A: INSPECTION
*1 If the tires or wheels are wider than standard, the load to the power steering system is increased. Accordingly, in a condition,
for example before fluid warms-up, relief valve may work before reaching maximum turning angle. In this case, steering effort
may be heavy. When the measured hydraulic pressure is normal, there is no abnormal thing. *2 In cold weather, flow resistance will increase due to the cold hydraulic fluid, and steering effort will be heavier. After warming-up en-
gine, turn the steering wheel from stop to stop several times to warm-up fluid. If steering effort reduces normally, function is normal. *3 I n c o l d w e a t h e r o r w i t h i n s u f f i c i e n t w a r m – u p o f t h e e n g i n e , s t e e r i n g e f f o r t m a y b e h e a v y d u e t o e x c e s s i v e d r o p o f i d l e r p m w h en

General Description
TIRE PRESSURE MONITORING SYSTEM (DIAGNOSTICS)
2. General Description
A: CAUTION
1. SRS AIRBAG SYSTEM
Airbag system wiring harness is routed near the
TPM control module.
CAUTION:
•Wiring harnesses of all airbag system are yel-
low. Do not use the electrical test equipment on
these circuits.
•Be careful not to damage the airbag system
wiring harness when servicing the tire pressure
monitoring control module.
2. TIRE PRESSURE MONITORING CON-
TROL MODULE
•If the alteration of tire rotation, the installation po-
sition or the replacement of transmitter is per-
formed, ID registration for the transmitter is
required.
Monitor.>
•When adjusting tire pressure indoors in winter,
there is a big temperature difference between the
indoor facilities and outside. Once the car is outside
where the temperature is lower, the air pressure in
the tires will drop, causing the tire pressure warning
light to come on, even if the pressure in the tires
was adjusted to standard values indoors. To avoid
this, it is necessary to adjust the tire pressure to the
high side in consideration of the difference in tem-
perature between inside and outside.
B: INSPECTION
Before performing diagnosis, check the following
item which might affect the quality of the tire pres-
sure monitoring system.
1. TIRE
•Inspect that the tire pressure is within the speci-
fication while the tire is cool. (Refer to Tire Caution
Label.)
•Check the tires for damage or the insertion of for-
eign matters.
2. BATTERY
Check that amount of battery fluid, gravity and volt-
age are within the specifications.
Standard voltage: 12 V or more
Specific gravity: 1.260 or more

4. REGISTER TRANSMITTER ID
Perform the procedures below to register the trans-
mitter.
•Transmitter replaced.
•Switched the position of the transmitter (rotated
tires)
•Replaced the tire pressure monitoring control
module.
NOTE:
•If registration of the transmitter ID is not possible
after 2 attempts, replace the tire pressure monitor-
ing control module.
REMOVAL, Tire Pressure Monitoring System.>
•If the ignition switch and Subaru Select Monitor
power are turned OFF while registering the trans-
mitter, or if registration is not possible for more than
5 minutes, the registration mode is cancelled.
•When rotating tires, there is no affect on the per-
formance or functions of the tire pressure monitor-
ing control module even if the transmitter (ID) is not
registered, however, the tire position displayed on
the Subaru Select Monitor will be incorrect.
1) Adjust all tire pressures to the specifications.
NOTE:
Refer to the tire caution label on the driver's side
door for the correct tire pressure.
