DTC C1900: No Registration

M14209200059USA0000010000

WIRELESS CONTROL MODULE (WCM)

42C-35

DIAGNOSIS

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 for the TPMS transmitter is
not  stored  in  WCM,  this  code  is  set.  Also  when  the  forced
termination  is  made  while  one  or  more  wheels  are  registered
with the ID registration mode, the ID information inside WCM is
erased, and 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 WCM

DTC C1901: Vehicle Speed Information Abnormality

M14209200060USA0000010000

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. If the WCM receives information
from  the  ABS-ECU  or  ASC-ECU  indicating  the  wheel  is  not
currently rotating and the TPMS transmitter sends information
indicating the wheel is currently rotating, 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 WCM

｠

Malfunction of ABS-ECU or ASC-ECU

Q:Is the diagnostic trouble code C1901 set?

YES:

 Go to Step 3.

NO:

 The procedure is complete.

STEP 3. Check for other diagnostic trouble code.
Check  if  the  diagnostic  trouble  code  is  set  from  ABS-ECU  or
ASC-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)>

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 WCM and register the ID codes. (Refer to P.
42C-8.) 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.

diagnostic trouble code chart P.35C-11(vehicles with ASC)
>. Then go to Step 4.

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.
