INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION - (Continued)

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.

14. REGISTRATION RELATED TO ENTRY AND START

(a) DESCRIPTION OF CODE REGISTRATION

HINT
* The engine immobiliser function ID code is the same as the recognition code for the smart key system and wireless transmitter. Registering an ID code enables the smart key system, wireless door lock control function and engine immobiliser function to be operated.
* Code registration is needed when the certification ECU (smart key ECU assembly), ID code box (immobiliser code ECU), steering lock ECU, ECM or key is replaced with a new one.

* This vehicle does not have a key slot. Therefore, touch the logo of the key to the engine switch to register the key, as shown in the illustration.
(b) KEY REGISTRATION PROCEDURES WHEN ADDING OR REPLACING KEY OR WHEN KEY IS LOST

HINT
* The following procedures require the use of the Techstream:
* - New key ID registration
* - Additional key ID registration
* - Key ID erasure
* A maximum of 7 keys can be registered.

(c) PART REPLACEMENT AND KEY REGISTRATION PROCEDURES

(1) If a malfunctioning ECU is discovered through troubleshooting of the smart key system, use the ECU replacement and key registration procedures in the table below.

HINT
* The following procedures require the use of the Techstream:
* - New key ID registration
* - Additional key ID registration
* - Key ID erasure
* - ECU code registration
* A maximum of 7 keys can be registered.

HINT
*: Repeat this process for each key which is to be registered to the vehicle. Finish the procedure for each key within 30 seconds. If the procedure for any of the keys has not been finished within the specified time, perform the registration from process 1 again. Make sure that only 1 key is in the cabin during registration. If 2 or more keys are in the cabin simultaneously, the electric waves will interfere with each other, preventing normal registration.

(2) PROCEDURE "B"

New key ID registration (when replacing certification ECU (smart key ECU assembly)):

HINT
* *1: Repeat this process for each key registered to the vehicle. Finish the procedure for each key within 30 seconds. If the procedure for any of the keys has not been finished within the specified time, perform the registration from process 1 again. When performing the key confirmation procedure for a key, the security indicator light comes on and remains on until all the keys are confirmed.
* *2: Repeat this process for each key which is to be registered to the vehicle. Finish the procedure for each key within 30 seconds. If the procedure for any of the keys has not been finished within the specified time, perform the registration from process 1 again. Make sure that only 1 key is in the cabin during registration. If 2 or more keys are in the cabin simultaneously, the electric waves will interfere with each other, preventing normal registration.
(3) PROCEDURE "C"

Additional key ID registration:

HINT
* *1: Perform this process for one of the keys registered to the vehicle. Finish the procedure within 30 seconds. If the procedure has not been finished within the specified time, perform the registration from process 1 again.
* *2: Repeat this process for each key which is to be registered to the vehicle. Finish the procedure for each key within 30 seconds. If the procedure for any of the keys has not been finished within the specified time, perform the registration from process 1 again. Make sure that only 1 key is in the cabin during registration. If 2 or more keys are in the cabin simultaneously, the electric waves will interfere with each other, preventing normal registration.
