2. OPERATING PROCESS
1) System Layout
(1) Engine start
SKM performs the authentication process for the SMART key and sends the engine start request to
EMS if there is a normally coded SMART key when pressing the Engine Start/Stop button with the
SKM sends the start request signal to PCAN network and the cranking request to BCAN network by
button.
SKM turns off the IGN2/ACC relay during cranking to shut down the electric loads.
SKM receives the starting status signal from EMS throug PCAN.
EMS starts to crank the engine after checking the pre-heating condition if it receives the engine
cranking request 1 when pressing the Engine Start/Stop button. EMS starts to crank the engine
immediately if it receives the engine cranking request 2 when pressing the Engine Start/Stop button. 1.

Engine start during driving 7.
When pressing the Engine Start/Stop button with IGN ON, the engine start is requested if the
the brake switch is ON (no need authentication for 30 seconds).
When pressing the Engine Start/Stop button with IGN ON, the engine start is requested

Except input of brake switch signal
In vehicle equipped with A/T, when pressing the Engine Start/Stop button for more than 10
seconds with ACC ON, the engine start is requested regardless of brake signal if the gear shift

a. Overview of cooling fan and A/C compressor
The cooling system maintains the engine temperature at an efficient level during all engine operating
conditions. The water pump draws the coolant from the radiator. The coolant then circulates through
water jackets in the engine block, the intake manifold, and the cylinder head. When the coolant reaches
the operating temperature of the thermostat, the thermostat opens. The coolant then goes back to the
radiator where it cools. The heat from automatic transaxle is also cooled down through the radiator by
circulating the oil through the oil pump.
There are two cooling fans (200W+150W) in D20DTF engine. ECU controls the electric cooling fans
with three cooling fan relays to improve the engine torque and air conditioning performance.
For details about A/C compressor and refrigerant pressure sensor, refer to Chapter "Air Conditioning
System" in "Body" section.

Conditions for cooling fan
The cooling fan module controls the cooling fan relay, high speed relay and low speed relay. The cooling
fan is controlled by the series and parallel circuits.

(9) PTC heater control
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.
b. Components
A: PTC 1 (changeable)
B: PTC 2,3 (not changeable)

c. Operation process
The ceramic PTC has a feature that the resistance goes up very high at a certain temperature. There
are three circuits in PTC heater. Only one circuit is connected when PTC1 relay is ON, and two circuits
are connected when PTC2 relay is ON.
