DTC U0245: Audio visual navigation unit CAN timeout
CAUTION
• If DTC U0245 is set, be sure to diagnose the
CAN bus line.
• When replacing the ECU, always check that
the communication circuit is normal.

When the signals from audio visual navigation unit
cannot be received, the combination meter sets DTC
U0245.
.
JUDGMENT CRITERIA
With the ignition switch in the ON position, system
voltage between 10
− 16 volts (data from
ETACS-ECU), power supply fuse (IOD fuse) is OK,
or odometer value is 80.5 km (50 miles) or more, and
the communications with audio visual navigation unit
cannot be established for 2,500 ms or more, the
combination meter determines that a problem has
occurred.
.
TROUBLESHOOTING HINTS
• The CAN bus line may be defective.
• The combination meter may be defective.
