7. PERFORM SYSTEM INITIALIZE
Some systems need initialization when disconnecting the battery terminal.
8. INITIALIZE ECM
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.
a. Be sure to perform the following procedures after replacing the ECM.
1. Turn the ignition switch on (IG).
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.
