I don't think we saw the same thing, what I see was linked is this:

.: Products: 12 Pin ALDL OBD1 Bluetooth Scanner / Code Reader / Adapter (MK II) and ALDL Scan App

.: 12 Pin ALDL OBD1 Bluetooth Scanner / Code Reader / Adapter (MK II)


I haven't seen any 1994/1995 able to flash codes, and I know they don't flash out Pxxxx codes.

If you haven't already however, I really do recommend giving a good check to the power feeds, especially the ones going to the power distribution blocks. My 1994 Regal has a block next to the battery that keeps working loose, and when it gets loose, it causes all sorts of odd behaviors, including the voltage not running where I want it to be.

I'm hesitant to throw an alternator at this point, and still recommend a full charging system test. Even a bad battery can affect voltage.

If you short the right hand pins on the ALDL it will flash codes through the CEL.
That thing is called a scanner which it is not as a scanner will provide real time data.
That thing says 'bluetooth' and yet is is direct fit.
It'* junk.

If you short pins a and b the cel will flash codes, i have pins a k and m, so no shorting.

It is bluetooth to my phone where it displays things like rpm, fuel pressure, vacuum, etc etc etc every few milliseconds

I stand corrected. I never seen a bluetooth scanner that had a monitor. I thought the led in the end of the devise blinked like the cel.
Ok. You have scan data available. Look under codes and you will have an erase codes view freeze frame etc.
Did you disconnect the battery? What codes show with KOEO?

Not exactly tomorrow but still.

Issue clearing codes, went as far as disconnecting the battery for 24 hours, still would not clear out.

figured out one of the stored codes however, the P0117 coolant temp low and P0118 coolant temp high was caused by a damaged su102 coolant temp sensor, the head was completely snapped off.
