Nissan Xterra. Manual - part 712

WT-10

< SYSTEM DESCRIPTION >

TPMS

A sensor-transmitter integrated with a valve is installed in each

wheel, and transmits a detected air pressure signal in the form of a

radio wave. The radio signal is received by the remote keyless entry

receiver.

REMOTE KEYLESS ENTRY RECEIVER

The remote keyless entry receiver is shown with the instrument

panel RH removed. The remote keyless entry 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 warn-

ing lamp is activated. A CHECK TIRE PRES 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-33, "Self-

Diagnosis (Without CONSULT)"

. The tire pressure warning check

connector (1) is located behind the lower portion of the instrument

panel LH.
