SYSTEMS AND METHODS FOR VEHICLE DIAGNOSTIC TESTER COORDINATION

Method and apparatus are disclosed for coordinating multiple vehicle diagnostic testers. An example vehicle includes communication buses, an electronic control unit (ECU) coupled to one of the communication buses, and a gateway module. The a gateway module is configured to receive a request for communication with the ECU from a first in-vehicle diagnostic (IVD) tester, and responsively prevent communication with a second IVD tester while facilitating communication between the first IVD tester and the ECU.
