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 ABS-ECU or ASC-ECU and the ETACS-ECU. (Refer
to GROUP 00, How to Cope with Intermittent Malfunction P.

DTC U0126: Steering wheel sensor CAN timeout

M15410600076USA0000010000

｠

If DTC U0126 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  steering  wheel  sensor  cannot  be
received, the ETACS-ECU sets DTC U0126.

JUDGMENT CRITERIA
After the following statuses continue to be true for 5
seconds, if the communication with the steering wheel
sensor 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 steering wheel sensor may be defective.

｠

The ETACS-ECU may be defective.

｠

The CAN bus may be defective.
