Normal readings at Data Link Connection?
Anyone know what the normal readings would be at each of the pins when probed with a multimeter? KOEO

I've got...
pin#2 0.2v
pin#3 10.8v
pin#7 1.5v
pin#10 4.8v
pin#14 2.4v
pin#16 12.6v

It's a data port, that follows the automotive "CAN Bus" data standard.
You will only read a stable voltage from the power & ground pins that would normally power an OBDII scanner. For all of the other data lines, the multimeter is going to read an in-between voltage that is an average of all the ones and zeroes that are toggling by it.
Here's the pin out description of the OBDII connector

The easiest check is to plug in some sort of OBD-II Scan tool - standalone, phone or tablet-based, or laptop based scanner. Do you have an Autozone; Pep Boys, etc., near you? They will scan your vehicle for free (or minimal cost). If there's something wrong with the data port, the scanner will flag it in about 20-30 seconds. (Communication Error).

my guess is you tried to plug in a scanner that requires the OBII plug to be powered up but because the fuse is blown the tech said your OBDII port is dead LOL If this is the case then you only need to worry about #4 ground and #16 Battery ..... power is usually the cig lighter or power port fuse

Yup. IIRC it's F2.12 under the steering wheel.
