Basic Diagnostic Procedure
TIRE PRESSURE MONITORING SYSTEM (DIAGNOSTICS)
1. Basic Diagnostic Procedure
A: PROCEDURE
CAUTION:
Remove foreign matter (dust, water, oil etc.) from the tire pressure monitoring control module con-
nector when removing or installing.
NOTE:
To check harness for broken wires or short circuits, shake trouble spot or connector.
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Check with the user regarding when the
warning light lit or started blinking.
2) Before performing diagnostics, check the
components which might mal-affect tire pres-
sure monitor system. INSPECTION, General Description.>
Is the component that might
affect the tire pressure monitor
system normal?
Go to step 2.Repair or replace
each component.
2CHECK DIAGNOSTIC TROUBLE CODE
(DTC).

lect Monitor cannot be executed normally,
check the communication circuit. TPM(diag)-11, COMMUNICATION FOR INI-
TIALIZING IMPOSSIBLE, INSPECTION, Sub-
aru Select Monitor.>

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. TRANSMITTER ID, OPERATION, 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: 1.260 or more
