    Tech2 communication error

    2003 Suburban 2500, V8 6L:
    When a Tech2 fails to communicate through the OBD output port of a vehicle, where as an OBD2 scanner does successfully communicate through the same connection port, what can one infer from this? (The Tech2 functions with other vehicles, so no it itself is ok.)

    Any ideas?

    Sounds like an oxymoron. Try another Tech2.

    Tech 2 unti comes with some necessary cables, if fail to communicate with vehicle, try to hook up a 16 pin Connector for tech2 and change connect it with main test cable. Done

    Also note that a blown cig lighter/powerport socket/fuse (on certain GM models) will also
    cause the tech2 and other code readers to not read or function.
