Ok. Just bought a clean 2008 SC and after 30 miles the pressure system detected low pressure and started blinking. After filling a low tire the system is still indicating a problem. (also checked the spare) Is it coincidence or is there a low tech way to reset it or a way to trouble shoot it. With all the searching i tried nothing came up on it that was in the least bit helpful except that the module is in the front headliner? Seems like there is a scanner to help test? reset it.
