DTC C2145/45 Transmitter ID5 Error


DESCRIPTION

The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressures. The measured values are transmitted to the tire pressure warning ECU and receiver in the vehicle as radio waves. The ECU compares the measured air pressure values with the air pressure threshold. When the measured air pressure value is less than this threshold, the warning light in the combination meter illuminates.
When the internal circuit of a tire pressure warning valve and transmitter is malfunctioning, one of these DTCs is output.

DTC No.
DTC Detection Condition
Trouble Area
C2141/41
C2142/42
C2143/43
C2144/44
C2145/45
If an "ERROR" signal is received 3 times consecutively, the tire pressure warning valve and transmitter will be judged as defective and a DTC will be output.
This will happen in situations where the inflation pressure is outside the range 0 to 380 kPa (0 to 3.9 kgf/cm2, 0 to 55 psi), the temperature inside the tire is outside the specified range -40 to 120°C (-40 to 248°F), or an error occurs in the tire pressure warning valve and transmitter or the surrounding area.
  1. Tire pressure warning valve and transmitter
  2. Tire pressure warning ECU and receiver
HINT:
It is necessary to perform the following procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because it cannot be identified by the output DTC.

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 and/or one of the valve and transmitters has been replaced.
1.IDENTIFY TRANSMITTER CORRESPONDING TO DTC

  1. Set the tire pressure to the specified value (LandCruiser RM000003DGS00UX.html).

  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. Display the "ID Tire Inflation Pressure" data for each wheel using the GTS.

  1. Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kg/cm2, 5.8 psi) within 30 seconds. If "ID Tire Inflation Pressure" displayed on the GTS does not change, the tire pressure warning valve and transmitter corresponding to the unchanged "ID Tire Inflation Pressure" data was the cause of the output DTC.

    HINT:
    1. Identify the malfunctioning tire pressure warning valve and transmitter by repeatedly decreasing the tire pressure for each tire.
    2. Record which "ID Tire Inflation Pressure" data corresponds to each tire.

    NOTICE:
    1. It may take a few minutes to display the updated tire pressure data.
    2. When the "ID Tire Inflation Pressure" data 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 data.
    3. Record the transmitter ID of which "ID Tire Inflation Pressure" data corresponds to each tire.

  1. When the "ID Tire inflation Pressure" data has changed, repeat this procedure to identify the tire pressure warning valve and transmitter that corresponds to the DTC.

  1. When all of the "ID Tire Inflation Pressure" data has changed, identify the malfunctioning tire pressure warning valve and transmitter using the recorded ID numbers and output DTCs.
