12. REGISTRATION RELATED TO GARAGE DOOR OPENER

(a) REGISTER TRANSMITTER CODE

HINT
* The vehicle garage door opener records transmitter codes for systems such as garage doors, gates, entry gates, door locks, home lighting systems, security systems or other transmitter code based systems.
* The garage door opener is built into the map light assembly. If replacing the map light assembly transmitter, codes for any systems previously registered in the garage door opener must be reregistered.
(1) Register systems in the garage door opener registration mode.

CAUTION:
Do not perform transmitter code registration for a system if people or objects are near the system. When registering transmitter codes for a system, injury or damage can occur because the system may open, close, unlock or otherwise operate.

NOTICE:
* Before transmitter code registration, confirm that all the electrical systems (headlight, blower motor, rear defogger, etc.) are turned off and that no key is in the vehicle.
* The garage door opener cannot be used with systems that: 1) were manufactured before April 1, 1982, or 2) do not meet Federal Standards (for example, garage doors without a jam protection function).
HINT
* 3 transmitter codes can be registered with the garage door opener, one transmitter code for each of the 3 garage door opener switches.
* Disconnecting the battery will not clear the transmitter codes registered with the garage door opener.
1 Select a garage door opener switch for transmitter code registration.

2 Press and hold the selected switch. The garage door opener will enter registration mode after a brief pause.









HINT
After entering registration mode, the LED flashes at a frequency of 1 Hz.

3 After the garage door opener has entered registration mode, continue holding the selected garage door opener switch and bring the original transmitter of the system to be registered within 1 inch of the garage door opener switches. Then, without releasing the selected garage door opener switch, press and hold the original transmitter switch.









4 If the transmitter code registration was successful, the LED of the garage door opener flashes at a frequency of 5.6 Hz, and the registration completes. If no malfunction occurs, release both the garage door opener switch and the original transmitter switch.





(2) Overwrite previously registered systems in the garage door opener registration mode.

1 Select a garage door opener switch that will be overwritten with a new transmitter code.

2 Press and hold the selected switch. After approximately 20 seconds, the garage door opener will enter registration mode.









HINT
Before entering registration mode, the LED is on. After entering registration mode, the LED flashes at a frequency of 1 Hz.

3 After the garage door opener has entered registration mode, continue holding the selected garage door opener switch and bring the original transmitter of the system to be registered within 1 inch of the garage door opener switches. Then, without releasing the selected garage door opener switch, press and hold the original transmitter switch.









4 If the transmitter code registration was successful, the LED of the garage door opener flashes at a frequency of 5.6 Hz, and the overwriting completes. If no malfunction occurs, release both the garage door opener switch and the original transmitter switch.

HINT
* If transmitter code registration fails: 1) the original transmitter battery may be low or need to be replaced, or 2) the system you are trying to register may not be compatible with the garage door opener.
* The signals of some transmitters stop after 1 to 2 seconds. For these types of transmitters: 1) press and hold one of the garage door opener switches, and 2) press and release (cycle) the transmitter switch every 2 seconds. Check if the transmitter code was successfully registered.
* After entering the garage door opener registration mode, transmitter code registration must be completed within 55 seconds. If 55 seconds elapse, the garage door opener will enter low power mode (refer to the "low power mode" below).





(3) Clear transmitter codes in the garage door opener clear mode.

HINT
All 3 registered transmitter codes will be cleared. No option exists for only erasing one transmitter code.

1 Press and hold the left and right switches at both ends of the garage door opener for 10 seconds. The LED will flash at a frequency of 5.6 Hz, and clearing is completed. Releasing the switches will end clear mode.









HINT
* If the switches are released within 10 seconds after the transmitter codes have been cleared, the garage door opener will enter registration mode.
* If the switches are held for 10 seconds or more after the transmitter codes have been cleared, default codes will be set to the switches of the garage door opener. Using these default codes, operation of the garage door opener can be checked using a tester.





(4) Low power mode:

1 If the garage door opener switch is held for 75 seconds or more, the garage door opener will enter low power mode to economize on power consumption. When the garage door opener has entered low power mode, the LED turns off.

13. DCM ACTIVATION

This function should be used to activate the DCM (Telematics Transceiver) after a new DCM (Telematics Transceiver) has been installed. During the DCM Activation process, Techstream automatically provides the telematics service provider with the new DCM (Telematics Transceiver) information and deletes the old DCM (Telematics Transceiver) information associated with the vehicle. The DCM (Telematics Transceiver) that was replaced should be returned to the parts department.

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Choose "Telematics" from the System Selection Menu, and then click "Utility".

(e) Click "DCM Service" on the Utility Selection Menu.

(f) Choose "Activate DCM" and then click "Next" on the DCM Service Utility.





(g) Follow the instructions on the Techstream.

HINT
* If PRL is not latest version, utility will report that a PRL update must be performed before DCM Activation can be completed.
* If a fault occurs during DCM Activation, a specific fault message will be displayed with procedure guidelines.
* The manual (SOS) switch green indicator will turn on if activation is successful.






HINT
If the one these fault code is present, follow the procedure indicated in the following list.

* Fault 20: Try DCM Activation again.
* Fault 61: Replace the DCM (Telematics Transceiver) with a new service part and perform DCM Activation.
* Fault 62*: Verify VIN is correct in ECM. Run Vehicle Inquiry and verify VIN.
* Fault 63: Replace the DCM (Telematics Transceiver) with a new service part and perform DCM Activation.
* Fault 64*: Verify that the DCM (Telematics Transceiver) is a new service part.
* Fault 66*: Replace the DCM (Telematics Transceiver) with a new service part and perform DCM Activation.
* Fault 67: Try DCM Activation again. If the fault occurs again, wait and try again later.
* *: As the fault could also be caused by a problem in communicating with the call center, before replacing the DCM, check with the call center to determine it there is a database or communication problem.
* (Call Center number for LEXUS vehicle: 800-255-3987)
(h) Push the manual (SOS) switch to call an operator and confirm that the DCM (Telematics Transceiver) is activated.
