Front Door Limit Switch Reset (Driver side
only)
RESET CONDITIONS
After each of the following operations are performed, reset the
limit switch (with built-in motor).
+Regulator removal and installation
+ Removal of motor from regulator
+ Operation of regulator as a single unit
+ Door glass removal and installation
+ Glass run removal and installation
RESET PROCEDURES
After installing parts, proceed as follows:
1. Close the door window completely.
2. Press the reset switch and open the door window completely.
3. Release the reset switch. After making sure the reset switch
has returned to the original position, close the door window
completely.
4. The limit switch is now reset.
CAUTION:
Be sure to manually open or close the door window. (Do not
use the automatic open-close procedures.)

Fuel Injection Control System
DESCRIPTION
System description
Three types of fuel injection control are provided to accommodate engine operating conditions; normal
control, idle control and start control. The ECM determines the appropriate fuel injection control. Under each
control, the amount of fuel injected is compensated to improve engine performance.
Pulse signals are exchanged between ECM and electronic control fuel injection pump (control unit is built-
in). The fuel injection pump control unit performs duty control on the spill valve (built into the fuel injection
pump) according to the input signals to compensate the amount of fuel injected to the preset value.

Sensor Input Signal to ECM ECM Function Actuator
Engine coolant temperature sensor Engine coolant temperature
Fuel injection con-
trol (start control)Electronic control fuel injec-
tion pump Crankshaft position sensor (TDC) Engine speed
Ignition switch Start signal
When the ECM receives a start signal from the ignition switch,
the ECM adapts the fuel injection system for the start control.
The amount of fuel injected at engine starting is a preset program
value in the ECM. The program is determined by the engine
speed and engine coolant temperature.
For better startability under cool engine conditions, the lower the
coolant temperature becomes, the greater the amount of fuel
injected. The ECM ends the start control when the engine speed
reaches the specific value, and shifts the control to the normal
or idle control.

Air conditioner switch Air conditioner signal
Heat up switch Heat up switch signal
When the ECM determines that the engine speed is at idle, the fuel injection system is adapted for the idle
control. The ECM regulates the amount of fuel injected corresponding to changes in load applied to the
engine to keep engine speed constant. The ECM also provides the system with a fast idle control in response
to the engine coolant temperature and heat up switch signal.

REAL TIME DIAGNOSIS IN DATA MONITOR MODE
CONSULT-II has two kinds of triggers and they can be selected
by touching ªSETTINGº in ªDATA MONITORº mode.
1) ªAUTO TRIGº (Automatic trigger):
+The malfunction will be identified on the CONSULT-II screen
in real time.
In other words, DTC will be displayed if the malfunction is
detected by ECM.
At the moment a malfunction is detected by ECM, ªMONI-
TORº in ªDATA MONITORº screen is changed to ªRecording
Data ... xx%º as shown at left, and the data after the mal-
function detection is recorded. Then when the percentage
reached 100%, ªREAL-TIME DIAGº screen is displayed. If
ªSTOPº is touched on the screen during ª Recording Data ...
xx%º, ªREAL-TIME DIAGº screen is also displayed.
The recording time after the malfunction detection and the
recording speed can be changed by ªTRIGGER POINTº and
ªRecording Speedº. Refer to CONSULT-II OPERATION
MANUAL.
2) ªMANU TRIGº (Manual trigger):
+DTC will not be displayed automatically on CONSULT-II
screen even though a malfunction is detected by ECM.
DATA MONITOR can be performed continuously even
though a malfunction is detected.
Use these triggers as follows:
1) ªAUTO TRIGº
+While trying to detect the DTC by performing the ªDTC Con-
firmation Procedureº, be sure to select to ªDATA MONITOR
(AUTO TRIG)º mode. You can confirm the malfunction at the
moment it is detected.
+While narrowing down the possible causes, CONSULT-II
should be set in ªDATA MONITOR (AUTO TRIG)º mode,
especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or
twisting) the suspicious connectors, components and har-
ness in the ªDTC Confirmation Procedureº, the moment a
malfunction is found the DTC will be displayed. (Refer to GI
section, ªIncident Simulation Testsº in ªHOW TO PERFORM
EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCI-
DENTº.)
2) ªMANU TRIGº
+If the malfunction is displayed as soon as ªDATA MONITORº
is selected, reset CONSULT-II to ªMANU TRIGº. By select-
ing ªMANU TRIGº you can monitor and store the data. The
data can be utilized for further diagnosis, such as a compari-
son with the value for the normal operating condition.
