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, this DTC is stored.

DTC No. Detection Item DTC Detection Condition Trouble Area Note
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 -

CAUTION / NOTICE / HINT

Note


  • When replacing the tire pressure warning ECU and receiver, first use the GTS to record all of the current IDs and registered tires with transmitters (4 or 5 tires) of the tire pressure warning valve and transmitter registered to the tire pressure warning ECU and receiver.

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

PROCEDURE


  1. CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES)


    1. Turn the power switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the power switch on (IG).

    4. Turn the GTS on.

    5. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

    6. Check the values by referring to the table below.

      Tech Tips


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

      • The wheel position cannot be determined from ID1 through ID4 on the Data List.

      • When an "ID Tire Inflation Pressure" value has not 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 value.
