C. Key approval process
When turning the ignition switch to ON position, the power is supplied to BCM and ECU. ECU
communicate with the immobilizer key to check if it is valid crypto code. If it is valid, ECU start to control
the engine when turning the ignition switch to START position. The system has 10 seconds of valid
time-out period. If the engine does not start in this period, the key approval process should be done
again.

2. DESCRIPTION AND OPERATION
1) Cleanliness and Care
An automobile engine is a combination of many machined, honed, polished and lapped surfaces with
tolerances that are measured in the ten-thousandths of an inch. When any internal engine parts are
serviced, care and cleanliness are important. A liberal coating of engine oil should be applied to friction
areas during assembly, to protect and lubricate the surfaces on initial operation.
Proper cleaning and protection of machined surfaces and friction areas is part of the repair procedure.
This is considered standard shop practice even if not specifically stated.
Whenever valve train components are removed for service, they should be kept in order.
They should be installed in the same locations, and with the same mating surfaces, as when they were
removed. Battery cables should be disconnected before any major work is performed on the engine.
Failure to disconnect cables may result in damage to wire harness or other electrical parts.
2) On-Engine Service
Disconnect the negative battery cable before removing or installing any electrical unit, or when a
tool or equipment could easily come in contact with exposed electrical terminals.
Disconnecting this cable will help prevent personal injury and damage to the vehicle.
The ignition must also be in LOCK unless otherwise noted.
Notice Any time the air cleaner is removed, the intake opening -
Any time the air cleaner is removed, the intake opening should be covered. This will protect
against accidental entrance of foreign material, which could follow the intake passage into the
cylinder and cause extensive damage when the engine is started. -

1. CHARGING SYSTEM OPERATION
Alternators use a new type of regulator that incorporates a diode trio. A Delta stator, a rectifier bridge,
and a rotor with slip rings and brushes are electrically similar to earlier alternators.
A conventional pulley and fan are used. There is no test hole.
1) Charging Time Required
The time required to charge a battery will vary depending upon the following factors:
Size of Battery ▶
A Completely discharged large heavy-duty battery required more than twice the recharging
time as a completely discharged small passenger car battery. -
Temperature ▶
A longer time will be needed to charge any battery at -18°C (0°F) than at 27°C (80°F).
When a fast charger is connected to a cold battery, the current accepted by the battery will be
very low at first. The battery will accept a higher current rate as the battery warms. -
Charger Capacity ▶
A charger which can supply only 5 amperes will require a much longer charging period than a
charger that can supply 30 amperes or more. -
State-of-Charge ▶
A completely discharged battery requires more than twice as much charge as a one half
charged battery. Because the electrolyte is nearly pure water and a poor conductor in a
completely discharged battery, the current accepted by the battery is very low at first. Later, as
the charging current causes the electrolyte acid content to increase, the charging current will
likewise increase. -
2. STARTING SYSTEM OPERATION
The engine electrical system includes the battery, the ignition, the starter, the alternator, and all the
related wiring. Diagnostic tables will aid in troubleshooting system faults. When a fault is traced to a
particular component, refer to that component section of the service manual. The starting system
circuit consists of the battery, the starter motor, the ignition switch, and all the related electrical wiring.
All of these components are connected electrically.

3. IGNITION SYSTEM OPERATION
This ignition system does not use a conventional distributor and coil. It uses a crankshaft position
sensor input to the Engine Control Module (ECM).
The ECM then determines Electronic Spark Timing (EST) and triggers the electronic ignition system
ignition coil.
This type of distributor less ignition system uses a "waste spark" method of spark distribution. Each
cylinder is paired with the cylinder that is opposite it (2.3L DOHC: 2 - 3 or 1 - 4, 3.2L DOHC: 1 - 6 or 2 -
5 or 3 - 4).
The spark occurs simultaneously in the cylinder coming up on the compression stroke and in the
cylinder coming up on the exhaust stroke.
The cylinder on the exhaust stroke requires very little of the available energy to fire the spark plug.
The remaining energy is available to the spark plug in the cylinder on the compression stroke. These
systems use the EST signal from the ECM to control the EST.
The ECM uses the following information: Engine load (mass air flow sensor, manifold air pressure
sensor).
Engine coolant temperature.
Intake air temperature.
Crankshaft position.
Engine speed (rpm).
1) Electronic Ignition System Ignition Coil
The Electronic Ignition (EI) system ignition coil is located on the cylinder head cover.
The double ended coils receive the signal for the ECM which controls the spark advance. Each
EI system ignition coil provides the high voltage to two spark plugs simultaneously;
3.2L DOHC
T1/1: cylinder 2 and 5
T1/2: cylinder 3 and 4
T1/3: cylinder 1 and 6
The EI system ignition coil is not serviceable and must be replaced as an assembly.

4) Recovery of Set Speed (RESUME)
Even if the cruise control is cancelled, the previous set cruise speed can be recovered by pushing
(Type A) or pulling (Type B) toward the cruise control lever when the current vehicle speed is over 36
km/h without an acceleration intervention. But if you turn off the ignition switch, the memorized set
speed is cleared and you cannot recover the previous set speed.
The resume position should only be used if the driver is fully aware of this speed and wishes to
resume this particular speed.

(2) Using the Cruise Control on Hills
How well the cruise control works on hills depends on the speed, load, and the steepness of the hill.
When going up steep hills, you may have to depress the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to a lower gear to keep your speed down.
Applying the brake takes you out of the cruise control.
And the cruise control system cannot be operated again in driving state. In this case, you should stop
the vehicle, and turn off the ignition switch and then turn it on again. After you do that, you can use the
cruise control s
ystem again. But if the cruise control system isn’t recovered, you should contact
a Ssangyong Dealer for diagnosis of the cruise control system.
Abnormal changes of the gear selector lever can damage the engine. Do not move the gear shift
lever to Neutral while driving at the set speed. Automatic transmission damage may result.
The speed that has been set may not be maintained on uphill or downhill slopes.
The speed may drop to less than the set speed on a steep uphill grade. The accelerator must be
used if you want to maintain that speed.
The speed may increase to more than the set speed on a steep downhill grade. When the speed
increases too much, turn off the cruise control. -

(1) Abnormal Cancellation of the Cruise Control
When the rapid deceleration is applied without braking.
When the rapid acceleration is applied without acceleration pedal intervention.
When the cruise control lever is failed.
When the brake switch and the brake light switch input signal are implausible. 1.

1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITS
80℃
10A 15A
Disconnect the negative cable from the
battery in advance when working on electrical
units. -
Make sure to turn "OFF" the ignition switch
and other lamp switches before
disconnecting or connecting the negative
battery cable. (Otherwise, semiconductor
parts can be damaged.)
Do not drop or appy excessive impact to
sensors and relays. -
If a fuse is blown, replace it with a fuse which
has the correct amperage rating. If you use a
fuse with higher capacity than the
specification, the component can be
damaged or catch fire. -
