The electronic refrigerant leak detector (J-41995) is a delicate device. To use the electronic refrigerant leak detector (J-41995) properly, read the
manufacturer's operating instructions and perform any specified maintenance.
1. Position the probe approximately 5 mm (3/16 in) away from the point to be checked as shown.
2. When checking for leaks, circle each fitting completely with the probe as shown.
3. Move the probe along each component at a speed of approximately 25 - 50 mm (1 - 2 in)/second as shown.
CHECKING PROCEDURE
NOTE: To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette smoke in the vicinity of the
vehicle. Perform the leak test in a calm area (low air/wind movement) so that the leaking refrigerant is not dispersed.
1. Turn the engine OFF.
2. Connect the manifold gauge set (J-39183-C) to the A/C service ports. Refer to "Precautions for Service Equipment".
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.52 kg/sq.cm, 50 psi) above a temperature of 16 degrees C (61 degrees F). If less than
