Registration
REGISTRATION1. READ TRANSMITTER ID
(a) When replacing the tire pressure warning ECU and receiver, read the ID stored in the old ECU using the intelligent tester.
(b) When replacing the tire pressure warning valve and transmitter, read the ID written on the tire pressure warning valve and transmitter.
2. REGISTER TRANSMITTER ID
NOTICE: It is necessary to register the transmitter ID in the tire pressure warning ECU and receiver when replacing the tire pressure warning valve and transmitter and/or tire pressure warning ECU and receiver.
(a) Set the air pressure of 4 wheels, to the specified value (Procedure "A").
(b) Connect the intelligent tester to the DLC3 (Procedure "B").
(c) Turn the engine switch on (IG) (Procedure "C").
(d) Read and write down the ID (ID1 to ID4) by using the DATA LIST (Procedure "D").
(e) Select the REGIST TIRE following the intelligent tester screen (UTILITY - REGIST TIRE) (Procedure "E").
NOTICE:
^ The registered IDs in the memories will be deleted when performing the registration.
^ If the procedures of the registration are not completed within 5 minutes, the mode returns to normal operation mode.
^ If the system is in the initialization mode, it is unable to perform registration. Therefore, restart the registration after terminating the initialization or confirming that the initialization has been completed.
(f) Select the registration mode "MAIN".
HINT: Select "2nd" when registering in 2nd.
(g) Input the ID (ID1 to ID4) using the intelligent tester and transmit it to the tire pressure warning ECU and receiver (Procedure "F").
(h) Set the ID transmission condition to "ID Registration is complete" (Procedure "G").
(i) Disconnect the intelligent tester with the engine switch off.
3. CONFIRMATION OF TRANSMITTER ID REGISTRATION
(a) Set the air pressure of 4 wheels, to the specified value.
*1: Only for front tire
*2: Only for rear tire
(b) Connect the intelligent tester to the DLC3.
(c) Turn the engine switch on (IG).
(d) Select "SIGNAL CHECK" on the intelligent tester.
(e) Perform forced transmission of the transmitter IDs of 4 wheels.
(1) Remove the valve core, rapidly reducing the pressure (above 40 kPa (0.4 kgf/cm2, 5.8 psi)/ 30 sec.).
HINT: The transmitter ID can be transmitted by rapidly reducing the tire air pressure.
(2) Perform the steps mentioned above to all tires.
(f) Check that test mode DTCs C2181/81, C2182/82, C2183/83, C2184/84 are all cleared.
HINT:
^ The transmitter ID registration is completed when the test mode DTCs are cleared.
^ If the DTCs have not been cleared, reset the tire pressure to the specified value and rotate the tire 90 to 270 degrees. Then perform forced transmission of the transmitter IDs of all wheels. If the DTCs are still output, register the transmitter IDs.
(g) Set the pressure of 4 wheels to the specified value.
4. PROCEDURE FOR DETERMINING THE INSTALLED WHEEL'S TRANSMITTER ID STATUS ("MAIN" OR "2ND")
(a) Turn the engine switch on (IG).
(b) Set the tire select switch to the "MAIN" position.
(c) Set the tire pressure of 4 wheels to the specified value. (Procedure "C")
*1: Only for front tire
*2: Only for rear tire
(d) Remove the valve core, rapidly reducing the pressure (above 40 kPa (0.4 kgf/cm2), 5.8 psi/30 sec.). (Procedure "D")
(e) Check the following items. If both of them are true, the transmitter ID of the currently installed wheel is registered in the "MAIN". (Procedure "E")
^ Tire pressure warning light comes on.
^ Each tire pressure data displayed on the intelligent tester screen has been changed.
(f) If either of the conditions is not true, switch the tire select switch to "2nd" and perform steps Procedure "C" to Procedure "E". If both are true, the transmitter ID of the currently installed wheel is registered in "2nd".
