Test Description
The following test measures the A/C system under the following conditions:
- The current ambient air temperature
- The current ambient air humidity
- The high side pressure of the A/C system
- The low side pressure of the A/C system
- The temperature of the air being discharged into the passenger compartment
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 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 temperatures.
