10. INITIALIZE HYBRID VEHICLE CONTROL ECU
NOTE: After replacing the hybrid vehicle control ECU on vehicles with a dynamic laser cruise control system, it is necessary to initialize the hybrid vehicle control ECU so that the ECU can recognize the dynamic laser cruise control system.

(a) Be sure to perform the following procedures after replacing the ECU.
(1) Turn the ignition switch to the on position.
(2) Turn the cruise 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 Adjustments.

11. PERFORM INITIALIZATION
Some systems need initialization when disconnecting the cable from the negative battery terminal. Repair Instruction - Initialization
