OBD diagnostic tool does not connect to a commercial truck's 16-pin port because the port is non-standard/proprietary.

Standard OBD2 scanners are universal for passenger vehicles but commercial trucks use proprietary connector pinouts even with 16 pins, leaving owners without a one-size-fits-all diagnostic tool.
