Charging Refrigerant
1. Connect the manifold gauge to the charging valve and
evacuate the system.
2. Connect the center hose of the gauge to the refrigerant
tank.
3. Open the high pressure valve and charge the system with
350g of refrigerant.
4. Close the high pressure valve and start the engine and run
the compressor.
Notice
Never open the high pressure valve when the compressor
is running. Refrigerant gas will be charged reverse.
5. Slowly open the low pressure valve and charge the system
with refrigerant.
Standard650 - 750 g
6. Close the low pressure valve after charging.
Notice
Checking the pressure through the sight glass is impossible
by applying & R-134a.
7. Stop the engine and disconnect the manifold gauge from
the system.
Operation Check
1. Place a dry bulb thermometer to the front duct.
2. Place a psychrometer close to the inlet of the cooling unit
(under the glove box).
3. Run the engine at 1,500 rpm.
4. Set the blower switch at ‘HI’ and A/C switch ‘ON”.
5. Set the temperature control lever at ‘COOL’.
6. Set the air flow control at ‘REC’.
7. Check that air conditioning system is stabilized.

Energy Reserve System
Energy reserve system is consisted of condensor and energy switch and will check following items continuously
during system operation.
- High voltage
- Low voltage
- Low rating capacity
- Function of the energy reserve switch
If there is fault in the energy reserve system, warning lamp will turn on. And defects are found by continuous
checking of the condenser voltage, the system will enter overall shutdown status for safety reason.
Shutdown Switch
There is 1 energy shutdown switch in the system and it will be checked during start-up. And it also checks that
condenser is discharging properly. If shutdown switch is short, it will be detected during condensor voltage test.
If squib line fault is obvious, the warning lamp will turn on and the module will enter overall shutdown status.
Accelerometer Check
Accelerometer function will be checked during start-up. During operation, accelerometer off-set signal will be checked,
If there is fault, module will enter overall shutdown status.
ASIC Overheat
Module monitors upper side ASIC overheats continuously. If overheated, the module will enter overall shutdown
status.
Microprocessor Fault
Module checks EEPROM, ROM checksum and RAM during start-up. EEPROM tests checksum operation.
If RAM or ROM checksum is defective, module will not allow start-up continuously but will be re-set,
If EEPROM is defective, warning lamp will turn on and the module will enter overall shutdown status.
During operation, RAM will continuously verify the proper operation of temporary memory program data usage. If
there is fault, the module will enter overall shutdown status and the warning lamp will turn on.
Watchdog Test
Watchdog function will be tested in start-up. If there is fault during the test, warning lamp will turn on and the module
will enter overall shutdown status.

Caution: 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.
