PRECAUTIONS WHEN USING INTELLIGENT TESTER
When using the intelligent tester to troubleshoot the CAN communication line or LIN communication line:
Connect the intelligent tester to the vehicle, and turn a courtesy light switch on and off at 1.5 second intervals until communication between the intelligent tester and vehicle begins.
After all DTCs are cleared, check if the trouble occurs again 6 seconds after the engine switch is turned on (IG).
IF ANY OF FOLLOWING CONDITIONS ARE MET, KEEP ENGINE IDLING WITH AIR CONDITIONING SWITCH ON (ENGINE SPEED AT LESS THAN 2000 RPM) FOR AT LEAST 2 MINUTES
Refrigerant gas has been refilled or parts of the air conditioning system have been replaced.
The engine has not been started for a long time.
If the engine speed is more than 2,000 rpm, the cooler compressor assembly may be damaged.
DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME
ALWAYS WEAR EYE PROTECTION
BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN YOUR EYES OR ON YOUR SKIN
If liquid refrigerant gets in your eyes or on your skin:
Wash the area with lots of cold water.
Do not rub your eyes or skin.
Apply clean petroleum jelly to the skin.
Go immediately to a hospital or see a physician for professional treatment.
NEVER HEAT CONTAINER OR EXPOSE IT TO OPEN FLAME
BE CAREFUL NOT TO DROP CONTAINER OR APPLY PHYSICAL SHOCKS TO IT
DO NOT OPERATE COMPRESSOR WITH INSUFFICIENT REFRIGERANT IN REFRIGERANT SYSTEM
If there is not enough refrigerant in the refrigerant system, oil lubrication will be insufficient and compressor burnout may occur. Necessary care should be taken to avoid this.
DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING
Open and close only the low pressure valve. Opening and closing the high pressure valve could cause the charging cylinder to rupture.
BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT
If the refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy and engine overheating.
DO NOT OPERATE ENGINE AND COOLER COMPRESSOR ASSEMBLY WITHOUT REFRIGERANT
This may damage the inside of the cooler compressor assembly.
