·DTCs are not stored when performing the refrigerant shortage check using the GTS.
·*1: This inspection can be judged correctly only if the ambient temperature is within a range of 0 to 49°C (32 to 120°F). Therefore, postpone the test if the temperature is low.
·*2: This inspection can be judged correctly only if the air inlet temperature is within a range of 25 to 35°C (77 to 95°F). Therefore, postpone the test if the temperature is out of range.
| Result | Amount of Refrigerant | Corrective Action |
|---|---|---|
| Refrigerant shortage | Insufficient | 1.
Check for refrigerant leaks using a gas leak detector, and repair if necessary. 2.
Evacuate the air conditioning system and charge it with the appropriate volume of new or purified refrigerant. |
| Refrigerant correct | Correct | - |
| Refrigerant incorrect | Incorrect | Confirm check condition and carry out again |
