2. General Description
A: CAUTION
1. SUPPLEMENTAL RESTRAINT SYSTEM
"AIRBAG"
Airbag system wiring harness is routed near the
TPM control module.
CAUTION:
• All airbag system wiring harnesses 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 tire rotation or changes in install locations, or
replacement of the transmitter is performed, ID reg-
istration for the transmitter is required. <Ref. to
TPM(diag)-9, REGISTER TRANSMITTER ID, OP-
ERATION, Subaru Select 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: Above 1.260
