How To Proceed With Troubleshooting
CAUTION / NOTICE / HINT
HINT:
- Use the following procedure to troubleshoot the tire pressure warning system.
- Make sure that the wireless door lock control system has exited diagnostic mode before performing the following procedure.
- *: Use the GTS.
PROCEDURE
| 1. | Toyota Prius Vehicle BROUGHT TO WORKSHOP |
|
| 2. | CUSTOMER PROBLEM ANALYSIS |
(a) Interview the customer to confirm the problem.
HINT:
It is important to collect as much specific information as possible from the customer to allow for a quick repair.
|
| 3. | ADJUST TIRE PRESSURE* |
(a) Using the GTS, display the Data List.
(b) Set the pressure of each tire to the specified value.
NOTICE:
Refer to the link as the procedure for adjusting the tire pressures differs depending on the temperature of the tires.
Click here
(c) Display "ID Tire Inflation Pressure" in the Data List and check that the tire pressure values match the adjusted pressure amount.
HINT:
It may take a few minutes until the values are displayed.
(d) Perform initialization.
Click here
HINT:
- The warning threshold value changes depending on the driving conditions during initialization. As a result, the tire pressure warning light may not turn off even if the tire pressure is adjusted to the specified pressure.
-
The tire pressure warning system illuminates the tire pressure warning light to warn the driver when any of the following conditions are met:
- The tire pressure drops to approximately 75% or less of the tire pressure set when the system was initialized.
-
The tire pressure drastically decreases (approximately 20 kPa (0.2 kgf/cm2, 2.9 psi) or more within several minutes) to approximately 75% or less of the tire pressure* when the tires are warmed.
*: If initialization is performed and the Toyota Prius vehicle is driven for a certain period of time, the tire pressure set during system initialization is adjusted and set to the tire pressure when the tires are warmed from the driving conditions.
HINT:
The tire pressure warning pressure (pressure at which the tire pressure warning light is illuminated) cannot be set to approximately 75% or less of a specified tire pressure value.
NOTICE:
If the tire pressure is decreased approximately 20 kPa (0.2 kgf/cm2, 2.9 psi) or more in order to adjust the tire pressure, even if the adjusted tire pressure is 80% or more than the tire pressure set during system initialization, the tire pressure warning light may illuminate if the tire pressure drops below 75% of the tire pressure set when the tires are warmed. In this case, perform initialization again.

Operation Check
OPERATION CHECK
CHECK TIRE PRESSURE WARNING SYSTEM FUNCTION
(a) Using the Data List, check that the current tire pressure is normal.
Click here
(1) Slowly reduce the tire pressure of the front or rear tires and check that the tire pressure on the Data List changes.
(2) Further reduce the tire pressure and check that the warning light illuminates.
(b) After reducing the tire pressure, set the tire pressure to the specified value.

Diagnosis System
DIAGNOSIS SYSTEM
CHECK WARNING LIGHT
NOTICE:
- When there is a problem with the tire pressure warning system, the tire pressure warning light blinks at 0.5 second intervals, and illuminates after 1 minute.
- When the malfunction has been corrected, the tire pressure warning light goes off.
- When the tire pressure warning light illuminates, immediately check the tire pressure of the tires and adjust them to the specified value.
-
After the power switch is turned to ON (IG), the tire pressure warning light illuminates for 3 seconds and then goes off. If the warning light does not illuminate for 3 seconds, proceed to the troubleshooting for the tire pressure warning light circuit.
Click here
(a) Turn the power switch to ON (IG).
| *1 | Tire Pressure Warning Light |
(b) Check that the tire pressure warning light illuminates for 3 seconds.
WHAT TO CONSIDER WHEN TIRE PRESSURE WARNING LIGHT ILLUMINATES
(a) When the tire pressure warning light does not go off, or when it illuminates during driving, check the tire pressure. If the tire pressure warning light illuminates within several hours after adjusting the tire pressure, a tire may have a slow air leak.
(b) The system is disabled under the following conditions (when the condition returns to normal, the system will work properly).
(1) When all of the tire and wheel assemblies that have tire pressure warning valve and transmitters registered with the tire pressure warning ECU and receiver have not been installed.
(2) When all of the transmitter ID codes are not registered with the tire pressure warning ECU and receiver.
(3) When the tire pressure warning valve and transmitter battery is depleted.
(c) The system may be disabled under the following conditions (when the condition returns to normal, the system will work properly).
(1) When electric devices or facilities using similar radio frequencies are nearby.
(2) When a wireless device or other equipment operating at a similar frequency is in use in the Toyota Prius vehicle.
(3) When a window tint that affects radio wave signals is installed.
(4) When there is a lot of snow or ice on the vehicle, in particular, around the wheels or wheel housing.
(5) When non-genuine wheels are used.
(6) When tire chains are used.
(7) When aftermarket tire repair sealant is used.
CAUTION:
After use of tire repair sealant, replacement of the tire pressure warning valve and transmitter is required to ensure normal system operation. (Normal system operation cannot be ensured by only repairing or replacing the tire.)

DATA LIST / ACTIVE TEST
READ DATA LIST
NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
HINT:
Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
(a) According to the display on the GTS, read the Data List.

Tire Pressure Monitor Transmitter ID 1 Missing Message (C214187-C214487)
DESCRIPTION
The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressure of each wheel. The measured values are transmitted to the tire pressure warning ECU and receiver in the vehicle as radio waves. The ECU compares the measured tire pressure values with the tire pressure threshold. When the measured tire pressure value is less than this threshold, the warning light in the combination meter assembly illuminates.
The tire pressure warning valve and transmitters constantly send radio waves to the tire pressure warning ECU and receiver.
Under the conditions below, the tire pressure warning ECU and receiver is unable to receive the signals from the tire pressure warning valve and transmitters, and a DTC is stored.
- Facilities or devices that use similar radio frequencies are located in the vicinity of the Toyota Prius vehicle.
- Devices using similar radio frequencies are used in the vehicle.
- The ID of a tire pressure warning valve and transmitter is mistyped during registration.
- A tire, wheel and/or transmitter from a different vehicle is installed.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
- 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
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.

(2) Devices using similar radio frequencies are used in the vehicle.
HINT:
Radio transmissions may be interrupted due to the surroundings or devices installed by the user.
