Nissan Rogue Service Manual: System

System Description

When the vehicle has reached a speed of 40 km/h (25 MPH) or greater, the BCM receives a signal transmitted from the tire pressure sensors installed in each wheel. If the BCM detects low inflation pressure or a system malfunction, it sends a signal to the combination meter via CAN communication to illuminate the low tire pressure warning lamp.In addition, a warning message will be displayed in the vehicle information display. Refer to the Owner’s Manual for additional information.

The tire pressure monitoring system (TPMS) has Easy fill tire alert function to aid in tire inflation. Refer to WT- 9, "Easy Fill Tire Alert Function".

Easy Fill Tire Alert Function

• This function operates only when the select lever position is in P-range with the power switch ON or with the vehicle set to READY.

  NOTE: The easy fill tire alert function is recommended to use with the power switch ON.

  NOTE: When beginning tire inflation, it takes a few seconds for the Easy fill tire alert to function. If there is no response for approximately 15 seconds or more, cancel the Easy fill tire alert function and move the vehicle approximately 1 m (3.2 ft) backward or forward to try again.

•  The Easy fill tire alert function operates only when the select lever position is in P-range with the ignition switch ON.
•  This function informs the driver with a visual and audible indication that the recommended COLD tire pressure has been reached.
•  The hazard warning lamps blink when the recommended COLD tire pressure has been reached. After the recommended COLD tire pressure has been reached, the horn sounds once and the hazard warning lamps stop blinking.
•  If the tire pressure value is equal to or greater than 30 kPa (0.31 kg/cm2, 4 psi) more than the recommended COLD tire pressure, the hazard warning lamps flash and horn sounds three times.
•  To return the tire to the recommended COLD tire pressure, deflate the tire until the horn sounds once and the hazard warning lamps stop blinking.
