OBD II port issues

[myfast70]

I just picked up a scanmaster and cannot get my OBD II port to work with my car. The unit will power up and show the versions but goes dead after that. I just checked it in my buddies car and it works great! I pulled the panel down and removed the plug and found everything to be ok with it. Does anyone have any advice as to where to start the troubleshooting process? I know the port has power as it starts the unit fine. After talking with the Scanmaster on it they thought my port was bad. How can I verify this? Is there a pin on the computer that I can check continuity with the wires on the port? I'm guessing if I did that I should dis-connect my PCM first? Any help would be great! My biggest reason for posting this in this firum is that I will be purchasing HPtuners in the near future and would like ti make sure my port is unctioning correctly.

Anyone have any info at all??

Does this scam master thing hook up to a laptop? Are you sure it is not getting power from the laptop? The reason I say that is most of the guys on this forum that claimed the port was fine but could not connect ended up finding a blown fuse that powers the port... its worth a check... Goodluck.

No laptop! It's just a scan/display tool.

Does the cigarette lighter work? If it doesnt, you have a blown fuse. Had that happen to me once before.

Grab a test light and check pin 16. Should be batt voltage, that's what powers up most adapters. If not start checking fuses.

Refering to aldl pins-
