Tire Pressure Sensor Learn - Suzuki XL7 2007 Service Manual

10D-11 Tire Pressure Monitoring System:
Installation Procedure
1. Clean any dirt or debris from the grommet sealing
areas.
2. Install the grommet on the sensor valve stem.
3. Insert the sensor in the wheel hole with the air
passage facing away from the wheel.
CAUTION
!
Refer to "Fastener Notice: ".
4. Install the sensor nut and position the sensor body
parallel to the inside wheel surface while torquing.
Tightening torque
Tighten the sensor nut to 7 N⋅m (62 lb in).
NOTE
Before installing the tire on the wheel, note
the following items to avoid tire pressure
sensor damage upon tire mounting:
• Position the mounting/dismounting head
180 degrees from the valve stem.
• Position the bead transition area 45
degrees counterclockwise of the valve
stem.
• Using the tire machine, rotate the tire/
wheel assembly clockwise when
transferring the tire bead to the inside of
the wheel rim.
• Repeat items for outer bead.
5. Install the tire on the wheel. Refer to "Tire Mounting
and Dismounting: ".
6. Install the tire/wheel assembly on the vehicle. Refer
to "Tire and Wheel Removal and Installation: ".
7. Lower the vehicle.

Tire Pressure Sensor Learn

Special tool
J-46079 Tire Pressure Monitor Diagnostic Tool
TPM Learn Mode Description
The tire pressure monitor (TPM) system uses the remote
control door lock receiver (RCDLR), exterior lamp
switch, 4 RF transmitting pressure sensors and the serial
data circuit to perform the TPM learn mode functions.
The sensor learn procedure must be performed after
every tire rotation, RCDLR replacement, or sensor
replacement. Once the TPM learn mode has been
enabled, each of the sensor's unique identification (ID)
codes can be learned in to the RCDLR's memory. When
a sensor ID has been learned, the RCDLR sends a serial
data message to the BCM to sound a horn chirp. This
verifies the sensor has transmitted its ID and the RCDLR
has received and learned it. The RCDLR must learn the
sensor Ids in the proper order to determine correct
sensor location. The first learned ID is assigned to the
left front location, the second to right front, the third to
right rear and the fourth to left rear.
Sensor Functions using pressure increase/decrease
method
Each sensor takes a pressure measurement sample
once every 30 seconds while in stationary mode. If the
tire pressure increases, or decreases by more than 1.2
psi from the last transmitted pressure, another
measurement will occur immediately to verify the change
in pressure. If a pressure change has indeed occurred,
the sensor transmits in re-measure mode. When the
RCDLR receives a re-measure mode transmission while
in TPM learn mode, it will assign that sensor's ID to the
location on the vehicle relative to the order in which it
was learned.
Sensor functions using J-46079
Each sensor has an internal low frequency (LF) coil.
When the J-46079 is used in activate mode it produces
an LF transmission that activates the sensor. The sensor
responds to a LF activation by transmitting in learn
mode. When the RCDLR receives a learn mode
transmission while in TPM learn mode, it will assign that
sensor's ID to the location on the vehicle relative to the
order in which it was learned.
TPM Learn Mode Cancellation
The learn mode will cancel if more than 2 minutes have
passed and no sensor have been learned, or if more
than 5 minutes has passed for the entire procedure. If
the learn mode is canceled before any Ids are learned,
the RCDLR will remember all previously stored Ids and
their locations. As soon as the RCDLR learns the first ID,
all other Ids are erased from the RCDLR's memory.
