DESCRIPTION
The tire pressure monitor valve sub-assembly constantly sends radio waves to the tire pressure monitor receiver assembly. If the battery for the tire pressure monitor valve sub-assembly is depleted, or if the tire pressure monitor receiver assembly is defective or comes off, the DTC will be output. DTCs C2121/21 to C2124/24 and C2131/31 to C2134/34 can only be deleted by the tester. DTCs C2181/81 to C2184/84 can be deleted when the transmitter sends a force transmission signal or the test mode ends. DTCs C2181/81 to C2184/84 are output only in the test mode.
DTC DETECTION CONDITION:
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.
WIRING DIAGRAM:
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.
HINT: Set the tire pressure to the specified value.
