Cannot tell from the partial wiring diagram included in the 270 SDX Owner's Manual, page 43 of 48, but there is probably an array of circuit breakers at the helm.
Thanks for the info. No breakers for the tabs by the battery. I suspect the breaker is on the back of the dash but it is very difficult to get back there. It’s a tight spot and hard to see.
Just did this myself on a 2021 SDX. It was an inline fuse behind the helm. Not that hard to access but a little difficult to identify. Trial and error mostly.
The fuse will be in the fuse panel behind the helm. It will be a 20 amp fuse, one of the few 20 amp fuses in the fuse arrangement. You likely caused the fuse to trip because you pressed the two trim tab buttons in opposite direction at the same time, one up and one down. That will blow the fuse every time.
