hello, my rear trailer camera randomly stopped working. trying to figure out if it's a truck issue (2020 sierra 3500), or a camera issue. the other day the check engine light turned on and in the error code history report they gave me, i see the following: Code - B399F Description - Rear Trailer Camera Supply Circuit Short to Ground Failure code - 02 Status - history when first installed, the camera worked fine. i noticed it stop working when we were on the road. Anyone know what i could check on either the truck or the camera to see where the wiring issue might be? the dealer hasn't been helpful.

Thanks Mbower2020, that's what i figured but wasn't 100% sure. it's a bummer, but at least i'll know if they drop under 102 i guess.

similar, but unrelated issue i have. is there any way to increase the PSI reading on the sensors/truck? the max reading on my sensors is 102, but i need my trailer tires inflated to 110 PSI cold. the sensors are still helpful for tire temperature, but wondering if there is a workaround to increase the pressure reading?
