Thank you! I am not looking to replace it. I want to remove all power to see if it will clear a fault in the SKREEM anti-theft module. This seemed to work for "Superstar" in his SKREEM NO MORE thread. I know I can clear it with DRBIII but I don't have access to one and the only option to get one seems to be to rent one. I believe I activated the immobilization when I first started to code my V8 ECU to my car. The ECU is now correctly coded to the car and everything seems to be working properly with no fault codes but the only module I haven't been able to access in the MB STAR Diagnostic system is the anti-theft module.
