Test condition
3.
Maintain test condition until A/C system becomes stable. (Approximately 10 minutes)
4.
Check that test results of “recirculating-to-discharge air temperature” and “ambient air temperature-to-
operating pressure” are within the specified value.
5.
When test results are within the specified value, inspection is complete.
If any of test result is out of the specified value, perform diagnosis by gauge pressure. Refer to
.
