You need to disconnect it from the circuit before you test it for resistance.
check fuse/relay then if not that idle air control valve 'throttle control sensor' map sensor' electronic control module' test them all.
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
you dont
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.

Need to check the body control module, And all fuses with a test light.
Depending on what circuit you are testing, you can toast the ECM (Engine Control Module).
Many autopart stores have a machine to test it. The machines use a universal adapter to hook into the ignition control module. The ignition control module is in the distributor. If you mean the part that contains the ignition coil, when mine went bad I probed it with an ohmeter and then asked the parts store if I could test the resistances in a new coil before I bought it. Since the resistances of certain terminals weren't even close, I knew I had a bad coil.
