00-15)

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

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.
