1A-26 Engine General Information and Diagnosis:

Malfunction Indicator Lamp Does Not Come ON with Ignition Switch ON and Engine Stop (but
Engine Can Be Started)

S5JB0E1104011

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 signal of malfunction indicator lamp (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.

Troubleshooting

NOTE

• Before performed troubleshooting, be sure to read the “Precautions of ECM Circuit Inspection in

related manual”.

• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the

special tool to ECM and/or the ECM connectors referring to “Inspection of ECM and Its Circuits”.

Step

Action

Yes

No

1

MIL power supply check
1) Turn ignition switch to ON position.

Do other warning lights come ON?

Go to Step 2.

Go to Step 5.

2

DTC check
1) Connect scan tool to DLC with ignition switch turned

OFF.

2) Turn ON ignition switch and check DTC.

Is there DTC(s) P1674 and/or P1685?

Go to applicable DTC
diag. flow.

Go to Step 3.

3

DTC check in ABS / ESP

® control module assembly

1) Check DTC in ABS / ESP

® control module assembly.

Is there DTC(s) U1073 and/or U1100?

Go to applicable DTC
diag. flow.

Go to Step 4.

4

DTC check in BCM
1) Check DTC in BCM.

Is there DTC U1100?

Go to applicable DTC
diag. flow.

Substitute a known-
good combination meter
and recheck. If MIL still
remains OFF, substitute
a known-good ECM and
recheck.

5

CAN communication line circuit check
1) Check CAN communication circuit between combination

meter and ECM, TCM (for A/T model), ABS / ESP

®

control module, 4WD control module (if equipped),
keyless start control module (if equipped) referring to
Step 9 to 15 of “DTC P1674: CAN Communication (Bus

Go to Step 7.

Replace “METER” fuse
and check for short.

7

Combination meter power supply check
1) Remove combination meter referring to “Combination

Meter Removal and Installation in Section 9C in related
manual”.

2) Check for proper connection to combination meter

connector at “G28-13” and “G28-15” terminals.

3) If OK, then turn ignition switch to ON position and

measure voltage between combination meter connector
at “G28-13” terminal and vehicle body ground.

Is it 10 – 14 V?
