The SUV does not have a relay for the brake lights, only the pickup trucks.

I am assuming you have an issue with the brake lights so I am attaching the wiring diagram plus here is a guide that will help with testing for voltage:

If the lights are not working, then check the stop lamp switch.

See the diagrams below and let us know what other info you need. Thanks
