Procedure.>
Step Check Yes No
1 CHECK OUTPUT SIGNAL FROM ECM.
1) Turn the ignition switch to OFF.
2) Connect the test mode connector.
3) Turn the ignition switch to ON.
4) While operating the radiator fan relay, mea-
sure voltage between ECM and chassis ground.

OTE:
Radiator fan relay operation can be executed
using Subaru Select Monitor. For procedure,
refer to “Compulsory Valve Operation Check
Mode”.

2 CHECK SHORT CIRCUIT IN RADIATOR FAN
RELAY CONTROL CIRCUIT.
1) Turn the ignition switch to OFF.
2) Remove the main fan relay, sub fan relay
and fan mode relay.
3) Disconnect the test mode connectors
4) Turn the ignition switch to ON.
5) Measure the voltage between ECM and
chassis ground.

(B135) No. 24 (+) — Chassis ground (
−):
(B135) No. 25 (+) — Chassis ground (

3 CHECK FAN RELAY.
1) Turn the ignition switch to OFF.
2) Remove the fan relay.
3) Measure the resistance between fan relay
terminals.

C: INSPECTION
Repair or replace any defective hoses, pipes,
clamps, and washers found from the inspection be-
low.
1) Check for ATF leaks in joints between the trans-
mission, radiator, pipes, and hoses.
2) Check for deformed clamps.
3) Lightly bend the hose and check for cracks in the
surface and other damage.
4) Pinch the hose with your fingers and check for
poor elasticity. Also check for poor elasticity in the
parts where the clamp was installed by pressing
with your fingernail.
5) Check for peeling, cracks, and deformation at
the tip of the hose.
