REGISTRATION

CAUTION / NOTICE / HINT

HINT:

Register a new recognition code when replacing the door control transmitter module set sub-assembly or the door control receiver.
Add mode is used to retain the already registered codes while registering a new recognition code. This mode is used when adding a door control transmitter module set sub-assembly.
Rewrite mode is used to clear all the previously registered codes and register only new recognition codes. This mode is used when exchanging the door control transmitter module set sub-assembly or the door control receiver with new one.
Confirmation mode is used to confirm how many recognition codes have already been registered before additional registration of a recognition code.
Prohibition mode is used to clear all the registered codes and cancel the wireless door lock function. Use this mode when the door control transmitter module set sub-assembly is lost.
All of the steps in the following registration procedure must be performed in sequential order continuously.

PROCEDURE

1. REGISTRATION OF RECOGNITION CODE (USING TECHSTREAM)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter the following menus: Body Electrical / Main Body / Utility / Wireless Code Registration.

(e) Select either add or rewrite mode according to the Techstream display.

(f) The number of registered codes is indicated.

(g) Registration of the door control transmitter module set sub-assembly.

(1) If either add mode or rewrite mode has been selected, press the LOCK and UNLOCK switches on the door control transmitter module set sub-assembly simultaneously.

(2) Within 3 seconds of releasing the LOCK and UNLOCK switches, press either of the switches on the door control transmitter module set sub-assembly.

NOTICE:

Do not press the LOCK and UNLOCK switches simultaneously for more than 1.5 seconds.
Perform this operation within 1 meter of the driver seat to register the door control transmitter module set sub-assembly.
Do not push other door control transmitter module set sub-assembly switches during the door control transmitter module set sub-assembly registration process.

(3) The main body ECU (multiplex network body ECU) automatically performs the power door LOCK-UNLOCK operation once in order to indicate whether registration has been completed correctly or not.

(4) If continuing registration, the next recognition code must be registered in the door control transmitter module set sub-assembly within 30 seconds.

HINT:

Up to 6 recognition codes can be registered.

(h) Completing the registration mode.

(1) Registration mode will end when any of the following occurs:

30 seconds or more have elapsed after a code is registered.
