4. REGISTER TRANSMITTER ID

Perform the registration procedure of the transmit-

ter in the following cases:

• Transmitter replaced.

• TPMS & keyless entry control module replaced.
NOTE:

• If registration of the transmitter ID is not possible

after 2 attempts, replace TPMS & keyless entry

control module. <Ref. to WT-8, TPMS & KEYLESS

ENTRY CONTROL MODULE, REMOVAL, Tire

Pressure Monitoring System.> <Ref. to WT-9,

TPMS & KEYLESS ENTRY CONTROL MODULE,

INSTALLATION, Tire Pressure Monitoring Sys-

tem.>

• During the registration, turn the ignition switch to

OFF and end the Subaru Select Monitor. Or if the

registration is not performed for 5 minutes or more,

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.

2) Connect Subaru Select Monitor and select the

{Each System Check} on the «Main Menu».

3) On «System Selection Menu» display, select

{Tire pressure monitor}.

4) After the {Tire pressure monitor} is displayed,

select [OK].

5) On «Tire pressure monitor diagnosis» display,

select {Transmitter ID regist confirm}.

6) {ID registration mode When execute Registered

ID is deleted. Continue?} is displayed, select [OK].

7) Contact the transmitter registration tool to the

side wall area near the air valve on the front left tire,

and press the switch. The transmitter ID is sent to

the TPMS & keyless entry control module. (At this

time, the tire pressure warning light blinks to con-

firm that the registration has started.)

NOTE:

• The registration order of transmitter ID is not

specified.

• The transmitter registration tool is used by touch-

ing the side wall area near the transmitter.

• If registration procedure stop in the halfway

(turning ignition switch to OFF, wrong registration

order, etc), proceed from step 5).

8) When ID registration is completed, the tire pres-

sure warning light remains lit for approximately 2

seconds, to end the registration. Switch to the

screen displaying the transmitter ID on the Subaru

Select Monitor display. <Ref. to TPM(diag)-9, DIS-

PLAY TRANSMITTER (ID), OPERATION, Subaru

Select Monitor.>

9) Check the transmitter ID that was registered,

then perform a driving test. <Ref. to TPM(diag)-13,

PROCEDURE, Inspection Mode.>

5. DISPLAY TRANSMITTER (ID)

1) On «Main Menu» display, select {Each System

Check}.

2) On «System Selection Menu» display, select

{Tire pressure monitor}.

3) After the {Tire pressure monitor} is displayed,

select [OK].

4) On «Tire pressure monitor diagnosis» display,

select {Transmitter ID regist confirm}.

5) Select the {Transmitter ID monitor} and then se-

lect [OK] to display the transmitter ID.
