High-beam's and DRL's not working

Hi,

I suspect it is related to either the relay or the body control module. I have attached four pics below of the system. First, I need you to check the fuse I circled as well as the relay in pic 1. You can switch the relay with a known good one or here is a link that explains how to test one:

Next, check if there is power from the DRL relay to the body control module (BCM). See pic 2.

Next, check for power between the switch and BCM. (pink wire). See pic 3

Last, check the ground between the switch and body of the vehicle. I seriously doubt this is the issue because the low beam work and they have a common ground. However, there is a splice in the wire that could have failed. See pic 4.

If everything I suggested checks good, I suspect the BCM is faulty. However, let me know what you find before moving forward,

Here are a few links you may find helpful:
