My T550 has an intermittent issue where the parking brake will trigger and an M1607 error is displayed. By turning the machine off overnight, I can usually get the error to clear. About a month ago I had the dealer replace the brake solenoid. I've checked the fuses. Is the brake relay the next logical thing? Guidance on where it is located would be much appreciated. Or any other suggestions.
I'll order two $10 relays to swap out the bad one and keep one one hand as a spare.
