3CHECK ECM CONNECTOR.
Check the connection of ECM connector.
Is the ECM connector correctly
connected?
Replace the ECM.
FU(H6DO)-32,
Engine Control
Module (ECM).>
Repair the con-
nection of ECM
connector.
4CHECK HARNESS BETWEEN COMBINA-
TION METER AND ECM CONNECTOR.
1) Turn the ignition switch to OFF.
2) Remove the combination meter.
IDI-11, 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 — (i11) No. 11:
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
of harness be-
tween ECM and
combination
meter connec-
tor
•Poor contact
of coupling con-
nector
5CHECK 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.
6CHECK 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
board.
IDI-11, Combina-
tion Meter.>
Check the follow-
ing item and repair
if necessary.
NOTE:
•Blown out of
fuse (No. 5)
•Open or short
circuit of har-
ness between
fuse (No. 5) and
battery terminal
•Poor contact
of ignition
switch connec-
tor
