TPMS (4th gen) - flat spare tire, no TPMS light
I know a solid TPMS light on a 4th Gen means low pressure on a tire, and a blinking TPMS light means a bad or missing sensor, but what if the TPMS light doesn't come on at all despite a tire being totally flat?!
I know TPMS works for my four regular tires (at least it did last month when I lost some air on one tire) but today I dismounted the spare for new tire installation tomorrow and to my surprise it was totally flat with no TPMS warning at all. So I inflated it to about 20psi and still no TPMS warning light, blinking or otherwise
My only thoughts it the TPMS indicator bulb or fuse is blown, because otherwise it's like the system essentially just disowned one of the five sensors.
