Title: TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: REGISTRATION; 2020 - 2024 MY Camry [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:

  • When 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, place the tires and wheels of the 2nd tire set and main tire set close to the vehicle (less than 10 m (32.8 ft.) away from the vehicle).

    HINT:

    When registering an ID on the 2nd tire set, a tire and wheel which have an ID from the main tire set are necessary to also perform ID certification for the main tire set. If ID certification is not performed on the main tire set, DTC C2126 is stored by the tire pressure warning ECU and receiver.

  • When using the 2nd tire set or switching from the 2nd tire set to the main tire set after registration for the 2nd tire set is completed, switch to the appropriate set of IDs after installing the tires and wheels.

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:

    In order to perform ID registration for the 2nd set of tires, select "2nd Set" on the display screen.

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