I have a 1997 Subaru Legacy. When I plug in my scanner to the OBD2 port,
the slightest little jiggle in the cable will kill the power to the
scanner and then it has to reboot. I've tried another scanner and it
does the same thing. Is there an easy way to tighten up the pins in the
car's OBD2 port so that it stops cutting out?

Thanks for your replies.

It's old. Maybe the surface has got some contaminant.

Contact cleaner spray?

I think I already tried the DexIt spray. It's been touchy for so long, I
don't remember. I'll give it another shot.

Replacement OBD2 plugs/sockets are readily available, as are videos on
youtube on how to replace it. It is probably not worth farting around
with the plug unless you have the correct pin extraction and crimping tools.

Most connectors are good for 20 to 100 insertions after that they
deteriorate gradually or rapidly...

So if I'm not extracting and crimping in new pins, how am I connecting
the old wires to the new plug? It occurred to me that if the entire
display is going blank, that would indicate that the 12V supply pin
and/or the ground pin is cutting out. Correct? That shouldn't be too
hard figure out. I do find it amazing that after 20-100 insertions, the
plug's integrity would be compromised.

Thanks for your reply.

The spec sheets for crimp pins and connectors is eye opening...many
Molex pin connectors are only rated for 25 connections - after that it
is anyone's guess how long they will last. Amp and other connectors are
much the same.

Heck even electrical outlets start to fail after 50 or so insertions -
ever notice how a socket you use for the coffee pot feels looser and the
plug seems warmer than it did when they were new?
