Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Typically when these systems turn off like this it is due to the module trying to conserve voltage. Most of the time it is either due to a bad battery connection, a bad battery, or a failing alternator. All of these need to be checked. Most auto parts stores can test the battery and alternator for you. If all of these are fine then you may have a failing body control module or ignition switch.
