a. Overview
The supplementary electrical heater is installed in DI engine equipped vehicle as a basic equipment. The
PTC system is operated according to two temperature values measured at the coolant temperature
sensor and HFM sensor. This device is mounted in the heater air outlet and increase the temperature of
air to the passenger compartment. Because PTC system is heated by electrical power, high capacity
alternator is required. PTC does not operate during engine cranking, while the battery voltage is lower
than 11 V or during preheating process of glow plugs.

1) Drive Belt
Overview
There are two types of belt system; EPS (Electric Power Steering) and HPS (Hydraulic Power Steering).
In the vehicle with ESP, instead of power steering pulley, the idle pulley is installed on the engine.
The belt system is a single belt drive system which uses single V-belt with 6 grooves. This design
provides the long life span and minimizes the belt slip and noise.

Output Test
Disconnect the cable connected to the B
terminal on the alternator. Connect one
end of the ammeter to the B terminal and
the other end to the cable connected to
the B terminal.
Measure the maximum output value.
(Maintain the engine speed between
2,500 and 3,000 rpm.)
(Turn the headlamp and all the electrical
switches on.) 1.
2.Pass: If the measured current
is 45 A or higher.
Fail: If the measured current is
less than 45 A.
Check the current of the B
terminal. -

Move the gear selector lever to the neutral
position.
Maintain the engine speed at 2,500 rpm
with the vehicle unloaded.
(Turn all the electrical switches off.) 1.
2.Open circuit: If the measured
current is 5 A or higher. -
Disconnect the negative cable from the
battery.
Remove the B terminal and turn off the
ignition switch.
Measure the resistance between the L
and F terminals with an ohmmeter. 1.

Using battery tester
PASS (11.0 V or more): Explain to the customer that the battery is reusable.
Need to be charged (9.0 to 11.0 V): Charge the battery with a charger and reinstall it. Explain it to the
customer.
Need to be replaced (9.0 V or more): The battery should be replaced due to overdischarging. -

How to use battery tester
Determine battery capacity by fixing current
(load capacity) and time and varying voltage.
Determine battery capacity based on the
amount of voltage drop when discharging a
fixed load capacity (120 A) for 5 seconds.
Connect the tester to the battery and read the
display while applying a load for 5 seconds. -

Battery
It converts the chemical energy to the
electrical energy and supplies power to the
corresponding electric units when starting the
engine.
1. OVERVIEW
The charge system is designed to supply electrical energy to the vehicle while driving, and supplies a
constant direct current voltage by converting mechanical rotational movement to electrical energy. The
voltage regulator on the back of the alternator controls the generated voltage in all rotating ranges and
adjusts the system voltage according to the electric load and ambient temperature change.

B+ wiringAlternator
The alternator charges the battery and
supplies power to each electric unit by
converting the mechanical energy to the
electrical energy.
