DTC C2115 TRANSMITTER ID5 OPERATION STOP

CIRCUIT DESCRIPTION

DTC Detecting Condition:

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.

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.
