A serial communication system for a vehicle including an interface circuitry that generates a triggering signal, and a controller circuitry with an input block, an output block, a controller connected to the input block and the output block, the controller being configured to function in a normal mode or in a diagnostic mode, wherein in the normal mode the controller receives a sensing signal and provides an actuating signal based on the sensing signal, and in the diagnostic mode the input block transmits an input communication signal from the interface circuitry and the output block transmits an output communication signal from the controller to the interface circuitry, and a Diagnostic mode detector connected to the input block and configured to receive the triggering signal detect the triggering signal, and switch the controller from the normal mode to the diagnostic mode when the triggering signal is detected.
