TPMS Tell-tale Light
When diagnosing TPMS systems, you should understand what the TPMS
tell-tale light means.
When turning the ignition OFF to ON, the TPMS tell-tale should come on,
and then go off, which indicates the system is working fine. If the light stays
on, there would be a pressure problem. If the light flashes, there would be a
system problem, which can range from faulty sensors to sensors on the
vehicle that haven’t been learned to that vehicle.
