The pressures with the ignition turned off meet the specifications.
-- Start the engine.
-- Bring the engine speed up to 2000 RPM.
-- Observe the pressure gauge of the service station.
The switch pressures for refrigerant circuit switches are vehicle-specific.
The connection with valve for low-pressure switch or at evaporator is only to be used for vehicles with no service connection on low-pressure side and inaccessible connection at compressor or accumulator (measurement accuracy). Only applies to specific vehicles. Refer to Refrigerant Circuit .
