(3) Accelerometer Control
a. Resetting the pilot injection
The accelerometer is used to reset the pilot injection flow in closed loop for each injector. This method
allows the correction of any injector deviations over a period of time. The principle of use of the
accelerometer is based on the detection of the combustion noises.
The sensor is positioned in such a way as to receive the maximum signal for all the cylinders. The raw
signals from the accelerometer are processed to obtain a variable which quantifies the intensity of the
combustion. This variable, known as the ratio, consists of the ratio between the intensity of the
background noise and the combustion noise.
A first window is used to establish the background noise level of the accelerometer signal for each
cylinder. This window must therefore be positioned at a moment when there cannot be any
combustion.
The second window is used to measure the intensity of the pilot combustion. Its position is such that
only the combustion noises produced by the pilot injection are measured . It is therefore placed just
before the main injection. 1.
2.
The accelerometer does not allow any evaluation of the quantity injected. However, the pulse value will
be measured when the injector starts injection and this pulse value is called the MDP (Minimum Drive
Pulse). On the basis of this information, it is possible to efficiently correct the pilot flows. The pilot
injection resetting principle therefore consists of determining the MDP, in other words the pulse
corresponding to the start of the increase in value of the ratio (increase of vibration due to fuel
combustion).

This is done periodically under certain operating conditions. When the resetting is finished, the new
minimum pulse value replaces the value obtained during the previous resetting. The first MDP value is
provided by the C3I. Each resetting then allows the closed loop of the MDP to be updated according to
the deviation of the injector.
b. Detection of leaks in the cylinders
The accelerometer is also used to detect any injector which may have stuck open. The detection
principle is based on monitoring the ratio. If there is a leak in the cylinder, the accumulated fuel self-
ignites as soon as the temperature and pressure conditions are favorable (high engine speed, high load
and small leak).
This combustion is set off at about 20 degrees before TDC and before main injection.
The ratio therefore increases considerably in the detection window. It is this increase which allows the
leaks to be detected. The threshold beyond which a fault is signaled is a percentage of the maximum
possible value of the ratio.
Because of the severity of the recovery process (engine shut-down), the etection must be extremely
robust.
An increase in the ratio can be the consequence of various causes:
Pilot injection too much
Main combustion offset
Fuel leak in the cylinder -
-
-
If the ratio becomes too high, the strategy initially restricts the pilot injection flow and retards the main
injection. If the ratio remains high despite these interventions, this shows that a real leak is present, a
fault is signaled and the engine is shut down.
c. Detection of an accelerometer fault
This strategy permits the detection of a fault in the sensor or in the wiring loom connecting the sensor to
the ECU.
It is based on detection of the combustion. When the engine is idling, the detection window is set too low
for the combustion caused by the main injection. If the ratio increases, this shows that the accelerometer
is working properly, but otherwise a fault is signaled to indicate a sensor failure. The recovery modes
associated with this fault consist of inhibition of the pilot injection and discharge through the injectors.

Windshield wiper and washer switch function
The wiper system operates the wiper and washer using the signals from the multi-function switch, and
receives rain sensing signal from the rain sensor unit.
4. WIPER CONTROL
1. MIST
When the wiper switch is pulled up and
released, the wiper cycles once and then
returns to the park position. -
2. OFF
Stops the windshield wiper operation. -
3. AUTO
When the wiper switch is set to the AUTO
position, the wiper speed is adjusted
automatically according to the amount of
rain measured by the rain sensor mounted
on the windshield. -
4. LO/HI
When the wiper switch is set to the LO
position, the wiper speed is decreased.
When the switch is set to the HI position, the
wiper speed is increased. -
5. Wiper speed control switch
The wiper speed can be adjusted with this
switch as follows when the wiper switch is in
AUTO position.
* FAST: increases wiper speed
* SLOW: decreases wiper speed -6. AUTO washer switch

washer fluid is sprayed once and the wiper is
operate 4 times. Then, the fluid is sprayed once
again with 3 wiping operations. -

19. SLEEP MODE
If the state of the LOCK switches of driver/passenger/rear doors and tailgate is not changed for 6
seconds with the all doors including tailgate closed and IGN OFF (ignition key removed), even if the
state is not LOCK, the system enters the sleep mode to power down. 1.
If any condition of the (1) is not met, the system enters the wake up mode immediately. 2.
When the room lamp, key hole lamp, tail lamp, or power window is already activated, or all doors are
closed for continuous 30 seconds after the door UNLOCK under the conditions stated in (1), the
system waits in normal mode. If the lamps or power window is deactivated and no change is
detected for 6 seconds after all doors are closed, the system enters the sleep mode. 3.
When the front room lamp is ON, the system turns of the room lamp in 10 minutes and enters the
sleep mode after 6 seconds. 4.
If the coming home light is ON, the system enters the sleep mode when the coming home light
switching off conditions are met. 5.
The sleep mode is deactivated when a door is opened or key is inserted. 6.

Power window main switch
It is mounted to the door trim and can open or close the 4 windows. It has the switches which can lock or
unlock all the doors and windows. The window main switch has the auto open and close function (only
for driver), anti-trap system and driver window safety function.
Driver window safety function
The anti-trap system enables the driver's window to automatically reverse when something is caught in
the window as it is closing. When the sensor detects an obstacle, the window will be lowered
immediately. The anti-trap safety system is available only for the driver's window equipped with the
automatic rolling up (Auto-up) function. The anti-trap safety system does not operate when the window
is about to touch its window frame.
