Nissan Maxima Service and Repair Manual: TPMS
System Diagram
System Description
DESCRIPTION
During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.
The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.
FUNCTION
When the tire pressure monitoring system detects low inflation pressure or an internal malfunction, the low tire pressure warning lamp in the combination meter comes on. The malfunction is indicated by the low tire pressure warning lamp flashing.
BODY CONTROL MODULE (BCM)
The BCM (1) is shown with the combination meter removed. The BCM reads the air pressure signal received by the tire pressure receiver, and controls the low tire pressure warning lamp as shown below. It also has a self-diagnosis function to detect a system malfunction.
TRANSMITTER
A sensor-transmitter integrated with a valve is installed in each wheel. It transmits a detected air pressure signal in the form of a radio wave when the vehicle is moving. The radio signal is received by the tire pressure receiver.
TIRE PRESSURE RECEIVER
The tire pressure receiver (1) is located on the RH side of the steering column, and is shown with the lower instrument panel LH removed. The tire pressure receiver receives the air pressure signal transmitted by the transmitter in each wheel.
COMBINATION METER
The combination meter receives tire pressure status from the BCM using CAN communication. When a low tire pressure condition is sensed by the BCM, the combination meter low tire pressure warning lamp is activated. A CHECK TIRE PRESSURE warning message will also be displayed in the vehicle information display. Refer to the Owner's Manual for additional information.
TIRE PRESSURE WARNING CHECK CONNECTOR
The tire pressure warning check connector can be grounded in order to initiate self-diagnosis without a CONSULT. Refer to WT-44, "Self- Diagnosis (Without CONSULT)". The tire pressure warning check connector (1) is located behind the lower portion of the instrument panel LH, above the hood release handle.
