2.3 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.
