(2) Pre-heating time control based on battery voltage
GCU monitors the battery voltage. If it is low, GCU extends the pre-heating time.
GCU monitors the energy to glow plugs (the amount of pre-heating energy is always same). -
-
GCU monitors the battery voltage. If it is low, GCU extends the pre-heating time to get enough
energy. -
GCU monitors the battery voltage. If it is low, GCU increases PWM duty.. -

(3) Power control
GCU PWM control
This describes the voltage supplying types to glow plugs. -
GCU estimates the temperature of glow plug for pre-heating. To avoid the power loss and
overheat, GCU supplies the lowest power for getting target temperature when turning ON the
ignition from OFF. -
(4) Operation
Frequency: 20~33Hz
PWM control duty ratio
- 1st step: 100%
- 2~3 step: 35%
- 4th step: 23%

1. SYSTEM DESCRIPTION
The starter (start motor) starts the engine with rotational power by converting the electric energy to
the mechanical energy.
When the engine is cranking, the pinion gear meshes with the ring gear. If the ring gear overruns,
the pinion gear clutch overruns to protect the pinion gear.

1. SYSTEM DESCRIPTION
1) Overview
The cruise control is an automatic speed control system that maintains a desired driving speed
without using the accelerator pedal.
The vehicle speed must be greater than 38 km/h to engage the cruise control. This feature is
especially useful for motorway driving.
The cruise control system is a supplementary system, which helps the driver to drive the
vehicle at a desired speed without using the accelerator pedal under the traffic condition
where the vehicle-to-vehicle distance meets the legal requirement..

2) Traffic Conditions for Using Cruise Control
Use the cruise control system only when the traffic is not jammed, driving on motorways or
highways where there is no sudden change in the driving condition due to traffic lights,
pedestrian, etc.
Improper use of the cruise control could be dangerous.
Do not use on winding roadsyy .
Do not use in heavy traffic.
Do not use on slippery, wet roads. -

-
This could result in a loss of control, collision, and/or personal injuries.

2. CONFIGURATION
1) Circuit Diagram
The engine ECU detects the operating conditions of cruise control system, and monitors the
braking performance, vehicle speed, road conditions and ESP system operation. If the engine
ECU determines that there are not any problem to drive in cruise control mode, the vehicle can be
operated by cruise switch signals (decelerating, accelerating, cruising).
