STEP 5. Recheck for diagnostic trouble code.
Check again if the DTC is set to the ETACS-ECU.
(1)
Erase the DTC.
(2)
Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.
(3)
Check if DTC is set.
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
Q:Is the DTC set?
YES:
Replace the ETACS-ECU.
NO:
The trouble can be an intermittent malfunction such
as a poor connection or open circuit in the CAN bus lines
between the SRS-ECU and the ETACS-ECU. (Refer to GROUP 00,
How to Cope with Intermittent Malfunction P.00-15)
DTC U0154: Occupant classification-ECU CAN timeout
M15410600077USA0000010000
⦆
If DTC U0154 is set to the ETACS-ECU, always
diagnose the CAN bus line.
⦆
Before replacing the ECU, ensure that the
communication circuit is normal.
TROUBLE JUDGMENT
If the signal from occupant classification-ECU cannot
be received, the ETACS-ECU sets DTC U0154.
JUDGMENT CRITERIA
After the following statuses continue to be true for 5
seconds, if the communication with the occupant
classification-ECU cannot be established for 0.6
second or more, the ETACS-ECU determines that a
problem has occurred.
⦆
No abnormality is present to the network.
⦆
Ignition switch is in the ON position.
⦆
No abnormality is present to the power supply fuse,
or the odometer value is at 80.5 km (50.0 miles) or
more.
⦆
ETACS-ECU system voltage is at 10-16 volts.
TROUBLESHOOTING HINTS
⦆
The occupant classification-ECU may be defective.
⦆
The ETACS-ECU may be defective.
⦆
The CAN bus may be defective.
