DTC C1900: No Registration

M14209100151USA0000010000

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
When the ID registration information of the TPMS transmitter is
not stored in KOS-ECU, this code is set. If the ID registration
mode  is  terminated  forcibly  after  one  or  more  wheels  are
registered in the ID registration mode, the ID information in the
KOS-ECU is erased, and this diagnostic trouble code is set.

DTC C1901: Vehicle Speed Information Abnormality

M14209100153USA0000010000

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. Although KOS-ECU receives
the information that the wheel is not currently rotated from ABS-
ECU or ASC-ECU, if the TPMS transmitter sends the information
that the wheel is rotated, this code is set.

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

｠

Damaged wiring harness and connector

｠

Malfunction of TPMS transmitter

｠

Malfunction of KOS-ECU

｠

Malfunction of ABS-ECU or ASC-ECU

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

Q:Is the check result normal?

YES:

 Check the registered ID by the transmitter ID check

function, and then check the acceleration value of each
wheel by the transmitter check function. If the value
exceeding 5 g is displayed, replace the relevant TPMS
transmitter and register the ID code. If the value
exceeding 5 g is not displayed for any TPMS transmitter,
replace the KOS-ECU and register the ID codes. (refer
to P.42B-12.) Then go to Step 4.

NO:

 Carry out the troubleshooting for ABS-ECU or ASC-

ECU.<Refer to GROUP 35B, diagnostic trouble code chart P.

STEP 4. Recheck for diagnostic trouble code.

(1)

Start the engine and drive the vehicle at 5 km/h or more.

(2)

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

(3)

Turn the ignition switch to the "ON" position.
