DESCRIPTION
The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressure of each wheel. The measured values are transmitted to the tire pressure warning ECU and receiver in the vehicle as radio waves. The ECU compares the measured tire pressure values with the tire pressure threshold. When the measured tire pressure value is less than this threshold, the warning light in the combination meter assembly illuminates.
The tire pressure warning valve and transmitters constantly send radio waves to the tire pressure warning ECU and receiver.
Under the conditions below, the tire pressure warning ECU and receiver is unable to receive the signals from the tire pressure warning valve and transmitters, and a DTC is stored.
- Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.
- Devices using similar radio frequencies are used in the vehicle.
- The ID of a tire pressure warning valve and transmitter is mistyped during registration.
- A tire, wheel and/or transmitter from a different vehicle is installed.
HINT:
When no transmitter ID is received from a tire pressure warning valve and transmitter for 20 minutes or more while the vehicle speed is more than 40 km/h (25 mph), or no transmitter ID is received from all of the tire pressure warning valve and transmitters for 20 minutes or more, DTCs from C2121 to C2124 (C2125: w/ Full Size Spare Tire) are stored.
DTCs C2121 to C2124 (C2125: w/ Full Size Spare Tire) can only be cleared by using the Techstream. DTCs C2181 to C2184 (C2185: w/ Full Size Spare Tire) can be cleared when the tire pressure warning valve and transmitter sends a forced transmission signal or test mode ends. DTCs C2181 to C2184 (C2185: w/ Full Size Spare Tire) are output only in test mode.

NOTICE:
-
w/ ID Switching Function:
(Main) is displayed on the DTC screen for the DTCs even when the 2nd set of tires is selected.
- When DTCs C2121 to C2124 (C2125: w/ Full Size Spare Tire) are set, DTC C2179 may be set simultaneously. In such cases, troubleshoot DTCs C2121 to C2124 (C2125: w/ Full Size Spare Tire) first, then troubleshoot DTC C2179.
- If the Techstream is used to display the Data List for 10 minutes or more, the tire pressure warning ECU stores DTCs C2121 to C2124 (C2125: w/ Full Size Spare Tire). If these DTCs are stored, clear the DTCs using the Techstream.
-
w/o Full Size Spare Tire:
If any DTC from C2121 to C2124 is output, clear the DTCs or drive the vehicle at 40 km/h (25 mph) for 1 minute or more after repairing the malfunctions.
-
w/ Full Size Spare Tire:
If any DTC from C2121 to C2125 is output, clear the DTCs after repairing the malfunctions.
HINT:
It is necessary to perform the following procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because it cannot be identified by the output DTC.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
- When replacing the tire pressure warning ECU and receiver or tire pressure warning valve and transmitter, read the transmitter IDs and number of the transmitters (4 or 5) stored in the old ECU using the Techstream and write them down before removal.
-
It is necessary to perform initialization

(h) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kg/cm2, 5.8 psi) within 30 seconds. If the "ID Tire Inflation Pressure" value displayed on the Techstream does not change, the tire pressure warning valve and transmitter corresponding to the unchanged "ID Tire Inflation Pressure" value was the cause of the output DTC.
HINT:
- Identify the malfunctioning tire pressure warning valve and transmitter by repeatedly decreasing the tire pressure for each tire.
- Record which "ID Tire Inflation Pressure" value corresponds to each tire.
(i) Check the Data List.
NOTICE:
- It may take a few minutes until the values are displayed.
- When an "ID Tire Inflation Pressure" value has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270 degrees. Then rapidly release the tire pressure and recheck the value.
- Record the transmitter IDs and positions of transmitters that are normal.
(j) After confirming that the "ID Tire Inflation Pressure" value for one tire has changed, repeat this procedure for each tire. Identify the transmitter that corresponds to the DTC.
