TIRE PRESSURE WARNING SYSTEM, Diagnostic DTC:C2171/71

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, a DTC is stored.

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

Note

w/ ID Switching Function:

Even when the 2nd set of tires is selected via the ID switching function, (Main) is displayed on the DTC screen for the DTCs.

CAUTION / NOTICE / HINT

Note


  • When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.

  • It is necessary to perform initialization (Click here ) after registration Click here of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.

PROCEDURE


  1. CHECK REGISTRATION CONDITION (REGISTERED ID CODES)


    1. Turn the ignition switch off.

    2. Connect the GTS to the DLC3.

      Tech Tips


      • *: It may take a few minutes until the values are displayed.

      • When no "ID Tire Inflation Pressure" data has changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270 degrees. Then rapidly release the tire pressure and recheck the data.
