Air Conditioning (A/C) System Performance Test (LFX)

Air Conditioning (A/C) System Performance Test (LFX)

Test Description

This test measures the operating efficiency of the A/C system under the following conditions:

* The current ambient air temperature

* The current relative 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 number(s) below refer to the step number(s) 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.
