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.

Troubleshooting
NOTE
When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the special
tool to ECM and/or the ECM connectors referri ng to “Inspection of ECM and Its Circuits”.
Malfunction Indicator Lamp Remains ON after Engine StartsS7RS0B1104012
Wiring Diagram and Circuit Description
Refer to “MIL Does Not Come ON wit h Ignition Switch ON and Engine Stop (but Engine Can Be Started)”.
Step
Action YesNo
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 3.
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, P1676, P1678 and/or P1685? 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.
3 CAN communication line circuit check
1) Check CAN communication circuit between combination
meter and ECM, TCM (A/T model) referring to Step 3 of
“DTC P1674: CAN Communication (Bus Off Error)”
Is circuit in good condition? Go to Step 4.
Repair or replace.
4 “METER” fuse check
1) Turn ignition switch to OFF position.
2) Check for fuse blown at “M ETER” fuse in junction block
assembly.
Is “METER” fuse in good condition? Go to Step 5.
Replace “METER” fuse
and check for short.
5 Combination meter power supply check
1) Remove combination meter referring to “Combination
Meter Removal and Installation in Section 9C”.
2) Check for proper connection to combination meter connector at “G28-31” and “G28-16” terminals.
3) If OK, then turn ignition switch to ON position and measure voltage between combination meter connector
at “G28-31” terminal and vehicle body ground.
Is it 10 – 14 V? Go to Step 6.
“RED/BLK” wire is open
circuit.
6 Combination meter circuit check
1) Turn ignition switch to OFF position.
2) Measure resistance between “G28-16” terminal of
combination meter connector and vehicle body ground.
Is resistance 1
Ω or less? Substitute a known-
good combination meter
and recheck. If MIL still
remains OFF, substitute
a known-good ECM and
recheck.
“BLK/ORN” wire is open
or high resistance
circuit.

DTC Troubleshooting
NOTE
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors re ferring to “Inspection of ECM and Its Circuits”.
• Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.

ABS Warning Light Does Not Come ON at Ignition Switch ONS7RS0B4504008
Wiring Diagram
Circuit Description
Operation (ON/OFF) of ABS warning light is controlled by ABS contro l module through lamp driver module in
combination meter.
If the antilock brake system is in good condition, ABS control module turns ABS warning light ON at the ignition switch
ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ABS warning light is
turned ON continuously by ABS control module. Also, it is turned ON continuously by la mp driver module when the
connector of ABS control module is disconnected.

ESP ® Warning Lamp Does Not Come ON at Ignition Switch ONS7RS0B4604008
Wiring Diagram
Circuit Description
Operation (ON/OFF) of ESP ® warning lamp is controlled by ESP ® control module through lamp driver module in
combination meter.
If ESP ® system is in good condition, ESP ® control module turns ESP ® warning lamp ON at the ignition switch ON,
keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ESP ® warning lamp is
turned ON continuously by ESP ® control module. Also, it is turned ON continuously by lamp driver module when the
connector of ESP ® control module is disconnected.Inspection Item Referring section

Troubleshooting
ESP® Warning Lamp Comes ON SteadyS7RS0B4604009
Wiring Diagram
Refer to “Wiring Diagram” under “ESP ® Warning Lamp Does Not Come ON at Ignition Switch ON”.
Circuit Description
Refer to “Circuit Description” under “ESP ® Warning Lamp Does Not Come ON at Ignition Switch ON”.
Troubleshooting Step Action Yes No
1 Check warning lamp
1) Turn ignition switch to ON position.
Do other warning lamps come ON? Substitute a known-
good combination meter
and recheck. If ESP®
warning lamp remains
OFF, substitute a
known-good ESP ®
hydraulic unit / control
module assembly and
recheck. Go to Step 2.
2 Check fuse
Is Circuit fuse fo r combination meter in good condition? Go to Step 3. Replace fuse and check
for short circuit to
ground.
3 Check combination meter power supply circuit
1) Remove combination meter wit h ignition switch turned
OFF.
2) Check for proper connection to combination meter connector terminal at “G28-31” and “G28-16”.
3) If OK, turn ON ignition switch and measure voltage between connector terminal “G28-31” and vehicle body
ground.
Is it 10 – 14 V? Go to Step 4. Repair power supply
circuit for combination
meter.
4 Check combination me ter ground circuit
1) Measure resistance between connector terminal “G28- 16” and vehicle body ground.
Is resistance less than 2
Ω? Replace combination
meter.
“BLK/ORN” circuit open
or high resistance.
Step
Action YesNo
1 DTC Check for ESP ®
1) Perform diagnostic trouble code check.
Is there any DTC(s)? Go to applicable DTC
diag. flow.
Go to Step 2.
2 Check fuse
Are main fuses for good condition? Go to Step 3.
Replace fuse and check
circuit for short to
ground.
3 Check ESP ® control module power supply circuit
1) Turn ignition switch to OFF.
2) Disconnect ESP ® control module connector.
3) Check for proper connection to ESP ® control module
connector at terminals “E85-35”, “E85-16” and “E85-47”.
4) If OK, then turn ignition switch to ON position and measure voltage between terminal “E85-35” and vehicle
body ground.
Is it 10 – 14 V? Go to Step 4.
“GRN/ORN” circuit
open.
