Toyota Camry (XV70): Registration

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
*1	Tire Pressure Warning Valve and Transmitter	-	-
*a	Transmitter ID (7-digit Number)	-	-

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.

Click here

(b) Turn the ignition switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration/Tire Number Registration.

Chassis > Tire Pressure Monitor > Utility

Tester Display
ID Registration/Tire Number Registration

(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

• 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.
• If the automatic ID registration is started while DTC C2126 is stored, DTC C2126 and C2128 are stored in the tire pressure warning ECU and receiver.
• During registration, DTC C2128 is stored by the tire pressure warning ECU and receiver and the tire pressure warning light blinks for 1 minute 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 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 ignition switch is turned off before the vehicle is driven after entering registration mode, registration will be canceled.

(a) Adjust the tire pressure in all tires to the specified pressure.

(b) Turn the ignition switch off and stop the vehicle for 15 minutes or more.
