You need to disconnect it from the circuit before you test it for resistance.
To test a climate control module, first, use a diagnostic scan tool to check for any trouble codes related to the climate control system. Next, inspect the wiring and connections for any visible damage or corrosion. You can then verify the functionality of the module by checking the operation of the controls and the response of the heating, ventilation, and air conditioning (HVAC) components. Finally, if necessary, perform a bench test of the module to ensure it operates within specifications.
You can check the Mercedes-Benz air conditioning control module with a diagnostic tester. Hook the diagnostic tester to the diagnostic test port.
If by control module you are referring to an ignition module then you need to remove it from the distributor and take it in to a shop for testing ,it requires special equipment for testing.A new module runs from $50-$100 depending on model

Stus are nothing but the replacement for the modules which are subordinate to module under test. These dummy modules use subordinate module's interface & do some data manipulation, Print the verification & Return control to the module under test. e.g Suppose I have 3 modules viz, module1,module2 & module3 & I have to test module 2. Module 2 is ready but module3 is not ready so we will create a dummy module for module3 which is called as stub. Also we can say that Stub's are nothing but the called functions. These are also called as test harness tools.
What does the general control module control
ECM, (Engine Control Module, Electronic Control Module) PCM, (Powertrain Control Module, Power Control Module) ECU, (Engine Control Unit, Electronic Control Unit).
Need to know which control module in question.
To test the ignition control module (ICM) on a Datsun 280ZX, first, ensure the vehicle is turned off and disconnected from the battery. Use a multimeter to check the resistance of the ICM's terminals according to the specifications in the service manual. Additionally, you can perform a functional test by checking for proper voltage output while cranking the engine. If the module fails these tests, it may need to be replaced.
