HwTest Running the test with an external test plug

Description

The function starts a hardware test with an external test plug. This test checks the operation of CAN drivers, KL line drivers and the operation of the switch.

This test cannot be started when the adapter is connected to the car, as the test gives test signals to the output contacts of the OBDII connector. This can block the vehicle’s CAN bus.
