Asking how to setup the meter for this specific test means I shouldn't work on my own car? I'm not very versed on electrical issues but I think you're right in that my answers probably won't be found in this thread/site and I should probably look elsewhere.

I didn't say that. I said that if you couldn't figure out how to set it up with the information provided by me when I Google'd that for you, then you shouldn't work on the car. There's lots of information out there; either you're too lazy to learn, or you can't understand; in either case you should take the car to someone else.

I've tried searching but haven't found much on this issue. My car has a random "Low Brake Fluid" light that will occur after a few minutes of driving, or at startup. This warning causes the service traction system warning as well as others which leaves traction control disabled until the car is restarted. This is extremely annoying and I'm not sure what's causing it. I tried replacing the sensor under the brake fluid reservoir but the problem came back after a few days. I've noticed messing with the harness for a bit can cause the warning to go away for a few days but it always seems to come back. Has anyone else had this problem before? If so, what is the fix to correct this issue?
Because its intermittent.
You can test wiring all day long but if its in the "im working now" mode u cant find the fault.
In years as a GM/Honda tech seen it many times.
Key word here for "throwing a part at it" is intermitent.
Too much caffine 2day thought id put my 2cents in.
Best of luck my friend.

I would throw a fluid level sensor @ this so fast ur head would spin.

I have now isolated the problem area after more troubleshooting and believe the car is potentially fixed. It's gone through several key cycles with no light/warning but I'm not going to celebrate until the problem doesn't reoccur for a month or more. Thanks for the help/suggestions given.

If there are any connectors in the circuit, unplug them and inspect. If you have even some minor issue it could cause your problem. With time, a bad connection can cause the resistance to go up do to the current flow raising the temperature. I am just grabbing at straws, not sure this explains why the light gets brighter with time.

The under hood fuse block is where the problem is isolated. After moving it around the light has stayed off for some time. Which wires would be related to the circuit that controls the brake fluid level sensor here? I see several purple wires and would like to further inspect it to make sure my fix is permanent rather than a bandaide. Does anyone have a diagram?

Then as was previously suggested, educate yourself on the use of a multimeter. You'll be testing for continuity and/or high resistance.
