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 HARNESS.
1) Disconnect the tire pressure monitoring
control module connector.
2) 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.
3 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 mea-
sure the voltage.

4 CHECK COMBINATION METER.
1) Short the combination meter connector
(i11) No. 6 to chassis ground.
2) Turn the ignition switch to ON.
5 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.
