DESCRIPTION
The MIL (Malfunction Indicator Lamp) is used to indicate vehicle malfunctions detected by the ECM.
When the ignition switch is turned to the ON position, power is supplied to the MIL circuit, and the ECM provides the circuit ground which illuminates the MIL.
The MIL operation can be checked visually. When the ignition switch is first turned to the ON position, the MIL should be illuminated and should then turn off. If the MIL remains illuminated or is not illuminated, conduct the following troubleshooting procedure using the intelligent tester.

INSPECTION PROCEDURE
1 CHECK THAT MIL IS ILLUMINATED
Result

2 CHECK WHETHER MIL TURNS OFF
Standard: MIL goes off.
3 CHECK HARNESS AND CONNECTOR (CHECK FOR SHORT IN WIRE HARNESS)

OK: MIL is not illuminated.
4 CHECK HARNESS AND CONNECTOR (COMBINATION METER - ECM)

Standard resistance (Check for Open)

Standard resistance (Check for Short)

REPAIR OR REPLACE HARNESS OR CONNECTOR (COMBINATION METER - ECM)
5 CHECK THAT ENGINE STARTS
Result

HINT: *: The intelligent tester cannot communicate with the ECM.
6 CHECK HARNESS AND CONNECTOR (COMBINATION METER - BODY GROUND)

Standard voltage

7 CHECK HARNESS AND CONNECTOR (COMBINATION METER - ECM)

Standard resistance (Check for short)

Standard resistance (Check for Short)

1. DATA LIST
HINT:
Using the intelligent tester to read the Data List allows
the values or states of switches, sensors, actuators and
other items to be read without removing any parts. This
non-intrusive inspection can be very useful because
intermittent conditions or signals may be discovered ...
Slide Door Closer RH does not Operate
DESCRIPTION
The slide door ECU RH controls the slide door closer. In response to the
signals output from the switches
in the slide door lock, the slide door closer drives the closer motor.
HINT:
The slide door closer system operates regardless of the power slide door main
switch ON / OFF.

Jam Protection Function Activates During Power Slide Door LH
Operation
DESCRIPTION
It may be caused by ill-fitting slide door, faulty touch sensor or
faulty pulse sensor.
The power slide door ECU activates the slide motor to open / close
the power slide door, thus
controlling the power slide door operation. For jam and foreign object
detect ...
