Test Dental ignition module 33400-72co

Good day,

I have an apparent breakdown in the ignition module of a Swift 93 Suzuki which brings the ignition module is a dense 33400-72co of 4 pins- as can be seen in the figure below there are specified the terminals but I have no idea how to try it.



Can anyone give me a hand with the method or way of trying this module?

Thank you very much in advance.
