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, this 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
NOTICE:
w/ ID Switching Function:
(Main) is displayed on the DTC screen for the DTCs even when the 2nd set of tires is selected.

INSPECTION PROCEDURE

NOTICE:
  1. 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.
  2. It is necessary to perform initialization (LandCruiser RM000000XMZ0AOX.html) after registration (LandCruiser RM000000XN10DCX.html) of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.
1.CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES)

  1. Turn the ignition switch off.

  1. Connect the GTS to the DLC3.

  1. Turn the ignition switch ON.

  1. Turn the GTS on.

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

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

    HINT:
    1. *1: Displayed only when the ID No. is not registered.
    2. *2: w/ Spare Tire
    3. The wheel position cannot be determined from ID1 through ID4 or ID1 through ID5 (w/ Spare Tire) on the Data List.
    OK:
    The registered transmitter ID codes are displayed on the GTS.

4.CONFIRM TIRE INFLATION PRESSURE (DATA LIST)

  1. Turn the ignition switch off.

  1. Connect the GTS to the DLC3.

  1. Turn the ignition switch ON.

  1. Turn the GTS on.

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

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