Important: 

1

1. Park the vehicle inside or in the shade.
2. Open the windows in order to ventilate the interior of the vehicle.
3. If the A/C system was operating, allow the A/C system to equalize for about 2 minutes.
4. Turn OFF the ignition.
5. Install the J 43600 .
6. Record the ambient air temperature displayed on the J 43600 .
7. Record the low and high side STATIC pressure readings.

Are both the low side and high side pressures within the specified value?

More than 16°C (60°F) - 345 kPa (50 psi)

More than 24°C (75°F) - 483 kPa (70 psi)

More than 33°C (90°F) - 690 kPa (100 psi)

Important: Record the relative humidity and the ambient air temperature at the time of the test.

1. Close the vehicle doors and windows.
2. Open the drivers door window 12.7-15.2 cm (5-6 in).
3. Select the following HVAC control settings:

•	The Vent mode

•	The Recirculation mode

•	The A/C set to ON

•	The coldest temperature setting

•	The maximum blower speed

•	All A/C outlets set to OPEN

4. Install the temperature probes of the J 43600 in the left and right center panel air outlets.
5. Apply the parking brake.
6. Place the transaxle/transmission in one of the following positions:

•	PARK (Automatic)

•	NEUTRAL (Manual)

7. Start the engine.
8. Operate the A/C system for 5 minutes.
9. Inspect the A/C components for the following conditions:

•	Abnormal frost areas

•	Unusual noises

Important: Press the RESET button, before using the print function of the J 43600 .

10. Print the following information:

•	The panel outlet air temperatures

•	The low-side pressure

•	The high-side pressure

11. Compare the low and high side pressures and the panel output temperatures to the A/C performance table below.

Does all the data recorded fall within the specified ranges of the A/C performance table?

--

Go to Step 4

Go to Step 3

3

If the pressures and temperatures recorded do not fall within the specified ranges:

1. Continue to operate the A/C system for an additional 5 minutes.
2. Reset the J 43600 and record the pressures and temperatures again.
3. Compare the low and high side pressures and the panel output temperature to the A/C performance table.

Does all the data recorded fall within the specified ranges of the A/C performance table?

--

Go to Step 8

Go to Step 4

Do the high and low side pressures fall within the specified ranges, but the panel outlet temperatures do not?

--

Go to Air Conditioning (A/C) Diagnostics - Pressure Zone A

Go to Step 5

Is the low side pressure greater than the specified range, but the high side pressure within or less than the specified range?

--

Go to Air Conditioning (A/C) Diagnostics - Pressure Zone B

Go to Step 6

Are the low and high side pressures both greater than the specified ranges?

--

Go to Air Conditioning (A/C) Diagnostics - Pressure Zone C

Go to Step 7

Is the high side pressure greater than the specified range, but the low side pressure is within or less than the specified range?

--

Go to Air Conditioning (A/C) Diagnostics - Pressure Zone D

Go to Step 8

Operate the system in order to verify the test results.

Did you find the same results?
