A/C Cooldown Test: Notes

The A/C Cooldown Test:

• is actuated with a scan tool.
• tests A/C system performance based on evaporator temperature sensor input.
• will fail if evaporator starting temperature is below 18° C (65° F) when initiating the test.
• will pass if the evaporator temperature drops 11° C (20° F).
• indicates test outcome by displaying one or more test status messages on the scan tool. These messages will clear after paging back out of this test function. Therefore, is it important to note all of the messages before doing so.
• will cause the A/C status indicator to flash while the test is running.
