  • Machine tamper detection
    Patent number: 10960850
    Abstract: A tamper detection system is disclosed. The tamper detection system may include an electronic control module (ECM) of a machine and a tamper detection module. The tamper detection module may detect, while the machine is powered off, an opening of a switch that is associated with a component of the machine. The opening of the switch may indicate tampering with the component of the machine. The tamper detection module may set, while the machine is powered off, a state of a latch based on detecting the opening of the switch. The state, while set, may indicate that the switch was opened. The tamper detection module may cause, when the machine is powered on, the ECM to provide an indication that tampering with the component of the machine has occurred based on the state.
