Inspection
1.
Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals.
2.
Inspect the voltage value whether it is sufficient to be regular value or not.
Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA]
3.
Replacement
1.
Disconnect the negative (-) battery terminal.
2.
Recover the refrigerant with a recovery/ recycling/ charging station.
3.
When the engine is cool, drain the engine coolant from the radiator.
