REGISTRATION

PROCEDURE

1. Clarification OF CODE REGISTRATION

HINT:

The ID codes are the same as recognition codes for the wireless transmitter and the engine immobiliser function. Registering an ID code enables the smart fundamental organisation, the wireless door lock control function and the engine immobiliser function to exist operated.
Code registration is necessary when the certification ECU (smart key ECU associates), steering lock ECU (steering lock actuator assembly), or primal is replaced with a new one.

(a) Vehicles with the smart central organisation practice not have a cardinal slot. Therefore, agree the primal shut to the engine switch to register the central, as shown in the analogy.

ii. Cardinal REGISTRATION PROCEDURES WHEN ADDING OR REPLACING KEY OR WHEN Fundamental IS LOST

HINT:

The following procedures require the use of the Techstream:
- - New primal ID registration
- - Additional cardinal ID registration
- - Key ID erasure
- -All fundamental ID erasure
A maximum of 7 keys can be registered.
