VQ35DE
Component part Description
Generator (IC regulator) The IC regulator controls the power generation voltage by the tar-
get power generation voltage based on the received PWM com-
mand signal.
When there is no PWM command signal, the generator performs
the normal power generation according to the characteristic of the
IC regulator.
ECM The battery current sensor detects the charging/discharging cur-
rent of the battery. The ECM judges the battery condition based on
this signal.
The ECM judges whether to request more output via the power
generation voltage variable control according to the battery condi-
tion.
When performing the power generation voltage variable control,
the ECM calculates the target power generation voltage according
to the battery condition and sends the calculated value as the pow-
er generation command value to the IPDM E/R.
IPDM E/R The IPDM E/R converts the received power generation command
value into a pulse width modulated (PWM) command signal and
sends it to the IC regulator.
Combination meter (c harge warning lamp) The IC regulator warning function activates to illuminate the
charge warning lamp if any of the following symptoms occur while
generator is operating:
·Excessive voltage is produced.
·No voltage is produced.
Battery current sensor The battery current sensor is located on the negative battery cable
terminal. The battery current sensor detects the charging/dis-
charging current of the battery and sends a voltage signal to the
ECM according to the current value detected.

POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
System DiagramINFOID:0000000009460653
System DescriptionINFOID:0000000009460654
Power generation variable voltage control system has been adopted. By varying the voltage to the generator,
engine load due to power generation of the generator is reduced and fuel consumption is decreased.
NOTE:
When any malfunction is detected in the power generat ion variable voltage control system, power generation
is performed according to the characteristic of the IC regulator in the generator.

PRECAUTIONS FOR BLIND SPOT WARNING (BSW)
• The Blind Spot Warning system is not a replacem
ent for proper driving procedure and are not designed to
prevent contact with vehicles or objects. When c hanging lanes, always use the side and rear mirrors and
turn and look in the direction driver will move to ensure it is safe to change lanes. Never rely solely on the
Blind Spot Warning system.
• The Blind Spot Warning system may not provide a warn ing for vehicles that pass through the detection zone
quickly.
• Do not use the Blind Spot Warning system when towing a trailer.
• Excessive noise (e.g., audio system volume, open v ehicle window) will interfere with the chime sound, and it
may not be heard.
• The rear view camera may not be able to detect and activate Blind Spot Warning when certain objects are present such as:
- Pedestrians, bicycles, animals.
- Several types of vehicles such as motorcycles.
- Oncoming vehicles.
- Vehicles remaining in the detection zone when driver accelerates from a stop.
- A vehicle merging into an adjacent lane at a speed approximately the same as vehicle.
- A vehicle approaching rapidly from behind.
- Another vehicle which overtakes this vehicle rapidly.
• Severe weather or road spray conditions may reduce the abi lity of the rear view camera to detect other vehi-
cles.
• The rear view camera detection zone is designed based on a standard lane width. When driving in a wider
lane, the rear view camera may not detect vehicles in an adjacent lane. When driving in a narrow lane, the
rear view camera may detect vehicles driving two lanes away.
• The rear view camera is designed to ignore most stationary objects, however objects such as guardrails,
walls, foliage and parked vehicles may occasionally be detected. This is a normal operating condition.
PRECAUTIONS FOR BLIND SPOT WARNING
• Do not use the Blind Spot Warning system under the following conditions because the system may not func-
tion properly:
- During bad weather (e.g., rain, fog, snow, wind, etc.)
- When driving on slippery roads, such as on ice or snow, etc.
- When driving on winding or uneven roads.
- When there is a lane closure due to road repairs.
- When driving in a makeshift lane.
- When driving on roads where the lane width is too narrow.
- When driving with a tire that is not within normal tire c onditions (e.g., tire wear, low tire pressure, installation
of spare tire, tire chains, non-standard wheels).
- When the vehicle is equipped with non-original brake parts or suspension parts.
• The rear view camera may not detect lane markers in the following situations and the Blind Spot Warning
system may not operate properly:
- On roads where there are multiple parallel lane marker s; lane markers that are faded or not painted clearly;
yellow painted lane markers; nonstandard lane markers; lane markers covered with water, dirt, snow, etc.
- On roads where discontinued lane markers are still detectable.
- On roads where there are sharp curves.
- On roads where there are sharply c ontrasting objects, such as shadows, snow, water, wheel ruts, seams or
lines remaining after road repairs.
- On roads where the traveling lane merges or separates.
- When the vehicle traveling direction does not align with the lane markers.
- When rain, snow or dirt adheres to the lens of a the rear view camera unit.
- When a sudden change in brightness occurs. (e.g., when the vehicle enters or exits a tunnel or under a
bridge.)
- When steering quickly.
- When the hazard warning flashers are operated.
- When driving on a curve at a high speed.

COMPONENT PARTS
ECM receives the signals as shown in the figure.
Intake Valve Timing Control Solenoid ValveINFOID:0000000009462066
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.
Intake Valve Timing Intermediate Lock Control Solenoid ValveINFOID:0000000009462067
Intake valve timing intermediate lock control solenoid valve is acti-
vated by ON/OFF signals from the ECM.
The intake valve timing intermediate lock control solenoid valve
opens/closes the path of oil pressure acting on the lock key in the
camshaft sprocket (INT).
• When the solenoid valve becomes ON, oil pressure to the lock key
is trained to perform intermediate lock.
• When the solenoid valve becomes OFF, oil pressure is acted on the lock key to release the intermediate lock.
Exhaust Valve Timing Control Position SensorINFOID:0000000009462068
Exhaust valve timing control position sensor detects the protrusion of
the signal plate installed to the exhaust camshaft front end.
This sensor signal is used for sensing a position of the exhaust cam-
shaft.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
