DTC U0155: Meter CAN timeout
CAUTION
If DTC U0155 is set in the radio and CD player,
diagnose the CAN main bus line.
CAUTION
Whenever the radio and CD player is replaced,
ensure that the communication circuit is normal.
.
DIAGNOSTIC FUNCTION
When the signals from combination meter cannot be
received, the radio and CD player sets DTC U0155.
.
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 combination meter cannot
be established for 2,500 ms or more, the radio and
CD player determines that a problem has occurred.
.
TROUBLESHOOTING HINTS
