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

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.
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.
(1)
Start the engine and drive the vehicle at 5 km/h or more.
