Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - TIRE PRESSURE MONITORING
CHECK FREQUENCY RECEIVING CONDITION
CONFIRM TIRE INFLATION PRESSURE (DATA LIST)
DTC C2177/77 Initialization not Completed
DESCRIPTION
Initialization is necessary if one of the following occurs:
The tire pressure warning ECU and receiver is replaced.
A tire pressure warning valve and transmitter is replaced.
Tires with a different tire standard pressure are installed.
The tires are rotated.
A new vehicle is delivered.
| DTC No. | DTC Detection Condition | Trouble Area |
| C2177/77 | All conditions below are met: During initialization Tire pressure warning valve and transmitter is not in stop mode. Signal is not received from tire pressure warning valve and transmitter for 10 minutes or more. Vehicle speed is more than 37 km/h (23 mph) for a total of 10 minutes. | Tire pressure warning valve and transmitter Tire pressure warning ECU and receiver |
WIRING DIAGRAM
INSPECTION PROCEDURE
- NOTICE:
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 () after registration () 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.CHECK FREQUENCY RECEIVING CONDITION |
Check that the vehicle is not located in an area such as described below:
Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.
- HINT:
- If the vehicle is located in an area such as the one described above, the tire pressure warning light may come on after blinking 1 minute only in a particular area due to interfering radio frequencies.
Devices using similar radio frequencies are used in the vehicle.
- OK:
- Facilities or devices that use similar radio frequencies are not located in the vicinity of the vehicle.
- HINT:
- Radio transmissions may be interrupted due to the surroundings, or devices installed by the user.

| 3.CONFIRM TIRE INFLATION PRESSURE (DATA LIST) |
Turn the engine switch off.
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
Check the values by referring to the table below.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| ID 1 Tire Inflation Pressure | ID1 tire inflation pressure/ min.: Absolute pressure (abs)/ 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (gauge)/ 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure (abs)/ 480 kPa (4.9 kgf/cm2, 70 psi), Relative pressure (gauge)/ 380 kPa (3.9 kgf/cm2, 55 psi) | Actual tire inflation pressure | If N/A is displayed, data has not been received.* |
| ID 2 Tire Inflation Pressure | ID2 tire inflation pressure/ min.: Absolute pressure (abs)/ 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (gauge)/ 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure (abs)/ 480 kPa (4.9 kgf/cm2, 70 psi), Relative pressure (gauge)/ 380 kPa (3.9 kgf/cm2, 55 psi) | Actual tire inflation pressure | If N/A is displayed, data has not been received.* |
| ID 3 Tire Inflation Pressure | ID3 tire inflation pressure/ min.: Absolute pressure (abs)/ 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (gauge)/ 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure (abs)/ 480 kPa (4.9 kgf/cm2, 70 psi), Relative pressure (gauge)/ 380 kPa (3.9 kgf/cm2, 55 psi) | Actual tire inflation pressure | If N/A is displayed, data has not been received.* |
| ID 4 Tire Inflation Pressure | ID4 tire inflation pressure/ min.: Absolute pressure (abs)/ 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (gauge)/ 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure (abs)/ 480 kPa (4.9 kgf/cm2, 70 psi), Relative pressure (gauge)/ 380 kPa (3.9 kgf/cm2, 55 psi) | Actual tire inflation pressure | If N/A is displayed, data has not been received.* |
| ID 5 Tire Inflation Pressure | ID5 tire inflation pressure/ min.: Absolute pressure (abs)/ 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (gauge)/ 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure (abs)/ 480 kPa (4.9 kgf/cm2, 70 psi), Relative pressure (gauge)/ 380 kPa (3.9 kgf/cm2, 55 psi) | Actual tire inflation pressure | If N/A is displayed, data has not been received.* |
- HINT:
*: 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.
The wheel position cannot be determined from ID1 through ID5 on the Data List.
- Result:
Result Proceed to All tire pressure readings are equal to specified values. A Tire pressure values are not displayed. B
