ENGINE (DIAGNOSTICS)
2
CHECK HARNESS BETWEEN COMBINA-
TION METER AND MULTI-SELECT SWITCH
CONNECTOR.
1) Disconnect the connector from multi-select
switch.
2) Measure the resistance of harness between
combination meter and multi-select switch con-
nector.
Connector & terminal
(i10) No. 33 — (R33) No. 8:
(i10) No. 35 — (R33) No. 5:
Is the resistance less than 1 Ω? Go to step
3.
Repair the harness
and connector.
NOTE:
In this case, repair
the following item:
• Open circuit in
harness between
combination meter
and
multi-select
switch connector
• Poor contact of
coupling connector
3
CHECK HARNESS BETWEEN COMBINA-
TION METER AND MULTI-SELECT SWITCH
CONNECTOR.
Measure the resistance between multi-select
switch connector and chassis ground.
Connector & terminal
(R33) No. 8 — Chassis ground:
(R33) No. 5 — Chassis ground:
Is the resistance 1 MΩ or
more?
Repair the poor
contact of multi-
select switch con-
nector. Replace
the multi-select
switch if defective.
<Ref. to FU(STI)-
58, SI-DRIVE
(SUBARU Intelli-
gent Drive) Selec-
tor.>
Repair the ground
short circuit in har-
ness between
combination meter
and multi-select
switch connector.
4
CHECK HARNESS BETWEEN COMBINA-
TION METER AND CHASSIS GROUND.
Measure the resistance of harness between
combination meter and chassis ground.
Connector & terminal
(i10) No. 21 — Chassis ground:
(i10) No. 22 — Chassis ground:
Is the resistance less than 5 Ω? Go to step
5.
Repair the harness
and connector.
NOTE:
In this case, repair
the following item:
• Open circuit in
harness between
combination meter
and
chassis
ground
• Poor contact of
coupling connector
5
RECHECK FAULT.
1) Connect all connectors.
2) Switch SI-DRIVE modes.
Is there any fault?
Repair the poor
contact of combi-
nation meter con-
nector. Replace
the combination
meter if defective.
<Ref. to IDI-16,
Combination
Meter.>
The circuit has
returned to a nor-
mal condition at
this time. Repro-
duce the failure,
and then perform
the diagnosis
again.
NOTE:
In this case, tem-
porary poor con-
tact of connector,
temporary open or
short circuit of har-
ness may be the
cause.
