CAUTION: Good ventilation is necessary in the area where electronic A/C leak testing is to be carried out. If the surrounding air is contaminated with refrigerant gas, the leak detector will indicate this gas all the time. Odors from other chemicals such as antifreeze, diesel fuel, disc brake cleaner, or other cleaning solvents can cause the same problem. A fan, even in a well-ventilated area, is very helpful in removing small traces of contamination from the air that might affect the leak detector.

NOTE: The system pressure should be between 413-551 kPa (60-80 psi) at 24°C (75°F) with the engine off.

If a leak is found, discharge and recover the refrigerant. For additional information, refer to AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING .
- Repair the system.
- Test the system for normal operation.
