(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.

Tail lamp AUTO switching off
The tail lamp relay is turned ON or OFF according to the ON/OFF operation of the tail lamp switch. A. Operation 1.
When the ignition is turned OFF or the ignition key is turned to the ACC ON position (ignition key
removed) with the tail lamp switch ON.
After this, the tail lamp relay is turned OFF automatically when the driver door is opened and then
closed. (with tail lamp switch ON) B.
C. Operation 2.
When the ignition is turned ON (ignition key inserted) after the operation 2, the tail lamp relay is turned
ON. D. Operation 3.
The ignition is turned OFF or the ACC is turned ON (ignition key removed).
After the tail lamp is turned ON, the lamp relay is not turned OFF automatically when the driver door is
opened and then closed. (with tail lamp switch ON) E.
F. Operation 4.
To reset, turn the ignition ON (ignition key inserted)

position.
The door LOCK relay is activated for 0.5 seconds (T1). A.
B. Operation 1.
The driver and passenger door LOCK knob switches are in the UNLOCK position from LOCK
position.
The door UNLOCK relay is activated for 0.5 seconds (T2). C.
D. Operation 2.
All open doors are closed.
The LOCK signal is input within 0.5 seconds (T3).
The UNLOCK signal for all doors is output once for 0.5 seconds (T4). E.
F.
G. Operation 3.
14. CENTRAL DOOR LOCKING SYSTEM CONTROL
For BCM with SKM, sleep mode is deactivated by receiving the status signals from the driver door
knob switch, passenger door knob switch, rear LH/RH door knob switch, and central door
LOCK/UNLOCK switch through the wiring.
If all doors are unlocked 5 times within 1 minute after door LOCK signal output, because of faulty
door knob switch and door open switch, the doors are forced to lock and not allowed to unlock.
However, the UNLOCK conditions are met, the UNKLOCK signal is input normally. -
-
The door lock/unlock system does not work regardless of the door LOCK/UNLOCK switch position,
when reconnecting the battery. (to reset, turn the ignition ON) -
The signal change from UNLOCK to LOCK is ignored during LOCK/UNLOCK output by the central
door LOCK switch, REKES key, and door handle switch.
If LOCK signal from the switch is input within 0.5 seconds after any door is closed, UNLOCK signal
is output. -

AUTO door LOCK control
REKES LOCK
The vehicle is driven at 30 km/h or more.
The door LOCK relay is activated for 0.5 seconds (T2).
The door LOCK relay is not activated when all doors (except tailgate) are locked or door malfunction
signal is input. A.
B.
C. Operation 1.
The UNLOCK signal by other switch is received.
The door LOCK signal is output 5 times for the switch. F.
G. Operation 3. (during operation 2)
A door is unlocked.
The door LOCK signal is output 5 times (T3) except the door LOCK carried out in operation 1. D.
E. Operation 2. (after operation 1)
The door LOCK system outputs UNLOCK signal automatically when the LOCK output conditions
are met by this function or the ignition is turned ON to OFF. (even when there is no LOCK output
while the vehicle is driven at over 30 km/h under LOCK condition). - If a door is unlocked after the 5 times of LOCK output, the door is regarded as malfunctioning.
If there is a malfunctioning door, the AUTO door LOCK is not activated but the LOCK operation by
the central door LOCK switch is available.
If a malfunction occurs when the vehicle is driven at 30 km/h or more, the AUTO door LOCK will not
be activated even when the vehicle speed decreases to 30 km/h or less and then increases to 30
km/h or more.
The faulty door will be reset when the unlocked malfunctioning door is locked. -
-
-
-
The faulty door will be reset when the ignition is turned OFF.
When one of the door LOCK switches is in LOCK position with the ignition turned OFF, all doors
are unlocked. -

Standby mode operation
When a smart key is identified within 1 m from the vehicle in theft deterrent mode, the SKM sends the
puddle lamp operation signal (10 minutes timer activated) through the B-CAN. If a smart key is
continuously found within 10 minutes the SKM sends the puddle lamp signal again for continuous
operation (up to 2 times within 10 minutes)
