youtube vids by astal motors, Autel recommending it His detailed how to's on what this scanner is capable of, let do tests on systems normally beyond my skills I was able to diagnose multiple issues with my emissions and fuel system in my 00 frontier. great tool easy to use and very capable

Good product but it doesn't work very well with German cars like an Audi it doesn't recognize the code

Gave a quick diagnostic with a code reading identifying the problem. This was for a Toyota vehicle. The readout identified the problem code as well as converting the code to the specific problem. I am going to plug into my daughter's jeep in the near future. I expect the same result. The unit came with everything needed to function.

This scanner is much faster than the ms509 and the connection is constant without dropouts. This is not the one that has the battery test built in but you will be able to perform the start and charging system check. The leads that come with it are good quality but the obd2 connector has weak prongs on the ALDL obd2 male connector side so be careful not to bend it. Graph is ok to check for problems, has no way to set parameters, it is intended for a quick and fast view. Battery works great and retain last viewed vehicle information for you. Delivered was fast and it came in original box, seller answered all questions prior to purchasing unit. Thank you.

No es la vercion mas completa pero parece que esta bien. Es una confusion con la vercion la mas completa tiene la letra b

A grandes rasgos es un escaner OBD II y una herramienta de prueba de componentes eléctricos, el cual admite los diez modos de prueba de OBD II para ofrecer un diagnóstico completo. Las opciones I/M con un solo clic, pruebas de circuitos, pruebas de sistemas de encendido y carga, son de gran ayuda para el diagnostico eléctrico de un automovil. Todo esto lo podemos observar en una pantalla a color TFT. PDA: Utilizado en un Nissan Sentra 04 Incluye: *Escaner Autel AL539 *Cables para uso del multimetro *Cable USB *Manual de usuario *Estuche

Ottimo strumento di diagnostica subito funxionante anche se la mia vettua non supporta le numerose funzioni dell'apparecchio non do 5 stelle perché il programma sul cd non funziona e il manuale è solo in inglese. Spedizione ed imballaggio ottimi.

Las funciones de voltímetro solo soportan hasta 30voltios, aunque incorpora un pequeño osciloscopio, el menú es un poco deficiente y solo esta parcialmente traducido al castellano, pero para lo que es sirve.

Aun no he explorado detalladamente todas las funciones, solo de manera un tanto superficial. Sin embargo no me funcionó con un chevy 2002
