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 transaxle control module and the ETACS-ECU.
(Refer to GROUP 00, How to Cope with Intermittent
Malfunction P.00-15)

DTC U0114: AWD-ECU CAN timeout

M15410600053USA0000010000

｠

If DTC U0114 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 AWD-ECU cannot be received, the
ETACS-ECU sets DTC U0114.

JUDGMENT CRITERIA
After the following statuses continue to be true for 5
seconds,  if  the  communication  with  the  AWD-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 AWD-ECU may be defective.

｠

The ETACS-ECU may be defective.

｠

The CAN bus may be defective.
