I've got a 2006 Suburban 1500 and I've been fighting this darn TPMS light for a few weeks and i can't seem to figure out why the light won't turn off I've replaced all the sensors and done the whole headlight switch on and off relearn thing and letting air out till the horn honks thing and I've done it with a tpms activator tool when i did the relearn with the tool the light went away for about 45mins then came back my scan tool says all the sensors are programmed and have good battery i also have disabled the spare tire monitoring using my scan tool as i do not have a spare

id be grateful for any input on what else i can do

 

you need to run a diagnostic scan using a TPMS capable tool
