It is probable that the solenoid relay in question, characterized by its bright green color, is intended for the suspension air compressor. The recommended placement for the installation of the device is in close proximity to, or directly on, the suspension compressor unit. This component is often situated towards the back of the car, frequently found in the trunk area or in close proximity to the spare tire well. Please search for a module that has both air lines and electrical connections. The solenoid relay should be connected to this module. If the item in question cannot be located, it is advisable to consult a repair manual or seek guidance from a qualified technician who specializes in the unique configuration of your car.

Indeed, I have located the control module as previously said. However, I am interested in acquiring knowledge on the appropriate methodology for testing such control module.

In the meantime, my intention is to inflate the bags using an additional battery connected to the compressor, which operates independently from the vehicle, in order to facilitate the movement of the object in question. Subsequently, a decision will be made about whether to retain or sell it.
