How to Reset Scion TC Tire Pressure Light (2006-2016)
Set and adjust the tire pressures in your Scion TC to the exact air pressure on the driver side door panel.
Turn the engine on or the ignition switch into the run On position.
Open the glove box.
Press and hold the TPMS reset button.
Watch the low tire pressure light blink 3 times on the dashboard display.
After the low tire pressure light stops blinking, release the TPMS reset button.
What Sets Off the Scion TC Low Tire Pressure Light?
Tire puncture or leak
Temperature changes affecting tire pressure
Natural air loss over time
Damaged tire valve or valve stem
Incorrect tire inflation after manual adjustment
Tire sensor battery failure or malfunction
Impact damage or wear to the tire pressure sensor
Reinstallation or replacement of tires on car without proper TPMS sensor recalibration
How Does the Scion TC TPMS Work?
The Scion TC tire pressure monitoring system uses tire pressure sensors in each tire to measure air pressure.
Each tire pressure sensor transmits pressure data to the Scion TC’s ECU via radio frequency.
The ECU triggers a dashboard alert if air pressure is outside its recommended levels.
The Scion TC low tire pressure alert is a yellow exclamation point on the dash.
Common Scion TC TPMS Problems
TPMS sensor battery depletion
Damaged or faulty tire pressure sensors
Inaccurate pressure readings
Failure to reset the TPMS after tire pressure adjustment
Communication issues between sensors and the receiver
Corrosion of sensor components
Incorrect installation or placement of sensors
Interference from external radio frequency sources
Sensor damage during tire replacement or rotation
Software glitches in the Scion TC’s on board computer.
Why is My Low Tire Pressure Light on When My Tires are Fine?
The Scion tire pressure light may be on even if your tires seem fine due to several reasons:
Tire pressure sensor issues like battery failure, damage, or malfunction.
Temperature changes causing air pressure fluctuations.
Recent tire service without proper TPMS reset or recalibration.
System reset required after adjusting tire pressures.
Driving with the spare tire.
Marginal pressure issues where the pressure is at the threshold of being considered too low.
Mismatched tire pressure among the tires against manufacturer specifications.
What To Do If the Scion TC Low Tire Pressure Warning Reset Button Does Not Work?
To address the issue, first manually check and adjust tire pressures to match the Scion TC recommended levels. If the light stays on, it may indicate a need for a TPMS diagnostic tool to check sensor health or system functionality.
A tire pressure sensor trick that can wake up a non-working but functioning sensor is to release about 10 psi from each tire, inflate the tire back to the correct level, and then drive the car. After driving, follow the TPMS reset procedure again. Repeat.
FAQ
Where is the Scion TC TPMS reset button?
The Scion TC tire pressure reset button is inside the glove box.
Can You Disable the Scion TC TPMS?
No you cannot disable the Scion TC tire pressure monitoring system or tire pressure light.
Why is the Tire Light Blinking?
If your Scion tire light is blinking, a malfunction in the tire pressure monitoring system has occurred. This is likely due to a faulty tire pressure sensor. Use a TPMS diagnostic tool to troubleshoot.
Is it Safe to Drive With the Low Tire Pressure Light On?
No it is not safe to drive your Scion with the low tire pressure light on. To determine how safe or how far you can drive with the TPMS light on, you must find out why the tire pressure light is on.
Will a Change in Weather Trigger the Low Tire Pressure Light?
Yes a change in weather over any period of time will trigger the low tire pressure light. Every 10 degree Fahrenheit change in air temperature, tire pressure will change in the same direction by about 1 Psi. Keep in mind that a weather change over the course of a few weeks or months will still have the same impact.
