DESCRIPTION
The tire pressure warning valve and transmitter constantly sends radio waves to the tire pressure warning ECU.
Under the following conditions, the tire pressure warning antenna and receiver is unable to receive the signals from the tire pressure warning valve and transmitter, and a DTC is output.
^ Areas, 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.
DTCs C2121/21 to C2124/24 can only be deleted by the tester. DTCs C2181/81 to C2184/84 can be deleted when the transmitter sends a forced transmission signal or the test mode ends. DTCs C2181/81 to C2184/84 are output only in the test mode.
HINT: When no signals are received for 60 minutes or more, a DTC is output. It is necessary to perform the procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because it cannot be identified by the output DTC.
