Reset Procedure

The A/C Cooldown Test:
- is actuated with the DRB III.
- checks A/C system performance based on evaporator temperature sensor input.
- will not run if ambient temperature is below 12.7 °C (55 °F)
- will pass if the evaporator temperature drops 6.7 °C (20 °F) within two minutes of starting the test.
- faults display on the DRB III as test messages only after running the test.
- faults will not display on the DRB III as Diagnostic Trouble Codes.
- will cause the A/C mode switch status indicator to flash while the test is running.
- If the test fails, the status indicator will continue to flash until the test returns passed. It will also prevent the EBL mode switch status indicator from indicating EBL operating status. However, the EBL mode switch will continue to function in this state.
