Methods, systems, and devices manipulate operation of at least one electronic control unit (ECU) connected to a controller area network (CAN) bus. The at least one ECU includes at least one error counter, by counting errors associated with at least one ECU. The manipulating is based on generating and broadcasting via the CAN at least one bit stream destined to at least one ECU, thereby manipulating at least one ECU status, determined by the ECU error counter and querying for its status state.
