Step Check Yes No
1 CHECK OUTPUT SIGNAL FROM ECM.
1) Turn the ignition switch to ON.
2) Measure the voltage between ECM con-
nector and chassis ground.
Connector & terminal
(B134) No. 28 (+) — Chassis ground (
−):Is the voltage less than 1 V? Go to step 4.Go to step 2.
2 CHECK POOR CONTACT.
Check for poor connection when shaking or
pulling ECM connector and harness.Does malfunction indicator
light illuminate?Repair the poor
contact in ECM
connector.Go to step 3.
3 CHECK ECM CONNECTOR.
Check the connection of ECM connector.Is the ECM connector correctly
connected?Replace the ECM.
Engine Control
Module (ECM).>Repair the con-
nection of ECM
connector.
4 CHECK HARNESS BETWEEN COMBINA-
TION METER AND ECM CONNECTOR.
1) Turn the ignition switch to OFF.
2) Remove the combination meter.
3) Disconnect the connector from ECM and
combination meter.
4) Measure the resistance of harness
between ECM and combination meter connec-
tor.
Connector & terminal
(B134) No. 28 — (i12) No. 1:Is the resistance less than 1
Ω?Go to step 5.Repair harness
and connector.

In this case repair
the following:
Open circuit in
harness between
ECM and combi-
nation meter con-
nector
Poor contact in
coupling connector
5 CHECK POOR CONTACT.
Check poor contact in combination meter con-
nector.Is there poor contact in combi-
nation meter connector?Repair poor con-
tact in combination
meter connector.Go to step 6.

2) Measure the voltage between combination
meter connector and chassis ground.
Connector & terminal
(i12) No. 9 (+) — Chassis ground (
−):Is the voltage more than 10 V? Go to step 7.Check the follow-
ing and repair if
necessary.

(No. 5)
If replaced fuse
(No. 5) blows eas-
ily, check the har-
ness for short
circuit of harness
between fuse (No.
5) and ignition
relay connector.
Open or short
circuit in harness
between fuse (No.
5) and battery ter-
minal
Open circuit in
harness between
fuse (No. 5) and
ignition relay con-
nector
Poor contact in
ignition relay con-
nector
Poor contact in
ignition switch con-
nector
7 CHECK BULB.Is the malfunction indicator
light bulb OK?Repair combina-
tion meter connec-
tor.Replace the bulb. Step Check Yes No

1 CHECK SPEEDOMETER AND TACHOME- TER OPERATION IN COMBINATION
METER. Does the speedometer and
tachometer operate normally?
Go to step
2.Repair or replace
the combination
meter.
Meter System.>
2 CHECK INPUT SIGNAL FROM ECM. 1) Turn the ignition switch to ON. (engine
OFF)
2) Measure the voltage between ECM con-
nector and chassis ground.
Connector & terminal (B135) No. 25 (+) — Chassis ground (
−): Is the voltage less than 0.12
V?
Go to step
4.Go to step 3.
3 CHECK INPUT SIGNAL FOR ECM (WITH SUBARU SELECT MONITOR).
Read the data of fuel level sensor signal using
Subaru Select Monitor.

and connector?
Repair the poor
contact in ECM
connector.Even if the mal-
function indicator
light illuminates,
the circuit has
returned to a nor-
mal condition at
this time. A tempo-
rary poor contact
of the connector
may be the cause.
NOTE:
In this case repair
the following:
Poor contact in
combination meter
connector
Poor contact in
ECM connector.
Poor contact in
coupling connector
