51 w w w . M o d e r n T i r e D e a l e r . c o m outside temperature. If the outside temperature is low, the air inside the tire may cool, causing a lower tire inflation pressure. is may cause the low tire pressure warning light to illuminate. When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the warning light in the instrument cluster comes on. If the system detects that air pressure is less than 27 psi (190 kPa), it will also sound a buzzer for 10 seconds and a "FLAT TIRE" or "CHECK TIRE PRESSURE" warning message will appear in instrument cluster display (if equipped). e instrument cluster display unit displays the air pressure of each tire (except the spare tire). Aer the ignition switch is turned on, the pressure values will not be displayed until the data of each wheel is received. NOTE: Pressure indication in "** psi" on the screen indicates that the pressure is being measured. Aer a few driving trips, the pressure for all four tires will be displayed. e order of tire pressure figures displayed does not correspond with the actual order of tire position. When the tire pressure warning light comes on, immediately check the air pressure of all tires and adjust to the specified pressure. Make sure the warning light goes off. e warning light does not automatically turn off when the tire pressure is adjusted. Aer the tire is inflated to the recommended pressure, the vehicle must be driven at speeds above 25 mph (40 km/h) to activate the TPMS and turn off the low tire pressure warning light. If the warning light stays on or flashes, there is a malfunction in the TPMS. See the appropriate manufacturer service information. TPMS RESET PROCEDURES NOTE: When a spare tire is mounted, or a wheel, tire pressure sensor or BCM is replaced, the tire pressure sensor must be registered. e low tire pressure warning light does not automatically turn off when the tire pressure is adjusted. Aer the tire is inflated to the recommended pressure, the vehicle must be driven at speeds above 25 mph (40 km/h) to activate the TPMS and turn off the low tire pressure warning light. TIRE PRESSURE SENSOR REGISTRATION NOTE: If the tire pressure sensor was replaced, the new sensor will be in an "asleep" mode. To wake up the sensor, see "Transmitter wake-up operation." NOTE: To register a new tire pressure sensor, a Nissan Signal Tech II scan tool or CONSULT scan tool can be used. A transmitter activation tool (J-45295) is used in the wake-up procedure and can aid in the registration procedure if using the CONSULT tool system. Sensor registration and wake-up methods in this article reference CONSULT type scan tool procedures. NOTE: If a CONSULT-II is used without also using the CON- SULT-II CONVERTER, a malfunction might be detected during self-diagnosis, depending on which control unit carries-out CAN communication.
