Is the ECM connector correctly
connected? Replace the ECM.
<Ref. to
FU(H6DO)-33,
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. <Ref. to
IDI-14, 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
(B136) No. 11 — (i10) No. 16:
Is the resistance less than 1
Ω
?
Go to step
5
. Repair the har-
ness and connec-
tor.
NOTE:
In this case, repair
the following item:
• Open circuit in
harness between
ECM and combi-
nation meter con-
nector
• Poor contact in
coupling connector
5 CHECK POOR CONTACT.
Check poor contact of combination meter con-
nector.
Is there poor contact in combi-
nation meter connector? Repair the poor
contact of combi-
nation meter con-
nector. Go to step 6 .
6 CHECK HARNESS BETWEEN COMBINA-
TION METER AND IGNITION SWITCH CON-
NECTOR.
1) Turn the ignition switch to ON.
2) Measure the voltage between combination
meter connector and chassis ground.
Connector & terminal
(i10) No. 3 (+) — Chassis ground (–):
(i10) No. 4 (+) — Chassis ground (–):
Is the voltage more than 10 V? Replace the com-
bination meter cir-
cuit board. <Ref. to
IDI-14, Combina-
tion Meter.>
Check the follow-
ing item and repair
if necessary.
NOTE:
• Blown out of
fuse (No. 5)
• Open or short
circuit in harness
between fuse (No.
5) and battery ter-
minal
• Poor contact in
ignition switch con-
nector
Step Check Yes No
