Check the wiring before you throw an ECM at it. Since it sounds like you had an issue after a hard hit on a speed bump, it could be a chaffed wire issue or a poorly installed connection than a hardware issue.

Not to say that a shorted wire couldn't have taken out the ECM.

Test light to OBD port lights on one of seven // after manually entering vehicle info //;No number or ID shown for PCM // shows xxx-xxx
Variable of ABS info shows up
Does this show communication to ECU??
U it could still be functioning problem limited to link to diagnostic port??

So focus on this section of wires?

Check fuses. Usually the cigarette lighter is on the same circuit as the test port. If whatever circuit the test port is on has a blown fuse, you get no communication.

Side note, the way you are writing this stuff out makes it hard to follow.
