Seems like everyone's advice for factory alarm problems is to unplug the two connectors to the brain under the passenger footwell. I have a new 93 190E and am slowly fixing all the little things that have been neglected for years by the previous owner. While replacing the cruise control amp module, I noticed that my alarm brain was unplugged. I plugged the two connectors back in and the ticking started and lights flashed. Does the brain itself ever go bad? I have searched the forum and can not find anything on this subject.
