Registration
REGISTRATION1. DESCRIPTION OF CODE REGISTRATION
It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing the tire pressure warning valve and transmitter and/or tire pressure warning ECU.
(a) Before registration
(1) In case of tire pressure warning ECU replacement.
^ Read the registered transmitter IDs that are stored in the old ECU using the intelligent tester and note them down.
^ If reading stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning antenna and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valves and transmitters.
(2) In case of tire pressure warning valve and transmitter replacement.
^ When replacing the tire pressure warning valves and transmitters, note down the IDs written on the tire pressure warning valves and transmitters.
2. REGISTER TRANSMITTER ID
(a) Connect the intelligent tester to DLC3 (Procedure "A").
(b) Turn the engine switch on (IG) (Procedure "B").
(c) Select the REGIST TIRE following the intelligent tester screen (UTILITY - REGIST TIRE) (Procedure "C").
(d) Select the registration mode "MAIN" (Procedure "D").
HINT:
^ Check that tire pressure warning select switch is "MAIN".
^ When registering second set, select the registration mode "2nd" after changing tire pressure warning select switch to "2nd".
(e) Input the IDs (ID1 to ID4 or ID5) using the intelligent tester and transmit them to the tire pressure warning ECU (Procedure "E").
(f) Set the ID transmission condition to "ID Registration is complete" (Procedure "F").
HINT:
^ The previously registered IDs will be deleted from the memory when the registration is completed.
^ If the procedures "C" to "E" are not completed within 5 min. the mode will return to the normal operation mode.
^ When the system is in initialization mode after the tire pressure warning reset switch has been operated, the registration is disabled until the initialization process is canceled or completed.
Registration Procedure:
3. CONFIRMATION OF TRANSMITTER ID REGISTRATION
(a) Connect the intelligent tester to DLC3 (engine switch is off).
(b) Turn the engine switch on (IG).
(c) Select "TIREPRESS" by following the prompts displayed on the intelligent tester.
(d) Confirm that the data of tire pressure of all tires (including the full-size spare tire) are displayed on the intelligent tester screen.
NOTICE:
^ It may take up to 1 minute or more to update the tire pressure data.
^ If the IDs have not been registered, some of DTC C2171/71 is set in the tire pressure warning ECU after 51 minutes or more.
