DRL relay was the issue. Appreciate the collective insight. Still not fully sure why the relay was not making a good connection. I'll peel off the cover on the relay and see what's what. Again...thanks for the collective help.

100% positive DRL relay is clicking. Not only do I hear an audible "click". When I put the relay on the bench and put power to pins 9 & 7, I can see the ohms drop between pins 5/6/8, with 6 & 8 being the pins that the relay switches between.

My module I meant relay. Located in the fuse box.

Alright, after some testing the bottom line is that the high beam circuit is working. I tested the ground connection, coming from the DRL module, and it tests out. With the high beams on, and the DRL module in, the high beam circuit does not work. However, if I remove the DRL module and turn the high beam circuit on, I get 14v going all the way to position 5 of the DRL module. If I put a jumper from 5 to 6 or 5 to frame ground or 5 to battery negative, the high beams come on. So at this point, I'll assume that it's the DRL module that's issue here. Again, I put the module on my variable power supply, along with my multimeter, and everything tests out voltage and ohm wise. Obviously, I can hear the relay switch when the power is supplied. I'm gonna put in a new module and see if that's the kicker. It's all very odd that it appears to bench test fine but has issues closing that 5 & 6 position to complete the high beam circuit. Note here, the 14v at both pins of the LH high beam lamp through me for a loop for a hot minute. After looking at the wiring diagram, it makes sense now being that the RH high beams are tied into that circuit, which runs to the position 5 of the DRL module. It makes sense to have it built that way so that if a high beam lamp goes out, it does not effectively kill the circuit.

OK, removed DRL relay; High Beam relay; High Beam lamp along with High Beam (LH side...easier to work on) fuse. Traced line all the way to high beam and all checks out good. However, when I went to run a voltage check with the Low Beans on and High Beam switch activated, I had 14v from the fuse to the Red/Green line as indicated in the PDF (not sure what service I can use to attach thumbnail here). However, I still have 14v on the other line coming out of the lamp connector. What's even more odd is that I still have the DRL relay removed. So.....for some reason positions 5 & 9 on the wiring diagram PDF (see page Headlight System / HL-03) were getting 14v. 1) with the relay removed I don't see how those positions are getting power, at least from looking at this PDF and 2) as per the HL-01 page, when the head lamp switch is set to low beam and not Auto, the high beam lamp should be bypassing the DRL circuit and going straight to ground. I'll keep poking the bear on this. Also, car was running for a bit doing this and I guess there's an AT Oil Temp thing and it kicked me this error. Now the key is stuck in the ignition and it won't shift out of park. I guess a cool down is necessary?

Yeah, DRLs stay on. Last night I came across a service manual PDF that goes deep in the weeds on the entire electrical system. I'm going to start poking around that DRL relay connection on the fuse panel to see if I can track down, what appears to be, a ground issue. Appreciate the input so far. I'll keep the forum updated as I get updates.

Yeah, grounded to the neg post near the fuse panel. Also, did swap the relay (both high and low...just for good measure). No changes to the high beam situation. Also, checked fuses for the Body Integration Unit (fuse 7 and 12) and those are good. Appreciate the, attached pic. I'm not working off any wiring diagram so I that helps to visualize the layout. Yeah, I was just about to dig into the actual relay recepticles. 1) to ensure power and two put a jumper in there to see if that changes anything. Appreciate the input.

All, First time posting on the forum. I've searched this forum, other Subaru forums and the open net for the issue I'm running into and I can't pin down what is going on. Summary, High Beams do not work. Low beams work fine. DRLs are fine. I noticed a few weeks ago when I was driving the high beams were sporadically coming on/off when I was hitting the switch. Now they are fully non-operational. Here's what I've done/tested: - All high/low H/L fuses have been visually inspected as well as ohm'd out. No issues. - Confirmed 14v coming to the fuses when switch is engaged. - All high/low relays have been ohm'd out. No issues. Also, you can hear the relays engaging when the switch is activated. Also, replaced the relay with a new one, just as a CYA. No changes. Working. - DRL relay works as advertised. You can hear the relay engage when turned to Auto. Put it on my variable power supply and ohm'd both sides of the relay. No resistance. Working. - Removed the DRL module from inside the front left wheel well. No changes to the high beam issue. - Pulled the high beam lamp and visually inspected it; ohm'd it out and put it on the variable power supply. No issues, bulb is working. - Ran an ODB scan just to see if it kicked any electrical component failures. It did not. - NOTE: on the high beam circuit, I noticed that when the high beam is engaged that the two leads going to the bulb are both showing positive 14v. This one is throwing me for a loop. I can't say that I've see a circuit where both leads were showing positive voltage. Maybe someone can enlighten me on this one. This is pretty much where I'm at. I've got a service call schedule this week for them to run a diag on it. Aside from all of the above, I'd welcome any input from the forum. Thanks.
