Intermediate fault codes speed can network, TCS off, ABS and check engine light comes on?

Yes, they all came on while driving. But went away when restarted the car. Scanned car and showed no faults when I did the full system scan on the topology tree. Went in individual modules and got those codes. Checked resistance at pins 6 and 14 on dlc and got 61ohms. Waveforms on scope looked normal, both can hi and lo at 2.5 and hi went up to 3.5 and lo went down to about 1.5. Cleared codes and was fine for couple days but came back. Repeated same process, checked voltage at pins 6 and 14 with multimeter. Got 3.33 on hi and 2.79 on lo. The only difference this time was got a b2982, b1322, and b1284 codes, cleared codes. All went away. Decided to press parking brakes after a few times of pressing and releasing parking brakes all lights came back. Tried clearing again but only the 3 body codes stayed took a couple times but finally cleared. Monitored scope waveforms again everything normal. Everything was fine for another couple days. Now all back on again. Any suggestions would be greatly appreciated. Thank you. I have a wiring diagram from shopkey, if there's one you can provide for me to compare would be awesome. I've gotten different diagrams from different sources before.

Parking brake switch was replaced, didn't fix it. But ended up figuring it out, short on couple wires going into BCM, which was located next to parking brake pedal, when I was pressing and releasing the parking brake I must have hit the harness just right to trigger the lights. (Had kick panel all apart BCM and harness was hanging)
