2021 IC psi gas. driver reports random red brake pressure light. replaced sensors pressure bled brakes many times no air. might go for weeks and not come on. brakes feel ok to drive, nice solid pedal, abs works as it should. what conditions need to be met to make the light come on. any thoughts on this.
if anyone has been into it before, check pin tensions esp at the bcm and the diode pack. we fought with one for a while and some one stretched the pins at the bcm....
rectifier diode allows electricity to flow one way only so it must be allowing power from pin 30 to back feed the pressure circuit and illuminate the warning light with pressure in the circuit(depressing pedal) not even sure if I looked at the right wiring diagram but for all your IH wiring here's a good link https://www.international.com/products/resources/tem-body-builder/body-resources
