False SRS and Tire Warning Indicator Lights - Toyota Nation Forum : Toyota Car and Truck Forums

Sorry if this has been discussed before but my SRS and tire inflation warning lights have been intermittently turning on. I checked and both are ok. Battery voltage after driving and after being parked overnight is between 12.5 and 12.9 volts.

TIA,

could be a loose connection on the wires or the sensors. i would tell you how to check that if i knew where they were and how to get to them, but i havent gone that in depth in the matrix yet.

Tire pressure indicator problem cleared. I gave the wheel areas a good pressure wash and reset the indicator, so far so good after 100+ miles. I guess some sensor was getting bad readings from accumulated dirt...
