I have a 2002 ep3 - CDM with DRL. I recently re soldered the DRL module because my DRL wasn't working. For a couple days all of the lights worked fine, but now the passenger side high beam isn't working. I've swapped the bulbs and relays for the left and right side and they are definitely not the problem. And the fuses are all good. I've tried to check the voltage at the headlight plug, but I don't really know what I'm looking for. Could someone tell me what wires or tabs in the plug I should be getting voltage at for high and low beams? I assume one is a ground, one is low, and one is high?

 

If anyone cares: I re soldered the DRL module and did a better job this time. Everything is working now.
