My OBD2 won't communicate with my truck but Autozone's does

    My Ancel AD310 scanner bombs out about half way through attempting to connect with my 1999 Toyota Tacoma SR5 4WD truck. I took it (truck) to Autozone and their scanner worked flawlessly. Also, I tried my scanner on my other vehicle, a 1996 Lincoln Town Car and it works fine. I changed the 10amp fuse in the fuse box under the hood. I can't figure this out. If Autozone's scanner works that tells me that there are no issues with the trucks wiring and if my scanner works on my Town Car that tells me that the scanner is working ok. What could be preventing the scanner from connecting to my truck?

    Poor connection between your device and the truck .

    Might be some corrosion might be how the pins and sockets mesh

    Your device works on your other vehicle Auto Zones connects to your Truck

    Logic says it is in the connection.

    Not familiar with the handheld models but is it possible it doesn't support the protocol?

    that scanner is an entry level scanner and as such, it probably doesnt have the communication protocol that your Tacoma uses. I looked on the Ancel website and they dont list anything in the specifications tab. OBDII is a “general standard” interface but the function of the pins and the software is different sometimes from year to year and manufacturer to manufacturer.


    couldn't find this when I originally posted.

    https://www.scantool.net/blog/which...tly, ISO15765-4/SAE J2480 (a "flavor" of CAN).

    i hav
    I have the same model for a few years now it connects fine to my OBII vehicles. it worked for my 2017 Ford F550 with the Can systems.

    Then I have had to do some cleaning and replacing of pins over the years.

    It lives in the Truck I have never had a code trip I could not read.

    It is a simple code reader of course it does not read ABS or Transmission codes nor real time data.
