LOW TIRE PRESSURE WARNING SYSTEMPFP:40300
System ComponentsEES002FF
System DescriptionEES002FG
BODY CONTROL MODULE (BCM)
The BCM is shown with the glove box removed. The BCM reads the
air pressure signal received by the remote keyless entry receiver,
and controls the low tire pressure warning lamp as shown below. It
also has a self-diagnosis function to detect a system malfunction.

LOW TIRE PRESSURE WARNING SYSTEM
Revision: June 20062007 Versa
TRANSMITTER
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 glove box
removed. The remote keyless entry receiver receives the air pres-
sure 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.

TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMS
Revision: June 20062007 Versa
TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMSPFP:00000
Data From Transmitter Not Being ReceivedEES002F5
MALFUNCTION CODE NO. 21, 22, 23 OR 24 (DTC C1708, C1709, C1710 OR C1711)
1. CHECK BCM
Drive for several minutes. Check all tire pressures with CONSULT-II.
Are all tire pressures displayed as 0 kPa?
YES >> GO TO 2.
NO >> GO TO 3.
2. CHECK REMOTE KEYLESS ENTRY RECEIVER CONNECTOR
Check remote keyless entry receiver connector for damage or loose connections.
OK or NG
OK >> Replace BCM, then GO TO 3. Refer to BCS-25, "Removal and Installation of BCM" .
NG >> Repair or replace remote keyless entry receiver connector.
3. PERFORM ID REGISTRATION
Carry out ID registration of all transmitters. Refer to WT-11, "
ID Registration Procedure" .
Is there a tire that cannot register ID?
YES >> Replace transmitter of the tire, then GO TO 5. Refer to WT-27, "Transmitter (Pressure Sensor)" .
NO >> GO TO 4.
4. DRIVE VEHICLE
1. Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.
2. Check all tire pressures with CONSULT-II within 15 minutes after vehicle speed becomes 17 km/h (11
MPH).
Does
“DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?
YES >> Inspection End.
NO >> GO TO 5.
5. ID REGISTRATION AND VEHICLE DRIVING
1. Carry out ID registration of all transmitters. Refer to WT-11, "
ID Registration Procedure" .
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for
10 minutes.
3. Check all tire pressures with CONSULT-II within 5 minutes.
Does
“DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?
YES >> Inspection End.
NO >> GO TO the inspection applicable to DTC.
