DIAGNOSIS
DIAGNOSTIC FUNCTION
When the signals from occupant classification-ECU
cannot be received, the combination meter sets DTC
U0154.
JUDGMENT 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 communications
with occupant classification-ECU 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.
