• Improperly formed or damaged terminals.Check each connector terminal in problem circuits 
carefully to ensure good contact tension by using the 
corresponding mating terminal.
If contact tension is not enough, reform it to increase 
contact tension or replace.
• Poor terminal-to -wire connection.
Check each wire harness in problem circuits for poor 
connection by shaking it by hand lightly. If any 
abnormal condition is found, repair or replace. • Wire insulation which is rubbed through, causing an 
intermittent short as the bare area touches other 
wiring or parts of the vehicle.
• Wiring broken inside the  insulation. This condition 
could cause continuity check to show a good circuit, 
but if only 1 or 2 strands of a multi-strand-type wire 
are intact, resistance could be far too high.
If any abnormality is found, repair or replace.
1. Check contact tension by inserting and removing just once.
2. Check each terminal for bend and proper alignment.

MIL Does Not Come ON with Ignition Switch ON and Engine Stop (but Engine Can Be Started)S7RS0B1104011
Wiring Diagram
Circuit Description
When the ignition switch is turned ON, ECM causes the main relay to turn ON (close the contact point). Then, ECM 
being supplied with the main power, transmits indication ON si gnal of MIL to combination meter in order to turn MIL 
ON. And then, combination meter turns MIL ON. When the engine  starts to run and no malfunction is detected in the 
system, ECM transmits MIL indication  OFF signal to combination meter in order to turn MIL OFF. And then, 
combination meter turns MIL OFF, but if  a malfunction was or is detected, MIL remains ON even when the engine is 
running.

Wire circuit check
1) Disconnect radiator cooling fan control relay No. 2 and 
No. 3 from individual circuit  fuse box No.1 with ignition 
switch turned OFF.
2) Measure resistance between “E23-48” terminal of ECM  connector and vehicle body ground.
Is resistance infinity? Go  to Step 13. “GRN” wire is shorted to 
ground circuit.
13 Wire circuit check
1) Turn ON ignition switch.
2) Measure voltage between “E23-48” terminal of ECM 
connector and vehicle body ground.
Is voltage 0 V? Go  to Step 14. “GRN” wire is shorted to 
power supply circuit.
14 Radiator cooling fan relay No. 2 and No. 3 check
1) Check radiator cooling fan relay No. 2 and No. 3 
referring to “Radiator Coolin g Fan Relay Inspection in 
Section 1F”.
Are relays in good condition? “GRN” wire is open 
circuit.
Replace relay.
15 Radiator cooling fan control No. 2 and No. 3 check
1) Connect connectors to ECM with ignition switch turned 
OFF.
2) Connect radiator cooling fan relay No. 2 to individual  circuit fuse box No.1.
3) Run engine until ECT is over 102.5  °C, 216.5  °F.
4) Measure voltage between vehicle body ground and  “E23-48” terminal of ECM connector.
Is voltage lower than 1.5 V? Intermittent trouble.
Check for intermittent 
refer to “Intermittent and 
Poor Connection 
Inspection in Section 
00”.
If OK, substitute a 
known-good ECM and
