DTC 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, a DTC is stored.

DTC No.
DTC Detection Condition
Trouble Area
C2171/71
Transmitter ID code is not registered. (When an ID code is unregistered for 3 minutes or more)
Tire pressure warning ECU and receiver

INSPECTION PROCEDURE

NOTICE:
  1. When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the Techstream and write them down before removal.
  2. It is necessary to perform initialization (YARIS_NCP93 RM000000XMZ073X.html) after registration (YARIS_NCP93 RM000000XN107WX.html) of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.
  3. When replacing the tire pressure warning ECU and receiver on vehicles equipped with the wireless door lock control system, be sure to perform Registration of Recognition Code to register the transmitter IDs after ECU replacement (YARIS_NCP93 RM0000023D302UX.html).
1.CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES)

  1. Turn the ignition switch off.

  1. Connect the Techstream to the DLC3.
