Test Description
The numbers below refer to the step numbers on the diagnostic table.
- 1 This step determines if the A/C system has at least the minimum refrigerant charge required to operate the system without damage.
- 2 This step measures the performance of the A/C system.
- 3 This step is to allow for vehicle variations as well as high ambient air temperatures.
| Step | Action | Values | Yes | No |

Print the following information: The panel outlet air temperatures The low-side pressure The high-side pressure Compare the low and high side pressures and the panel output temperatures to the table below. Does all the data recorded fall within the specified ranges of the table below? | | Go to Step 5 | Go to Step 3 |
| 3 | If the pressures and temperatures recorded do not fall within the specified ranges: Continue to operate the A/C system for an additional 5 minutes. RESET the J 43600 ACR 2000 Refrigerant Station. and record the pressures and temperatures again. Compare the low and high side pressures and the panel output temperature to the table below. Does all the data recorded fall within the specified ranges of the table below? | | Go to Step 5 | Go to Step 4 |
| 4 | Perform the necessary repairs. Refer to A/C Diagnostics Chart . Is the action complete? | | Go to Step 5 | |
| 5 | Operate the system in order to verify the test results. Did you find the same results? | | System OK | Go to Symptoms - HVAC Systems - Manual or Go to Symptoms - HVAC Systems - Automatic |
