This TSB applies to all Nissan vehicles equipped with a tire pressure monitoring system (TPMS), where the TPMS warning light is illuminated steady or flashing.
Turn the ignition to OFF and then ON (engine not required to be running).
If the TPMS warning light is illuminated steady, the TPMS is operating normally and has detected low tire pressure in one or more of the tires. Some 2011 models will display an alert in the vehicle information display near the speedometer. The alert will read “Check Tire Pressure” or similar message, and will accompany the TPMS light.
If the TPMS warning light is flashing for approximately one minute, there is a TPMS system malfunction. Do not go to Step 2. Instead, check the DTC and refer to the service manual for repair instructions.
Leave the ignition in the ON position (engine not required to be running) and set tire pressures to the recommended pressure. Leaving the ignition in the ON position may allow the TPMS to detect the corrected tire pressure more quickly in 2009 and newer models, without having to drive the vehicle.
