Help With OBD2 Connection

[Mkrucejr]

I just ordered a basic scanner so I can figure out why my check engine light is on...

I know where the connector is, but does anyone know what the button in front of it is for?


Thanks

That wasn't there originally from the factory.. It might be a aftermarket alarm shutoff (I see a black box to the right) or maybe or something else..

Yes, it's likely something for that alarm system you've got there. What a messy install...

IIRC, p401 is an EGR flow code..
