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.
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).
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor to data
link connector.
3) Turn the ignition switch to ON and Subaru
Select Monitor to ON.
NOTE:If the communication function of the Subaru Se-
lect Monitor cannot be executed normally,
check the communication circuit.

•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.

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.

Inflation pressure of each tire reduces under specifications (188 kPs (1.9 kgf/cm2, 27.3 psi) or less).
TROUBLE SYMPTOM:
Tire pressure warning light illuminates.
CAUTION:
When driving vehicle to perform driving test, there should be always 2 persons (driver and checker)
to check.
Step Check Yes No
1CHECK THE TIRES.
Lift-up the vehicle and check for damage in the
tires.
Are there cracks or damage? Replace the tire.
Go to step 2.
2CHECK THE TIRES.
Check the tire air pressure.
Is the tire pressure in the spec-
ifications?
Go to step 3.Adjust the air pres-
sure.
3CHECK THE TRANSMITTER
Drive the vehicle at a speed more than 40 km/h
(25 MPH) and compare the data from the
transmitter on the four wheels.
Is there a transmitter with dif-
ferent data?
