Hello,

The system doesn't work like that because the daytime running lights run run by the BCM the same wires are used by the headlight system here is a guide to help you test the wires and the headlight and DRL wiring diagrams so you can see how it works.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

The passenger day time running lights are not coming on and tail lights only work when the brakes are pressed and blinker works hazard lights work and when the key fob is pressed all the lights come on I have replaced wiring pig tail and tail light junction box checked fuses and replaced bulbs and all lighting works thank you

Okay, if I am reading this correctly. The right DRL is not working and the tail lights only work if you step on the brakes. But the turn/hazards work in the rear.

When you turn on the headlights do all of the high and low beams work?

For the tail lights it sounds like a bad power feed from the brown wire.
Check the park lamp relay in the under hood fuse box to be sure it is okay. Then use a test light on the brown wire at the rear light junction box. If you have power there then look at the brown wires at each tail light. If you have power at those then verify that the grounds for the lights are good.
