Pumping Out of A i r Conditioning System to the Vacuum and Addition of Refrigeration Oil
Connect the manifold pressure gauge with the pipe of air conditioner (compressor) and the multi-purpose adapter of the vacuum
pump for the purpose of pumping out of the system to the vacuum state.
Before pumping out to the vacuum, turn on the high-pressure and low-pressure valve of the
manifold pressure gauge and the end valve
(if provided) of the vacuum pump, then press the button ON to start the vacuum pump, the duration shall be more than 20 minutes
.
When the reading of manifold pressure gauge is -760mmHg or below, turn off the high-pressure and low-pressure valve (if opened)
,
and press the switch to turn off the vacuum pum
p.
1 . check the air tightness
Continue to check the pressure reading of the manifold pressure gauge after turning off the vacuum pump.
If the pressure reading remains unchanged within 20 minutes after the vacuum pump stops running, then it indicates that th
e
refrigerating system has no leakage, the operator can proceed with next work; while change of the reading indicates that the
system has the leakage. Launch the examination and pump out to the vacuum after the leakage is fixed.
2 . Injection of the refrigerant
When the air tightness of the system is verified correct, connect the refrigerant reservoir (or gas bottle) with one end of the yellow
a ir-charging hose, while other end of yellow air-charging hose is connected with the liquid injection port in the middle of the
manifold pressure gauge. Ensure that the refrigerant reservoir is connected firmly with the nut of air-charging hose, then turn on
the valve of refrigerant reservoir; at this time, the high-pressure and low-pressure is closed, use a tip screw driver or other
similar
tools and press the by-pass valve spool for 1~ 2 seconds to discharge out the air in the air-charging hose and the manifold
pressure gauge.

4. Attention:
a. when a new compressor is used to substitute for the old one, the oil must be released to some extent that its oil volume is the
same as that of old compressor so as to avoid the influence over the refrigeration effect due to too much oil.
b. when an old or repaired compressor is employed, the volume of the refrigeration oil in the compressor must be kept the sam
e
as that of the replaced
compressor.

Safety airbag-12
Begin the test with diagnostic communication with special diagnostic device (X-431 diagnostic tester) and ECU
to find out the failure causes, do the next test providing communication is not successful.
Procedure Te s t Operation
Yes Next procedure
1 Test the battery
Test the battery voltage
Is the voltage higher 9V? No Insufficient battery supply.
Test the charging/discharging
system, then go to step 5.
Yes Next step
2 Test the wiring harness connection between ECU and
combined instrument.
Place the ignition switch in LO C K position。
Shut off the battery negative.
O pen the central channel guard plate.
Shut off the instrument combined connector clip
Connect the negative of battery
Place the ignition switch in ON position.
Check whether the instrument connector clip terminal
voltage is 12V(power supply and instrument line) No Check the circuit and continue the
operation according to step 5.
Yes Next step
3 Place the ignition switch in LO C K position。
Check the connection of corresponding terminals between
instrument connector clip and diagnostic interface
(diagnose the two ends of K-line) No Repair or replace the wiring
harness and continue according to
step 5
Yes Next step
3 Make sure the shutoff of accumulator negative line and
keep the status for at least 1 minute.

Failure code
$9032 Low power-supply voltage for SRS safety airbag system electronic-control unit
Test condition Warning
The test condition of this failure is the failure code that may not emerge before the test, DTC conducts the test,
and the preparatory work must be done before the test because the damage to working personnel or system
may be caused by the incorrect op eration during the test.
