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.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | Note |
---|---|---|---|---|
C2171 | Transmitter ID not Registered (Main) | Transmitter ID code is not registered. (When an ID code is unregistered for 3 minutes or more) | Tire pressure warning ECU and receiver | - |
