Abstract

A wireless diagnostic module includes a connection port connected to a connector provided in a first appliance; a first signal transceiving unit to transceive a signal corresponding to a first communication protocol by making communication with the first appliance connected through the connection port; a signal converting unit to convert the signal corresponding to the first communication protocol transmitted through the first signal transceiving unit into a signal corresponding to a second communication protocol; and a second signal transceiving unit to transmit the signal corresponding to the second communication protocol, which is converted through the signal converting unit, to a second appliance, wherein the first communication protocol comprises at least one of ISO, KWP, PWM, CAN and VWP supported by the connector provided in the first appliance, and the second communication protocol comprises a wireless communication protocol for wireless communication between the first and second appliances.

Claims

1. A wireless diagnostic module comprising:

a second wireless diagnostic module detachably connected to a connector of a diagnostic equipment,

wherein the first wireless diagnostic module is configured to;

receive a first signal corresponding to a first communication protocol from the OBD connector;

convert the first signal into a second signal corresponding to a second communication protocol;

transmit the second signal to the second wireless diagnostic module;

receive a third signal corresponding to the second communication protocol from the second wireless diagnostic module;

convert the third signal into a fourth signal corresponding to the first communication protocol; and

output the fourth signal via the OBD connector,

wherein the second wireless diagnostic module is configured to;

receive the fourth signal via the connector of the diagnostic equipment;

convert the fourth signal into the third signal;

transmit the third signal to the first wireless diagnostic module;

receive the second signal via the connector of the diagnostic equipment;
