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.

The amount of fuel injected under normal driving conditions is
determined according to sensor signals. The crankshaft position
sensor (TDC) detects engine speed and the accelerator position
sensor detects accelerator position. These sensors send signals to
the ECM.
The fuel injection data, predetermined by correlation between vari-
ous engine speeds and accelerator positions, are stored in the
ECM memory, forming a map. The ECM determines the optimal
amount of fuel to be injected using the sensor signals in compari-
son with the map.

SYSTEM DESCRIPTION
This system improves acceleration when the air conditioner is used.
When the accelerator pedal is fully depressed, the air conditioner is turned off for a few seconds. When engine
coolant temperature becomes excessively high, the air conditioner is turned off. This continues until the cool-
ant temperature returns to normal.

If the engine speed is above 5,500 rpm fuel will be cut off to keep
engine within its working range.

How to Erase DTC (Without CONSULT-II)
1. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Change the diagnostic test mode from Mode II to Mode I by using the data link connector. (See EC-323.)
The emission related diagnostic information in the ECM can be erased by changing the diagnostic test mode.
IIf the battery is disconnected, the emission-related diagnostic information will be lost after approx.
24 hours.
IErasing the emission-related diagnostic information using CONSULT-II is easier and quicker than
switching the diagnostic test mode using the data link connector.
Malfunction Indicator (MI)
1. The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is a bulb check.
IIf the malfunction indicator does not light up, refer to EL sec-
tion (ªWARNING LAMPS/WIRING DIAGRAMº) or see MI &
DATA LINK CONNECTORS.
2. When the engine is started, the malfunction indicator should go
off.
If the lamp remains on, the on board diagnostic system has
detected an engine system malfunction.
If MI illuminates or flashes irregularly after starting engine,
water may have accumulated in fuel filter. Drain water from
fuel filter.
ON BOARD DIAGNOSTIC SYSTEM FUNCTION
The on board diagnostic system has the following three functions.
Diagnostic
Test ModeKEY and ENG.
StatusFunction Explanation of Function
Mode IIgnition switch in

Engine stoppedBULB CHECKThis function checks the MI bulb for damage (blown, open
circuit, etc.).
If the MI does not come on, check MI circuit. (See EC-452.)

MALFUNCTION
WARNINGThis is a usual driving condition. When ECM detects a
malfunction, the MI will light up to inform the driver that a mal-
function has been detected.
