General Procedures Special Tool(s) | Gas Charge Set 49 C061 0A0B | | Gas Leak Tester 49 C061 013 | Refrigerant System Performance Test | -
Inspect the refrigerant pressure. See Refrigerant Pressure Check. | | -
Place a dry-bulb thermometer in the driver-side center ventilator outlet. | | -
Start the engine and after it is warmed up, run it at a constant 1,500 rpm. | | -
Set the fan speed to MAX HI. | | -
Set the temperature control to MAX COLD. | | -
Close all the doors and windows. | | -
Wait until the air conditioner output temperature stabilizes. - The A/C compressor repeatedly turns on and off at regular intervals.
| | -
After the blower air is stabilized, read the dry-bulb thermometer. | | -
Verify the ambient temperature. | | -
Verify that the temperature reading is in the shaded zone. - If the there is any malfunction, inspect the refrigerant system according to the troubleshooting chart.
| Refrigerant Pressure Check | -
Install the SSTs (49 C061 0A0B). | | -
Start the engine and after it is warmed up, run it at a constant 1,500 rpm. | | -
Set the fan speed MAX HI. | | -
Set the temperature control to MAX COLD. | | -
Close all the doors and all the windows. | | -
Measure the ambient temperature and high- and low- pressure side reading of the SST (49 C061 001A). | | -
Verify that the intersection of the pressure reading of the SST (49 C061 001A) and ambient temperature is in the shaded zone. - If there is any malfunction, inspect the refrigerant system according to the troubleshooting chart.
| Leak Test | -
Inspect for leakage using the SST (49 C061 013). - If there is no leakage, go to Step 3.
- If leakage is found at a loose joint, tighten the joint, then go to next step.
| | -
Inspect for leakage again. - If there is no leakage after tightening the joint, go to next step.
- If there is still leakage at the same joint, discharge the refrigerant and then repair the joint. Repeat the charging procedure from evacuation.
For additional information, refer to: Air Conditioning (A/C) System Recovery, Evacuation and Charging (412-00 Climate Control System - General Information, General Procedures). | | -
Disconnect the SSTs (49 C061 006A, 49 C061 007) from the charging valves. | | -
Install the caps to the charging valves. | |
