[Shop-talk] OBD2 Scanner recommendations

[Jim Juhas]

Pat,

The Autel sensors I installed work on both frequencies, 315 and 433 MHz, 
and from what I found, Mazda uses 315 MHz.

I also found a procedure at Bartec that said to turn on the ignition, 
then turn it off, wait 15 minutes and then drive over 15 mph for a while 
and everything should register. It didn't. I tried the same steps but 
with triggering the sensors with the exciter tool I had purchased for 
this purpose, but that didn't do it, either. Bartec has a variety of 
tools for this, some priced under $200 and they are the only supplier I 
have found so far that lists a 2024 Mazda 3 in their literature.
