Toyota Corolla (E120): Precaution
1. Do not handle refrigerant in an enclosed area or near an open flame
2. Always wear eye protection
3. 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 cool water.
Caution
: do not rub your eyes or skin.
- apply clean petroleum jelly to the skin.
- go immediately to a physician or hospital for professional treatment.
4. Never heat container or expose it to naked flame
5. Be careful not to drop container and not to apply physical shocks to it
6. Do not operate compressor without enough refrigerant in refrigerant system
If there is not enough refrigerant in the refrigerant system oil lubrication will be insufficient and compressor burnout may occur, so take care to avoid this, necessary care should be taken.
7. Do not open high pressure manifold valve while compressor is operating
If the high pressure valves opened, refrigerant flows in the reverse direction and could cause the charging cylinder to rupture, so open and close the only low pressure valve.
8. Be careful not to overcharge system with refrigerant
If refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy, engine overheating etc.

Symptom confirmation and diagnostic trouble code
Hint:
the diagnostic system in corolla has various functions. The first
function is the diagnostic trouble
code (dtc) check, in which a malfunction in the signal circuits to the ecu
is stored in code form in
the ecu memory. Another function is the input signal check, which checks if
