Hi, according to the original protocol the red brake warning light(it's not only for handbrake) should be part of the 3 amigos(actually 4) all the time but in reality it's not, the SLABS used to make tricks in this area... i've seen 4 amigos not once(they come usually for sensor open or short circuit faults) and other kind of combinations like yours too as well, first of all make sure you have brake fluid in the reservoir to make sure that the red warning is not triggered by low fluid then watch carefully if you see the amber HDC light on ignition self test... anyway what ever you do the only certain way to find easily the issue is by plugging in a tester
