A system for identifying an electronic device connected to a communication network that has XCP enabled. The system includes, in one example, a communication network, a plurality of electronic devices, and a testing device. The testing device includes an electronic processor. The electronic processor is configured to send a XCP connect message via the communication network. When a first response is received in response to the first XCP connect message, the electronic processor determines that one or more of the plurality of electronic devices have XCP enabled. For each electronic device included in the plurality of electronic devices, the electronic processor is configured to send a reset command to the electronic device, resend the XCP connect message to the plurality of electronic devices, and, when a second response is not received in response to the resent XCP connect message, determine that the electronic device has XCP enabled.
