WELCOME LIGHT FUNCTION
WELCOME LIGHT FUNCTION : System DiagramINFOID:0000000009461786
WELCOME LIGHT FUNCTION : System DescriptionINFOID:0000000009461787
The welcome light function operates as per the following. When the Intelligent Key is within the outside key
antenna detection area, the BCM turns on interior room lamp
* and operates heart beat operation of the push-
button ignition switch.
*: Settings for map lamp, foot lamp, personal lamp, and puddle lamp are available.
OPERATION DESCRIPTION
• When the BCM detects that the Intelligent Key is within the outside key antenna detection area. BCM trans-
mits the request signal to the Intelli gent Key and check it is near the door.
• Intelligent Key receives the request signal and transmits the key ID signal to the BCM via remote keyless entry receiver.
• BCM receives the key ID signal and compares it with the registered key ID.
• BCM illuminates lamps that are set, when key ID verification is OK.
TIMER FUNCTION
BCM can operate welcome light function using the timer function for 9 days after key switch is turned OFF.
The timer function resets when the engine is started
*.Operating period of timer function may differ depending
on battery size.

to the fuel cut When there is an open circuit on MIL circuit, the ECM cannot warn the
driver by lighting up MIL when there is malfunction on engine control
system.
Therefore, when electrical controlled throttle and part of ECM related
diagnoses are continuously detected as NG for 5 trips, ECM warns the
driver that engine control system malfunctions and MIL circuit is open
by means of operating fail safe function.
The fail safe function also operates when above diagnoses except MIL
circuit are detected and demands the driver to repair the malfunction. EC-517, "Compo-

SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
time the valve remains open (injection pulse duration). T he amount of fuel injected is a program value in the
ECM memory. The program value is preset by engi ne operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from t he crankshaft position sensor (POS), camshaft position
sensor (PHASE) and the ma ss air flow sensor.
VARIOUS FUEL INJECTION I NCREASE/DECREASE COMPENSATION
In addition, the amount of fuel injected is compens ated to improve engine performance under various operat-
ing conditions as listed below.

• During warm-up
• When starting the engine
• During acceleration
• Hot-engine operation
• When selector lever is changed from N to D
• High-load, high-speed operation
• During deceleration
• During high engine speed operation

SYSTEM
FUEL INJECTION TIMING
Two types of systems are used.
• Sequential Multiport Fuel Injection System
Fuel is injected into each cylinder during each engine cycle according to the firing order. This system is used
when the engine is running.
• Simultaneous Multiport Fuel Injection System
Fuel is injected simultaneously into all four cylinder s twice each engine cycle. In other words, pulse signals
of the same width are simultaneously transmitted from the ECM.
The four injectors will then receive the signals two times for each engine cycle.
This system is used when the engine is being started and/ or if the fail-safe system (CPU) is operating.
FUEL SHUT-OFF
Fuel to each cylinder is cut off during deceleration, operation of the engine at excessively high speeds or oper-
ation of the vehicle at excessively high speeds.

FUEL FILLER CAP WARNING SYS TEM : System Description
INFOID:0000000009462101
SYSTEM DIAGRAM
SYSTEM DESCRIPTION
The fuel filler cap warning system alerts the driver to the prevention of the fuel filler being left uncapped and
malfunction occurrences after refueling, by turning ON the fuel filler cap warning display on the combination
meter.
ECM judges a refueled state, based on a fuel level signal transmitted from the combination meter.
When a very small leak is detected through the EVAP leak diagnosis performed after judging the refueled
state, ECM transmits a fuel filler cap warning display signal (request for display ON) to the combination meter
via CAN communication.
When receiving the signal, the combination meter turns ON the fuel filler cap warning display.
CAUTION:
Check fuel filler cap installation condition when the fuel filler cap warning display turns ON.
Reset Operation
The fuel filler cap warning lamp tunes OFF, according to any condition listed below:
• Reset operation is performed by operating the meter control switch on the combination meter. Refer to MWI-
18, "Description".
- When the reset operation is performed, the combination meter transmits a fuel filler cap warning reset signal
to ECM via CAN communication. ECM transmits a fuel filler cap warning display signal (request for display
OFF) to the combination meter via CAN communicati on. When receiving the signal, the combination meter
turns OFF the fuel filler cap warning display.
• EVAP leak diagnosis result is normal.
• Fuel refilled.
• DTC erased by using CONSULT.
NOTE:
MIL turns ON if a malfunction is detected in leak diagnosis results again at the trip after the fuel filler cap warn-
ing display turns ON/OFF.

DIAGNOSIS SYSTEM (ECM)
Only one set of freeze frame data (either 1st trip freez
e frame data or freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM me mory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the fol-
lowing priorities to update the data.
For example, the EGR malfunction (Priority: 2) was detected and the freeze frame data was saved in the 2nd
trip. After that when the misfire (Priority: 1) is detected in another trip, the freeze frame data will be updated
from the EGR malfunction to the misfire. The 1st trip freeze frame data is updated each time a different mal-
function is detected. There is no priority for 1st trip freeze frame data. However, once freeze frame data is
stored in the ECM memory, 1st trip freeze data is no longer stored (because only one freeze frame data or 1st
trip freeze frame data can be stored in the ECM). If fr eeze frame data is stored in the ECM memory and freeze
frame data with the same priority occurs later, t he first (original) freeze frame data remains unchanged in the
ECM memory.
Both 1st trip freeze frame data and freeze frame dat a (along with the DTCs) are cleared when the ECM mem-
ory is erased.

RELATIONSHIP BETWEEN MIL, 1ST TRIP DTC, DTC, AND DETECTABLE ITEMS
• When a malfunction is detected for the first time, the 1st trip DTC and the 1st trip freeze frame data are
stored in the ECM memory.
• When the same malfunction is detected in two consec utive trips, the DTC and the freeze frame data are
stored in the ECM memory, and the MIL will come on.
• The MIL will turn OFF after the vehicle is driven 3 time s (driving pattern B) with no malfunction. The drive is
counted only when the recorded driving pattern is met (as stored in the ECM). If another malfunction occurs
while counting, the counter will reset.
• The DTC and the freeze frame data will be stored until the vehicle is driven 40 times (driving pattern A) with-
out the same malfunction recurring (except for Misfire and Fuel Injection System). For Misfire and Fuel Injec-
tion System, the DTC and freez e frame data will be stored until the vehicle is driven 80 times (driving pattern
C) without the same malfunction recurring. The “TIM E” in “SELF-DIAGNOSTIC RESULTS” mode of CON-
SULT will count the number of times the vehicle is driven.
• The 1st trip DTC is not displayed when the self-diagnosis results in OK for the 2nd trip.
