Tire And Wheel. Dtc C2111/11 Transmitter Id1 Operation Stop

The tire pressure monitor valve sub-assembly stops transmitting signals when receiving specific signals. The ECU stores the DTC when the tire pressure monitor valve sub-assembly receives the signals for some reason, and stops transmitting signals. As this is not a system malfunction, the DTC is erased when signal transmission is resumed.

HINT:

The radio wave is stopped at assembly plant, because the strength of the radio wave emitting from the tire pressure sensing transmitter does not comply with the Japan Wireless Telegraphy Act.

DTC No.	DTC Detecting Condition	Trouble Area
C2111/11 C2112/12 C2113/13 C2114/14	When any signal similar to the stop signal is received for some reason, this DTC will be output.	Tire pressure monitor valve sub-assembly Tire pressure monitor receiver assembly Tire select switch Tire pressure monitor ECU Wire harness

HINT:

It is necessary to perform the procedure to identify the tire pressure monitor valve sub-assembly that is malfunctioning because it cannot be identified by the output DTC.

INSPECTION PROCEDURE

NOTICE:

It is necessary to register an ID code after replacing the tire pressure monitor valve sub-assembly and/or the tire pressure monitor ECU (Click here).

HINT:

Set the tire pressure to the specified value. Ensure the tire pressure warning switch is set to "MAIN".

1.PERFORM FORCED TRANSMISSION OF TRANSMITTER ID OF 4 WHEELS

Remove the valve cores of the wheels to rapidly reduce the pressure of 4 tires to 120 kPa (1.2 kgf/cm², 17 psi).
HINT:
The transmitter ID can be forcibly transmitted by rapidly reducing tire pressure.
