DRL Turn signal bulb not working

my drl lights stopped working, i have a 2017 Tacoma Sr. i brought it to the dealer, he said my warranty was void because i changed my headlight bulbs to led's. i also added a separate fuse block for the extra lights i added, separate switch's, has nothing to do with the truck. i traced back the wiring diagrams and they go into the instrument cluster. i have had issues with that also, when driving needle skips sometimes, once it didn't register mph till i shut the truck off. i was wondering if the multiplex node is in the instrument cluster? also is their anyway to be able to get into the multiplex system to see whats going on inside? i have a Snap-on Solus Ultra, but that is only good for checking the diagnostic codes for the engine and stuff. any help would be appreciated.
