ETACS-ECU sends the DTC (U code) detection permission or prohibition signal to each ECU connected to the CAN bus line. If the radio and CD player cannot receive the DTC (U code) detection permission or prohibition signal for 5 seconds after turning the electric motor switch to ON position, DTC U1190 will be stored.
