bubble in window.
2. Use filling instrument package to check the refrigerant pressure.
This is a type to use filling pressure meter to check the malfunction position. In following situations, read
the meter.
Testing condition:
zSwitch is set up at inner air cycle, and the inlet temperature is 30-50°C.
zEngine runs at the speed of 1500 rpm.
zSet up the speed control switch of fan at “HI” position.
zTemperature control switch is set up at “COOL” position.
zA/C switch turns to “ON”.

 234 
When upgrading compressor assembly, it is necessary to reclaim the refrigerant in system at first.
Refrigerant oil quantity added by new compressor should be calculated by following formula.
Refrigerant oil standard quantity of new compressor:
(Inner Refrigerant oil quantity of new compressor:60 ± 10ml)-(Inner discharged Refrigerant oil quantity
of old compressor)=(Refrigerant oil quantity consumed by the system when changing)
Note:
zWhen checking the Refrigerant oil quantity, please refer to the notes on page 206.
zFor there is some Refrigerant oil in automobile pipeline, if some Refrigerant oil is not discharged
when assembling new compressor, this will incur the Refrigerant oil in system is too much to make
the system heat exchange become bad and air conditioning become invalid.

Normal: malfunction diagnosis ends
Abnormal: change related wiring harness.
8. Malfunction of impact output
Malfunction of safety airbag assembly at the side of passenger (resistance is too big
or too small, short circuit, grounding and so on)
Resting conditionWarning
zIf the treatment is wrong, safety airbag assembly and pre-tension safety belt might be
triggered to unfold and tighten to make heavy human hurt, so, before the treatment, it
is necessary to read repairing warnings carefully.
Refer to repairing warning of safety airbag system.
Possible reason
zConnector between impact output circuit and electronic control unit of safety airbag sys-
tem has malfunction.
zConnector between safety airbag system unit and grounding position has malfunction.
zThe circuit between impact output circuit and electronic control unit of safety airbag
system happens open circuit or short circuit.
zCircuit between safety airbag system unit and grounding position happens open circuit
or short circuit.
zSafety airbag system unit has malfunction.
(1) Check whether this airbag controller has impact output function
a. Set ignition switch at LOCK position
b. Loosen the cathode cable of battery and keep this state for one minute at least
(2) Check whether the connection of impact output connector is good,
(3) Check whether the impact output connecting wire is earth or is short connecting with other wires,
(4) Check whether impact output connecting wire is open circuit,
(5) Check whether the central control door lock control system or electric injection control system of
engine has been changed,
Note: If repairing it by the steps above and requirements, indicating light or diagnostic tool
could display the mistakes before repairing all the time, please do not change it by
yourself, you should contact with the manufacturer as soon as possible avoid wrong
