8) A/C ON
The ECM will turn the cooling fans on at low speed when the A/C system is on. The ECM
will change to high speed when the high side A/C pressure reaches 1860 kPa (269.8 psi).
The cooling fans will return to low speed when the high side A/C pressure reaches 1378 kPa
(199.8 psi). ·

9) ENGINE COOLANT TEMPERATURE SENSOR
The Engine Coolant Temperature (ECT) sensor uses a temperature to control the signal
voltage to the Engine Control Module (ECM).
10) COOLANT TEMPERATURE GAUGE
The coolant temperature gauge controls the instrument panel temperature indicator. The
coolant temperature gauge is located with ECT sensor.

AIR CONDITIONING SYSTEM
3. FFF GENERAL INFORMATION
The system is to increase the coolant temperature quickly by firing diesel fuel in the burner that
is installed in engine cooling system when in winter time the ambient temperature and engine
coolant temperature is low. (Option)
FFH System consists of independent fuel lines, fuel pump, coolant circuit, coolant ciculation
pump, electrical glow plug and exhaust system by driver’s intention because FFH system
is automatically.
Operated according to the coolant temperature and the ambient temperature.
FFH system operates up to more than 2 minutes to burn the residual fuel inside the system
when driver stop the engine during its operation. Therefore, a certain period of FFH operation
after stopping the engine is not a malfunction.
