Trouble Judgment

With the statuses that the ignition switch is at ON position, system voltage is 10-16 V (data from ETACS-ECU), and there is no malfunction to the power supply fuse (IOD fuse), or odometer value is 80.5 km or more, if the communication with A/C-ECU cannot be established for 2,500 ms or more, the CAN box unit determines that a problem has occurred.
