Inspection 3: Warning Lamp Flashes When Ignition Switch Is Turned OnEES001IJ
NOTE:
If warning lamp flashes as shown, the system is normal.
Flash Mode A
This mode shows transmitter status is OFF-mode.
Carry out transmitter wake up operation. Refer to WT-18,
"Transmitter Wake Up Operation" .
DIAGNOSTIC PROCEDURE
1. CHECK CONNECTOR
1. Turn ignition switch OFF.
2. Disconnect BCM harness connectors M18 and M20.
3. Check terminals for damage or loose connections.
Inspection results OK?
OK >> GO TO 2.
NG >> Repair or replace damaged parts.
2. CHECK TIRE PRESSURE WARNING CHECK CONNECTOR CIRCUIT
Check continuity between BCM connector M18 terminal 15 and tire pressure warning check connector M123
terminal 1.
OK or NG
OK >> Replace BCM. Refer to BCS-20, "BCM" .
NG >> Repair or replace harness connector.

Inspection 5: “TIRE PRESSURE” Information In Display Unit Does Not ExistEES001Q5
DIAGNOSTIC PROCEDURE
1. SELF-DIAGNOSTIC RESULT CHECK
1. With the ignition switch OFF, connect CONSULT-II and CONSULT-II CONVERTER to the data link con- nector, then turn the ignition switch ON.
2. Select “START (NISSAN BASED VHCL) ”.
3. Select "BCM" on “SELECT SYSTEM” screen.
NOTE:
If the BCM is not indicated, refer to GI-40, "
CONSULT-II Data
Link Connector (DLC) Circuit" .
4. Select "BCM" on "SELECT TEST ITEM" screen, and select "SELF-DIAG RESULTS".
5. Check display contents in self-diagnostic results.
Is "CAN COMM CIRCUIT" displayed in the self-diagnosis display items?
YES >> Malfunction in CAN communication system. Go To LAN-26, "CAN COMMUNICATION" .
NO >> GO TO 2.
2. CHECK DISPLAY UNIT
Perform display unit self-diagnosis. Refer to AV- 11 4 , "
Self-Diagnosis Mode (NAVI)" .
Inspection results OK?

REMOVAL AND INSTALLATION
Revision: November 20092006 QX56
REMOVAL AND INSTALLATIONPFP:00000
Transmitter (Pressure Sensor)EES001IN
REMOVAL
1. Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.
2. Gently bounce tire so that transmitter falls to bottom of tire.
Place wheel and tire assembly on tire changing machine and
break both tire beads. Ensure that the transmitter remains at the
bottom of the tire while breaking the bead.
3. Turn tire so that valve hole is at bottom, and gently bounce the tire to ensure transmitter is near valve hole. Carefully lift tire onto
turntable and position valve hole (and transmitter) 270 degrees
from mounting/dismounting head.
4. Lubricate tire well, and remove top side of tire. Reach inside the tire and remove the transmitter.
5. Remove the second side of the tire as normal.
INSTALLATION
1. Place first side of tire onto rim.
2. Mount transmitter on rim and tighten nut to specification.

3. Place wheel on turntable of tire machine. Ensure that transmitter
is 270 degrees from mounting/dismounting head.
NOTE:
Do not touch transmitter with mounting head.
4. Lubricate tire well, and install second side of tire as normal. Ensure that tire does not rotate relative to rim.
5. Inflate tire and balance the wheel and tire assembly. Refer to WT-6, "
Wheel Balance Adjustment" .
6. Install Wheel and tire assembly in appropriate wheel position on vehicle.
NOTE:
If replacing the transmitter, then transmitter wake up operation must be performed. Refer to WT-18,
"Transmitter Wake Up Operation" .
7. Adjust neutral position of steering angle sensor. Refer to BRC-62, "
Adjustment of Steering Angle Sensor
Neutral Position" .
