Do not connect any scan tools except Subaru
Select Monitor or general scan tool.
8) Turn the ignition switch to ON (engine OFF) and
Subaru Select Monitor switch to ON.
9) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.
10) On the «System Selection Menu» display
screen, select the {Engine} and press the [YES]
key.

“SUBARU SELECT MONITOR OPERATION
MANUAL”.
•For details concerning DTC, refer to “List of Di-
agnostic Trouble Code (DTC)”.

•Release the parking brake.
•The speed difference between front and rear
wheels may light the ABS warning light, but this
indicates no malfunctions. When engine control
diagnosis is finished, perform the ABS memory
clearance procedure of self-diagnosis function.

wheels may light the ABS warning light, but this in-
dicates no malfunctions. When engine control diag-
nosis is finished, perform the ABS memory
clearance procedure of self-diagnosis system.

INDICATOR LIGHT
1) When the ignition switch is turned to ON (engine
OFF), the malfunction indicator light (A) in the com-
bination meter illuminates.
NOTE:
If the engine malfunction indicator light does not il-
luminate, perform diagnostics of malfunction indi-
cator light circuit or the combination meter circuit.
DICATOR LIGHT DOES NOT COME ON, Malfunc-
tion Indicator Light.>
2) After starting the engine, the malfunction indica-
tor light goes out. If it does not go off, either the en-
gine or emission control system has malfunction.
3) Turn the ignition switch to OFF and connect the
test mode connector.
(1) When the ignition switch is turned to ON (en-
gine OFF), the malfunction indicator light illumi-
nates.
(2) After the engine starts, malfunction indicator
light blinks in a cycle of 0.5 Hz.(During diagno-
sis)
(3) Malfunction indicator light blinks at a cycle of
3 Hz after diagnosis if there is no trouble. Mal-
function indicator light illuminates if faulty.

1) Turn the ignition switch to ON.
2) Measure the voltage between ECM con-
nector and chassis ground.
Connector & terminal
(B136) No. 11 (+) — Chassis ground (–):
Is the voltage less than 1 V? Go to step 4.Go to step 2.
2CHECK POOR CONTACT.
Check for poor connection by shaking or pull-
ing ECM connector and harness.
Does the malfunction indicator
light illuminate?
Repair poor con-
tact in ECM con-
nector.
