Abstract
A secure communication method between a vehicle-mounted diagnostic device and a mobile terminal of a user includes the device broadcasting a paging message, inviting at least one mobile terminal to send a pairing request to the vehicle-mounted device. In response to a pairing request from a mobile terminal, an inquiry signal is sent to the mobile terminal inquiring as to a pairing mode required. One of several pairing modes can be selected, each pairing mode corresponding to a preset pairing password and at least one vehicle-mounted system accessible under the pairing mode. Upon matching the pairing password from the mobile terminal with a device-stored preset pairing password corresponding to the selected pairing mode, a wireless connection between the vehicle-mounted device and the mobile terminal is made, allowing the mobile terminal to access the at least one vehicle-mounted system accessible under the selected pairing mode.
