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) Connect the Subaru Select Monitor to data link
connector.
(1) Data link connector is located in the lower
portion of instrument panel (on the driver's
side).
(2) Connect the diagnosis cable to data link
connector.
CAUTION:
Do not connect the scan tools except for Suba-
ru Select Monitor.
5) Turn the ignition switch to ON (engine OFF) and
turn the Subaru Select Monitor switch to ON.
6) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.

•For details concerning operation procedure, re-
fer to the “SUBARU SELECT MONITOR OPERA-
TION MANUAL”.
•For details concerning DTCs, refer to List of Di-
agnostic Trouble Code (DTC).
•Display all the DTCs detected.
•If a particular DTC is not properly stored in mem-
ory (due to a drop in occupant detection control
module power supply, etc.) when a problem oc-
curs, the DTC which is suffixed with a question
mark appears on the Subaru Select Monitor dis-
play. This shows it may be an unreliable reading.
