REGISTER IMMOBILISER COMMUNICATION ID
NOTE: If the ECM is replaced, register the ECM communication ID for the immobiliser system (refer to the Service Bulletin for registration).
PERFORM INITIALIZATION
NOTE: After replacing the ECM on vehicles with a dynamic laser cruise control system, it is necessary to initialize the ECM so that the ECM can recognize the dynamic laser cruise control system.
1. Be sure to perform the following procedure after replacing the ECM.
  1. Turn the ignition switch on (IG).
  2. Turn the cruise control main switch on.
  3. With the Drake pedal depressed, push the cruise control main switch to RES/ACC 3 times within 3 seconds. Check that the buzzer sounds at this time.
    NOTE: Do not turn the headlight dimmer switch on at this time because the optical axis automatic adjustment mode has already started, which may lead to an incorrect optical axis setting. If the headlight dimmer switch is turned on by mistake, readjust the optical axis (See ADJUSTMENT ).
