Steps to Reset the Infiniti Tire Pressure Light
Open the driver side door and locate the tire pressure sticker on the door panel.
To initiate the TPMS reset process, it’s essential to first inflate tires to the exact recommended air pressure stated on the sticker.
Drive your Infiniti for a minimum of 15 minutes at speeds exceeding 25 mph and the tire light will reset as you drive.
The TPMS Reset Procedure Didn't Work, Now What?
Inspect for leaks by spraying soapy water on the tire tread, on the tire beads, and valve stems after inflating to locate any air leaks.
Disconnect the negative battery terminal for a few seconds to reset the Infiniti computer system, potentially clearing TPMS faults.
Deflate each tire by around 10 psi, then reinflate to recommended pressure; drive for at least 10 minutes at 20+ mph and then follow TPMS reset procedure.
Use a TPMS diagnostic tool to scan sensors and identify any malfunctioning units, which is often the cause of warning light.
How Does the Infiniti Tire Pressure Monitoring System Work?
Infiniti vehicles are equipped with a direct tire pressure monitoring system (TPMS) that utilizes tire sensors mounted inside each wheel on the base of each valve stem. These sensors continuously monitor the air pressure within the tires and wirelessly transmit the readings to a central TPMS receiver module which relays them to the Infiniti’s on board computer system. It’s noteworthy that Infiniti vehicles commonly use Shrader brand sensors, which are compatible with the system for monitoring tire pressure.
The TPMS system displays the individual real time tire pressures on the dash, and if any tire’s pressure drops significantly below the recommended level, the TPMS warning light illuminates to alert the driver of low tire pressures. Additionally, the system includes a TPMS interface plug, essential for diagnostics and resetting the TPMS warnings through a straightforward process.
What Causes the Infiniti TPMS Light to Turn On?
The primary cause of the TPMS light illuminating on an Infiniti is one or more tires with low tire pressure, typically 10%-25% or more under the correct pressure listed in the owner’s manual.
However, other potential issues like faulty TPMS sensors, dead sensor batteries, or problems with the TPMS control module itself can also trigger the warning light.
Where is the Infiniti TPMS Reset Button?
Infiniti vehicles tire pressure monitoring systems do not have dedicated tire pressure reset buttons.
Why is My Tire Pressure Light Blinking on My Infiniti?
If the TPMS light is blinking or flashing slowly on your Infiniti, it indicates a fault or malfunction with the tire pressure monitoring system itself rather than just low tire pressure.
Common causes include a failed TPMS sensor, radio interference from other electronic devices, or the need to relearn/reprogram the sensors after tire rotations or replacements. A solid TPMS light means low pressure, while blinking signals an issue that requires diagnosis with a TPMS diagnostic tool or tire shop / dealer.
What Do I Do If My Tire Light is Flashing?
The best way to deal with a flashing or blinking tire pressure light is to use a TPMS diagnostic tool to check the health of each tire pressure sensor.
Why is My Tire Pressure Light on When My Tires Are Fine?
Even with the correct tire pressures, the Infiniti TPMS light can still illuminate due to other factors like faulty tire sensors, dead sensor batteries, or issues with the TPMS control module. Extreme temperature changes can also temporarily affect pressures enough to trigger the light. If all four tires are properly inflated but the warning remains on, the next step is diagnosing the system for a potential component failure using an OBD-II scan tool.
Will the Infiniti Spare Tire Set Off the Low Tire Light?
Infiniti vehicles spare tires do not have TPMS sensors within them. Driving with the spare tire mounted to your car will cause the TPMS warning light to illuminate.
When Do My TPMS Sensors Need to Be Replaced?
Infiniti tire sensors typically last approximately 5-10 years. A TPMS sensor will need to be replaced with new sensors when the batteries are low or dead.
If I Replace One TPMS Sensors Should I Replace All of Them?
Replacing just one faulty TPMS sensor on your Infiniti is possible, but not recommended. TPMS sensor batteries typically last 5-7 years, so if one is failing, the others are likely near the end of their life too. Having mismatched aged sensors can cause issues. For proper functionality and consistent monitoring, it’s best to replace all four TPMS sensors at the same time as a complete set, unless your remaining sensors are very new. The higher upfront cost avoids more frequent replacements down the line.
How Do I Reprogram the TPMS Sensors on My Infiniti?
To reprogram and relearn new TPMS sensors on an Infiniti after replacing sensors, you’ll need to initiate a sensor relearn process. This is done by putting the TPMS system into a learn mode using a dedicated TPMS scan tool. The TPMS tool allows you to program the unique IDs of the new sensors into the Infiniti’s TPMS receiver module. Additionally, the TPMS relearn process is a necessary step after installing new sensors to ensure the system accurately recognizes each sensor.
Once programmed, connect to the vehicle’s diagnostic system using the OBD port to facilitate the TPMS reprogramming procedure. Install each new sensor onto the corresponding wheel and tire location. The relearn mode then enables the TPMS module to detect, identify, and store the IDs of the newly installed tire pressure sensors with their proper wheel positions. This crucial step ensures the system can accurately monitor and display the pressure readings from each specific tire location.
Can I Disable My Infiniti's Tire Pressure Monitoring System?
No, you cannot permanently disable an Infiniti TPM system. Infiniti does not recommend disabling its TPMS, as it is a federally-mandated safety system for monitoring proper tire inflation and preventing blowouts. Removing all four tire pressure sensors will result in a TPMS malfunction (flashing tire light) and then a solid light on the dashboard.
