DTC C2181 TRANSMITTER ID1 NOT RECEIVED (TEST DIAGNOSIS)

CIRCUIT DESCRIPTION

DTC Detecting Condition:

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 C2125/25 can only be deleted by the tester. DTCs C2181/81 to C2185/85 can be deleted when the transmitter sends a force transmission signal or the test mode ends. DTCs C2181/81 to C2185/85 are output only in the test mode.

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.
