TIRE PRESSURE MONITORING SYSTEM (DIAGNOSTICS)
Step
1 CHECK IGNITION SWITCH.
2 CHECK BATTERY.
3 CHECK BATTERY TERMINAL.
4 CHECK SUBARU SELECT MONITOR COM-
MUNICATION.
1) Turn the ignition switch to ON.
2) Using the Subaru Select Monitor, check
whether communication to other systems can
be performed normally.
5 CHECK SUBARU SELECT MONITOR COM-
MUNICATION.
1) Turn the ignition switch to OFF.
2) Disconnect the tire pressure monitoring
control module connector.
3) Turn the ignition switch to ON.
4) Check whether communication to other
systems can be executed normally.
6 CHECK HARNESS CONNECTOR BETWEEN
EACH CONTROL MODULE AND DATA LINK
CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the tire pressure monitoring
control module.
3) Measure the resistance between data link
connector and chassis ground.
Connector & terminal
(B40) No. 10 — Chassis ground:
7 CHECK THE TIRE PRESSURE MONITORING
CONTROL MODULE OUTPUT SIGNAL.
1) Turn the ignition switch to ON.
2) Measure the voltage between tire pressure
monitoring control module and chassis ground.
Connector & terminal
(B40) No. 10 (+) — Chassis ground (–):
8 CHECK HARNESS CONNECTOR BETWEEN
TIRE PRESSURE MONITORING CONTROL
MODULE AND DATA LINK CONNECTOR.
Measure the resistance between tire pressure
monitoring control module and data link con-
nector.
Connector & terminal
(R211) No. 1 — (B40) No. 10:
9 CHECK TIRE PRESSURE MONITORING
CONTROL MODULE CONNECTOR.
Turn the ignition switch to OFF.
Subaru Select Monitor
Check
Is the ignition switch ON?
Is the voltage 11 V or more?
Is there poor contact at the bat-
tery terminal?
