How do I test body control module and is it hard to do..
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.
To determine if the seat motor or control module is faulty in your Mercedes CLK, first check if the seat moves at all when using the controls. If there’s no response, inspect the fuse associated with the seat functions. If the fuse is intact, you can test the seat motor by applying direct power to it; if it operates, the control module may be the issue. Additionally, using a diagnostic tool can help identify any error codes related to the seat control module.
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.
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.

Depending on what circuit you are testing, you can toast the ECM (Engine Control Module).
