INITIALIZE DISTANCE CONTROL ECU ASSEMBLY
NOTE: After replacing the distance control ECU, it is necessary to initialize the distance control ECU so that the ECU can recognize the specification of the vehicle.
1. Be sure to perform the following procedures after replacing the distance control ECU.
  1. Turn the engine switch on (IG).
  2. Turn the cruise control main switch on.
  3. With the brake 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 ).
PERFORM INITIALIZATION
NOTE: Some systems need initialization when disconnecting the cable from the negative battery terminal. (See INITIALIZATION )
