DTC U1412: Implausible Vehicle Speed Signal Received

M14209200067USA0000010000

If there is any problem in the CAN bus lines, an incorrect
diagnostic trouble code may be set. Prior to this diagnosis,
diagnose the CAN bus lines. (Refer to GROUP 54D, Trouble
code diagnosis P.54D-17).

TPMS DTC SET CONDITION
WCM receives the wheel speed information from ABS-ECU or
ASC-ECU via the CAN-bus line. When WCM cannot receive the
information about wheel speed sensor from ABS-ECU or ASC-
ECU, this code is set.

TROUBLESHOOTING HINTS
The most likely causes for this DTC to set are:

｠

Damaged wiring harness and connector

｠

Malfunction of ABS-ECU or ASC-ECU

｠

Malfunction of WCM

DTC U1415: Coding not completed/Data fail

M14209200030USA0000010000

｠

If DTC U1415 is set, diagnose the CAN bus lines.

｠

When replacing the ECU, always check that the
communication circuit is normal.

DIAGNOSTIC FUNCTION
If the vehicle information data is not registered to the
combination meter, the WCM sets DTC U1415.

JUDGMENT CRITERIA
With the global coding counter value "0," if all the
global coding data (vehicle information) are not
stored, the WCM determines that a problem has
occurred.

TROUBLESHOOTING HINTS

｠

The CAN bus line may be defective.

｠

The WCM may be defective.

｠
