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.

3. INSPECTION
1) Alternator
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.
2.
3.Pass: If the measured
resistance is between 3 and
6Ω.
Faulty rotor coil or slip ring: If
the measured resistance is
less than 3Ω or greater than
6Ω. -
-
Connect the B terminal wiring.
Measure the voltage with the engine
running. 1.
2.
Specification: 12.5V to 14.5V
Faulty IC regulator or field
coil: If the measured voltage
is 14.5V or higher. -
-
Disconnect the negative cable from the battery.
Connect the negative cable again after connecting the ammeter. -
