DTC U1412: Implausible Vehicle Speed Signal Received

M14209100150USA0000010000

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
KOS-ECU receives the wheel speed information from ABS-ECU
or ASC-ECU via the CAN-bus line. If KOS-ECU cannot receive
the information about the 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 KOS-ECU

ECU.<Refer to GROUP 35B, diagnostic trouble code chart P.
35B-9(vehicles without ASC) or Refer to GROUP 35C,
diagnostic trouble code chart P.35C-11(vehicles with ASC)
>. Then go to Step 4.

STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set.

(1)

Turn the ignition switch to the "LOCK" (OFF) position.

(2)

Turn the ignition switch to the "ON" position.

(3)

Check if the DTC is set.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the diagnostic trouble code U1412 reset?

YES:

Start over at Step 1.

NO:

The procedure is complete.

DTC U1415: Coding not completed/Data fail

M14209100106USA0000010000

｠

If the 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 KOS-ECU sets the DTC
U1415.

KEYLESS OPERATION SYSTEM (KOS)

DIAGNOSIS

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

TROUBLESHOOTING HINTS

｠

The CAN bus line may be defective.

｠

The KOS-ECU may be defective.

｠

The ETACS-ECU may be defective.

Code No.U1417 Implausible coding data

M14209100107USA0000010000

｠

If diagnostic trouble code U1417 is set in KOS-ECU,
always diagnose the CAN bus lines. If there is any fault in
the CAN bus lines, an incorrect diagnostic trouble code
may be set. In this case, the set diagnostic trouble code
is not highly reliable.

｠

Before replacing the ECU, ensure that the communication
circuit is normal.

｠

When the diagnostic trouble code U1417 is set in KOS-
ECU, the diagnostic trouble code may also be set in
ETACS-ECU. When the diagnostic trouble code is set in
ETACS-ECU, carry out the diagnosis of the diagnostic
trouble code for ETACS-ECU first.

CIRCUIT OPERATION
KOS-ECU receives the vehicle information stored in the ETACS-
ECU via CAN bus lines.

DTC SET CONDITIONS
KOS-ECU communicates with ETACS-ECU via CAN bus lines.
This diagnostic trouble code is set when the vehicle information
received from the ETACS-ECU is invalid.

PROBABLE CAUSES

｠

Malfunction of ETACS-ECU

｠

Engine control module malfunction

｠

ETACS-ECUs have been interchanged between two vehicles.

｠

KOS-ECU malfunction

｠

External noise interference

｠

WCMs have been interchanged between two vehicles.
