DESCRIPTION








The tire pressure monitor valve sub-assembly constantly sends radio waves to the tire pressure monitor ECU. If the battery for the tire pressure monitor valve sub-assembly is depleted, or if the tire pressure antenna is defective or comes off, a DTC will be output. DTCs C2121/21 to C2125/25 and C2131/31 to C2135/35 can only be deleted by the tester. DTCs C2181/81 to C2185/85 can be deleted when the transmitter sends a forced 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.

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.
