DTC U0184: Audio CAN timeout
CAUTION
• If DTC U0184 is set, be sure to diagnose the
CAN bus line.
• When replacing the ECU, always check that
the communication circuit is normal.
.
DIAGNOSTIC FUNCTION
When the signals from radio and CD player or CD
changer cannot be received, the combination meter
sets the DTC U0184.
.
JUDGEMENT CRITERIA
With the ignition switch in the ON position, system
voltage between 10
− 16 volts (data from
ETACS-ECU), power supply fuse is OK, or odometer
value is 80.5 km (50 miles) or more, and the commu-
nications with radio and CD player or CD changer
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.
• The radio and CD player or CD changer may be
defective.
DIAGNOSIS
