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.

DTC P0010: “A” Camshaft Position Actuator CircuitS7RS0B1104013
System and Wiring DiagramStep Action Yes No
1 DTC check
1) Start engine and recheck DTC of ECM and TCM (for A/T
model) while engine running.
Is there any DTC(s)? Go to Step 2 of “Engine
and Emission Control
System Check”, Step 2
of “A/T System Check in
Section 5A”.Go to Step 2.
2 CAN communication line circuit check
1) Check CAN communication line circuit between
combination meter and ECM, TCM (for A/T model)
referring to Step 3 of “DTC P1674: CAN Communication
(Bus Off Error)”.
Is circuit in good condition? Substitute a known-
good combination meter
and recheck. If MIL still
remains OFF, substitute
a known-good ECM and
recheck.
Repair or replace CAN
communication circuit.
