I have an AutoXRay scanner that does OBD I and II, but for some reason it recently will not link up with the Maxima (though it works fine with my wife's Mazda and other peoples' cars).
For the Maxima, I picked up an Actron OBD II scanner from Advance Auto. Pretty inexpensive and works great to read codes, tell what the code is for, and turn off the SES...
I have the Pocketlogger and an old Handspring Visor. Works with most cars and can sample at higher rates if the ECU can support. Saldy the 4th gen isn't one of them and you can't get faster than 3 samples per second. But that's only important for dataloging and such.
just got an Actron OBD II. the box says that it works with 96 and newer but ive got a 95 and seems to work fine. do i need to have the OBD I instead of II
