Disabling the Light.
Warning Light Behavior.
- Blinking - This means the TPMS has malfunctioned. One or more sensors may have failed or lost communication with the ECU. Reasons for sensor failure may be a dead battery (in the unit), damage, or failure from natural wear and tear. Most sensors are rated to last 7 or 8 years.
- Solid - A solid indicator light means that one or more tires is operating at an unsafe pressure. Check your tires!
Older Vehicles (before 2008)The distinction between a solid and flashing TPMS indicator was mandated as part of the TREAD act in 2007. Vehicles with TPMS manufactured prior to the TREAD act will not necessarily follow the solid/flashing protocol as described above. Check your vehicle manual or ask an automotive professional to find out more.
