Method for managing a thermodynamic device for a motor vehicle, system, program, recording medium and associated vehicle

A method for managing a thermodynamic device for a motor vehicle including a heat transfer fluid circuit, the method comprising:

• an initial verification in which a functional status or a defective status for the heat transfer fluid circuit is detected as a function of a first measurement of pressure of a heat transfer fluid in the heat transfer fluid circuit and a comparison thereof against a first threshold;
• and
• after the initial verification during which a defective status has been detected, a confirmation of confirming the defective status, during which a further verification is carried out by performing a second measurement of the pressure and comparing same against a second threshold.

A system for a vehicle of the motor vehicle type, comprising:

• a thermodynamic device comprising a heat transfer fluid circuit and a verification element configured to detect a functional status or a defective status of the heat transfer fluid circuit;
• and
• a confirmation element configured to confirm a defective status once the verification element has detected the defective status.
