3) Check for proper connection to each CAN line terminal
of all control module (communicated by CAN)
connectors.
4) If OK, connect connectors of all control module/sensor
communicated by CAN securely.
5) Check communication between scan tool and ECM/TCM
by DTC check in ECM/TCM.
Is it possible to check DTC in ECM and TCM?Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.Go to Step 7.
7CAN line check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of all control module
communicated by CAN.
3) Check all the following CAN lines for open, short to
power circuit, short to ground circuit, short to other CAN
line and high resistance.

10Internal circuit check in ECM
1) Turn ignition switch to OFF position and then disconnect
negative (–) cable at battery.
2) Disconnect TCM connectors.
3) Measure resistance between the followings
• Between CAN High terminal on DLC and “C06-17”
terminal on TCM connector
• Between CAN Low terminal on DLC and “C06-7”
terminal on TCM connector
Is each resistance 0 – 1

Malfunction Indicator Lamp Does Not Come ON with Ignition Switch ON and Engine Stop (but
Engine Can Be Started)
S6RW0D1104011
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.
