Do you refer to connector B pin 4? If the relay is not stuck closed, the issue is in the ECU. You can prove this by unplugging connector E, if the current drops to zero, the ECU is at fault.
I unhook the neg battery cable at home and make sure the hood doesn't latch.
The esp/bas light comes on as soon as I touch the brakes. If I restart it without brakeengagement and use the cruise control for at least an hour of driving the light goes out ,brake light works, cruise works for maybe two starts and back to esp bas lights.
Automatic or manual? And what year? (There are differences in wiring between 04-06 and 07-08; and manuals are not the same as autos.)
