Trouble Judgment

ETACS-ECU sends the DTC (U code) detection permission or prohibition signal to each ECU connected to the CAN bus line. If the combination meter cannot receive the DTC (U code) detection permission or prohibition signal for 5 seconds after turning the ignition switch to ON position, DTC U1190 will be set.

If the vehicle information data is not registered to the HUD, the HUD sets DTC U1195.
