What is going on here? Dave, could your TPMS system be 'out of order' altogether? If you bleed a tire down to 20 psi, then drive a mile or two, does the light come on?
It is fine, the safety test was in 2011 when I got the car. The light goes on when the air pressure gets too low. These batteries are nearly 16 years old now as the car was made at the end of 2004.
