Tire Pressure Warning Light / Trouble Indicator Light Illumination Pattern
TIRE PRESSURE MONITORING SYSTEM (DIAGNOSTICS)
Step
1 CHECK DIAGNOSTIC TROUBLE CODE
(DTC).
Connect the Subaru Select Monitor, and read
the Diagnostic Trouble Code. <Ref. to
TPM(diag)-8, READ DIAGNOSTIC TROUBLE
CODE (DTC), OPERATION, Subaru Select
Monitor.>
2 CHECK DATA OUTPUT.
1) Select data display of the tire pressure
monitoring.
2) Check that the warning light output is ON
for approximately 2 seconds immediately after
turning the ignition switch to ON.
3 CHECK HARNESS.
1) Disconnect the tire pressure monitoring
control module connector.
2) Use a lead wire to short the terminal No. 2
of the tire pressure monitoring control module
harness connector (R211) with the chassis
ground, and turn the ignition switch to ON.
4 CHECK HARNESS.
1) Connect the tester to the terminal No. 2 of
the tire pressure monitoring control module
connector (R211)
2) Turn the ignition switch to ON and measure
the voltage between the tire pressure monitor-
ing control module connector and chassis
ground.
Connector & terminal
(R211) No. 2 (+) — Chassis ground (–):
5 CHECK COMBINATION METER.
1) Short the combination meter connector
(i11) No. 6 to chassis ground.
2) Turn the ignition switch to ON.
6 CHECK HARNESS.
1) Disconnect the combination meter connec-
tor (i11).
2) Measure the resistance between tire pres-
sure monitoring control module connector (i11)
and chassis ground.
Connector & terminal
(i11) No. 6 — Chassis ground:
Check
Is diagnostics code (DTC) dis-
played?
Is the warning light output ON
for approximately 2 seconds?
Is the tire pressure warning
light lit?
Is the voltage 10 V or more?
Is the tire pressure warning
light lit?
Is resistance less than 1 Ω?
