Title: TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: REGISTRATION; 2020 - 2024 MY Camry HV [09/2019 -        ]

REGISTRATION

PROCEDURE

1. BEFORE REGISTRATION

NOTICE:

  • The transmitter ID is written on the tire pressure warning valve and transmitter. It is not possible to read the transmitter ID after installing the tire onto the wheel. Therefore, make a note of the transmitter ID before installing the tire.
  • Make sure to perform ID registration using the Techstream after replacing the tire pressure warning ECU and receiver.

(a) When replacing the tire pressure warning ECU and receiver:

(1) When replacing the tire pressure warning ECU and receiver, read the transmitter IDs and number of the transmitters (4 or 5) stored in the old ECU using the Techstream and write them down before removal.

(2) If reading the stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning ECU and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valve and transmitters.

(b) When replacing a tire pressure warning valve and transmitter:

(1) Take a note of the 7-digit number (transmitter ID) written on the tire pressure warning valve and transmitter.

*A

for Type A

*B

for Type B

2. REGISTER TRANSMITTER ID (USING TECHSTREAM)

w/ ID Switching Function:

  • Before performing ID registration for the 2nd tire set, make sure that ID registration has been completed for the main tire set.
  • If ID registration for the main tire set has not been completed, it is not possible to perform ID registration for the 2nd tire set.
  • When performing ID registration for the 2nd tire set, make sure that both the main tire set and 2nd tire set are close to the vehicle (within 10 m (32.8 ft.)).

    HINT:

    If the main tire set is not close to the vehicle (within 10 m (32.8 ft.)) when ID registration is performed for the 2nd tire set, DTC C2126 will be stored.

  • Make sure to install the appropriate tire set before performing ID switching.

HINT:

  • The previously registered IDs will be cleared from memory when registration is completed.
  • If the ID registration step is not completed within 300 seconds, ID registration will be canceled.
  • w/ ID Switching Function:

    When performing ID registration for the 2nd tire set, select "2nd Set" on the Techstream.

(a) Set the tire pressure to the specified value.

(g) Perform the procedure displayed on the Techstream.

HINT:

The number of registered tire pressure warning valve and transmitters can only be set to 4 when the value is currently set to 5. The number of registered tire pressure warning valve and transmitters should only be changed from the default value when requested by the customer.

3. CONFIRMATION OF TRANSMITTER ID REGISTRATION (USING TECHSTREAM)

NOTICE:

  • It may take a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121 to C2124 (C2125: w/ Full Size Spare Tire).

    Click here 2020 - 2024 MY Camry HV [09/2019 -        ]; TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: C2121-C2125,C2181-C2185; Transmitter ID 1 not Received (Main)

  • If the transmitter IDs have not been registered, DTC C2171 is stored in the tire pressure warning ECU and receiver after 3 minutes or more.
  • If normal pressure values are displayed, the transmitter IDs have been registered correctly.
  • If the tire pressure values are not displayed after a few minutes, the transmitter IDs may be incorrect or the system may have a malfunction.
  • After all transmitter IDs are registered, DTC C2126 is stored in the tire pressure warning ECU and receiver and the tire pressure warning light blinks for 1 minute and then illuminates. When the tire pressure warning ECU and receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2126 is cleared and the tire pressure warning light goes off.

(a) When checking the ID registration for the 2nd tire set (w/ ID Switching Function):

Operate the steering pad switch assembly and switch the IDs to the 2nd set of tires.

4. REGISTER TRANSMITTER ID (USING AUTOMATIC ID REGISTRATION FUNCTION) (w/ Tire Inflation Pressure Display Function)

NOTICE:

  • If the automatic ID registration operation is canceled while registration is being performed, DTC C2126 is stored in the tire pressure warning ECU and receiver.

When the tire pressure warning ECU and receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2128 is cleared and the tire pressure warning light turns off.
  • If a tire pressure warning valve and transmitter of the same type is carried in the vehicle, registration may not complete.

HINT:

  • When registration is complete, all previously registered IDs are cleared.
  • If DTCs C2176, C2179 and U0129 are stored, registration mode cannot be entered.
  • If the Techstream is being used to display the Data List, registration mode cannot be entered.
  • If the Techstream is used to display the Data List during registration, registration will be canceled.
  • If DTCs C2176, C2179 and U0129 are stored during registration, registration will be canceled.
  • If the power switch is turned off before the vehicle is driven after entering registration mode, registration will be canceled.

  • It is not possible to perform the ID switching function while the system is being checked or during Test Mode.

(1) Install the appropriate tire set to the vehicle.

(2) Turn the power switch on (IG).

(3) Select "Change Wheel" on the multi-information display and press and hold the "OK" switch (steering pad switch assembly) until the tire pressure warning light blinks 3 times.

HINT:

The tire pressure warning light will illuminate for 3 seconds and turn off for 0.5 seconds 3 times.

(b) ID switching function check:

NOTICE:

  • It may take up to a few minutes to update the tire pressure data.
  • When the tire pressure warning ECU and receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, ID switching is complete.
  • After ID switching is performed, DTC C2126 is stored in the tire pressure warning ECU and receiver and the tire pressure warning light blinks for 1 minute and then comes on. When the tire pressure warning ECU and receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2126 is cleared and the tire pressure warning light goes off.

(1) Connect the Techstream to the DLC3.

(2) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

(3) Reduce the tire inflation pressure of each tire 40 kPa (0.4 kgf/cm2, 5.8 psi) or more, and check that the "ID Tire Inflation Pressure" data is updated and that the actual tire inflation pressures are displayed.

(4) After confirming that all of the tire inflation pressure values (except the compact spare tire) have been updated, adjust the tire inflation pressure to the specified value, operate the steering pad switch assembly and perform initialization.
