| DTC Code | DTC Name |
|---|---|
| C2171/71 | Transmitter ID not Registered |
DESCRIPTION
The IDs of each tire pressure warning valve and transmitter are registered to the tire pressure warning ECU and receiver.
When the ECU detects that a transmitter ID code is not registered in the ECU, this DTC is stored.
