1. ECM - Engine Control Module
2. TCM - Transmission Control Moule
3. PCM - Powertrain Control Module - combination of Engine and Transmission
4. BCM - Body Control Module
5. EBCM - Electronic Brake control Module
6. EBTCM - Electronic Brake And Traction Control Module
7. SDM - Sensing and Diagnostics Modules
and so on... as of now... average of 24 modules meron ang mga GM Vehicles..
And of course pati na rin yung ibang mga Car Makers..
Dahil nga, ginagawang standard na yan ng SAE..
Different car manufacturers uses different designs of scan tool..
Im not sure pero sa toyota yata, intelligent tester yung tawag sa scan tool nila...
