PRE-CHECK1. DYNAMIC LASER CRUISE CONTROL SYSTEM DESCRIPTION
a. This system maintains the vehicle running at the fixed speed that the driver has set, as long as there are no vehicles ahead in the same lane. Then, the system maintains the vehicle distance that has been set by the driver.
If the system detects a front vehicle moving slower speed than one's own vehicle while the driver is driving at a fixed speed, it closes the throttle valve to decelerate. If additional deceleration is necessary, it shifts the gears down to decelerate. If further deceleration is required, the system controls the brake actuator in order to apply the brakes. Thereafter, if there are no front vehicles within the set vehicle-to-vehicle distance because either the vehicle in front or the driver has changed lanes, the system accelerates slowly to reach the set vehicle speed and resumes driving at the fixed speed.
b. (fixed speed) cruise control mode that effects control only to maintain a fixed cruising speed. The vehicle-to-vehicle distance control mode that effects cruising at a fixed speed function, deceleration cruising function, follow-up cruising function, and acceleration cruising function. These two modes can be switched by operating the cruise control main switch.
c. A steering pad switch (Distance control switch) for setting the distance to the front vehicle is provided on the steering wheel pad.
With this switch, the vehicle distance can be set in the following three stages: LONG, MIDDLE, and SHORT.
2. LASER BEAM AXIS ADJUSTMENT
Use the hand-held tester to adjust to the optical axis for the optical axis adjusting operation).
HINT: While adjusting the optical axis of the laser radar sensor, the CRUISE main indicator light illuminates and FC is displayed on the multi-information display.
3. DIAGNOSIS FUNCTION
The diagnosis function makes the master warning light and the multi-information display to comes on, and CRUISE main indicator light blinks as shown in the illustration, when a malfunction occurs in the dynamic laser cruise control system, and store the diagnosed result in the ECM.
NOTE:
- The master warning light goes off if the system returns to normal condition.
- Since the stored data in the ECM is erased by disconnecting the EFI fuse and the battery terminal, do not disconnect them until finishing the inspection.
