On the Intel Mac the best you can do is—

Try resetting the SMC Reset the SMC of your Mac - Apple Support see the details.


Try resetting NVRAM/PRAM Reset NVRAM on your Mac - Apple Support

(get at least two-three rounds of the chimes when holding the NRAM Reset)


Even though SMC controls the touchbar, some USB is in play,

so this would be NVRAM , notice:


USB Device: Apple T2 Bus

USB Device: Touch Bar Backlight

USB Device: Touch Bar Display

USB Device: Apple T2 Controller




If no resolve it typically points to a hardware issue with the T2 Controller/logic board.


In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment
