Register Transmitter (ID)

A: OPERATION

Perform the registration procedure of the transmitter in the following cases:

NOTE:

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 that time, the tire pressure warning light blinks to confirm that the registration has started.)

  1. Air valve (transmitter)
  2. Transmitter registration tool

NOTE:

8) When ID registration is completed, the tire pressure 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)-13, Display Transmitter (ID).>

9) Check the transmitter ID that was registered, then perform a driving test. <Ref. to TPM(diag)-14, Inspection Mode.>

Display Transmitter (ID)

A: OPERATION

For the operation procedure, refer to the "PC application help for Subaru Select Monitor".

Inspection Mode

A: PROCEDURE

Reproduce the malfunction occurrence condition as much as possible. Drive the vehicle at 40 km/h (25 MPH) or faster for at least ten minutes.

Tire Pressure Warning Light / Trouble Indicator Light Illumination Pattern

A: INSPECTION

Subaru Outback. Tire Pressure Monitoring System (Diagnostics)

  1. Ignition switch
  2. OFF
  3. ON
  4. Start
  5. Tire inflation pressure condition
  6. Meet the specification
  7. Less than standard value (For the pressure warning level, refer to "CURRENT DATA".) <Ref. to TPM(diag)-11, LIST, Read Current Data.>
  8. Tire inflation pressure warning light (pressure condition)
  9. Light OFF
  10. Light ON
  11. System status
  12. Normal
  13. Malfunction
  14. Tire inflation pressure warning light (system condition)
  15. Light OFF
  16. Blink
  17. 1 second
  18. Blinks 25 times
  19. 2 seconds

1) When the tire pressure warning light does not illuminate in accordance with this illumination pattern, there must be an electrical malfunction.

2) If the tire pressure warning light does not go off, check the TPMS & keyless entry control module/warning light circuit and the combination meter circuit. <Ref. to TPM(diag)-17, TIRE PRESSURE WARNING LIGHT DOES NOT COME OFF, Tire Pressure Warning Light / Trouble Indicator Light Illumination Pattern.>

NOTE: If the problem is fixed while driving at approximately 40 km/h (25 MPH) after the tire pressure warning light blinks/lights, the warning light goes out and the tire pressure monitor system operates normally. (If there is a decrease in tire pressure, or a malfunction of the system, the malfunction history is displayed.)

B: TIRE PRESSURE WARNING LIGHT DOES NOT COME ON DETECTING CONDITION:

Defective combination meter

TROUBLE SYMPTOM:

When the ignition switch is turned to ON, the tire pressure warning light does not turn on (for approx. 2 seconds).
