CRUISE CONTROL: DYNAMIC LASER CRUISE CONTROL SYSTEM:

FAIL-SAFE CHART

1. AUTO CANCEL FUNCTION (FAIL-SAFE FUNCTION):
HINT: If a system malfunction occurs, the applicable DTCs will appear on the multi-information display.





(a) The CRUISE main indicator light keeps blinking until the main switch is turned off, the master warning light comes on with the warning sound "Pop", and the display shows "CHECK CRUISE SYSTEM". The cruise control operation is suspended until turning the main switch ON again. The auto cancel function deletes the stored vehicle speed and cancels the cruise control operation in the following conditions.
(1) When the vehicle speed signal malfunctions.
(2) When the electronic throttle parts malfunction.
(3) When the stop lamp switch has an open or short circuit.
(4) When the laser sensor malfunctions. (*1)
(5) When the light axis of the laser sensor is off position. (*1)
HINT: *1: Only in the vehicle-to-vehicle distance control mode.





(b) The CRUISE main indicator light blinks, the master warning light comes on with the warning sound "Pop", and the display shows "CRUISE NOT AVAILABLE". The cruise control operation is suspended until the canceling condition is resolved (in the vehicle-to-vehicle distance control mode only). The auto cancel function cancels the cruise control operation in the following condition.
(1) When the wiper (Hi, Lo) operates (including the auto wiper).
(2) When the pattern select switch is in the "SNOW" mode.
(3) When the laser sensor receives strong light, such as sunlight, from the front side.
(4) When the vehicle-to-vehicle distance measurement is extremely unstable because of bad weather.





(c) The auto cancel function cancels the cruise control operation in the following conditions. At this time, the CRUISE main indicator light blinks, the master warning light comes on with the warning sound "Pop" and the display shows "CLEAN RADAR SENSOR". The cruise control operation is suspended until the canceling condition is resolved (in the vehicle-to-vehicle distance control mode only).
(1) When the laser sensor has dirt on it.
HINT: While the dynamic laser cruise control is operated, the hybrid vehicle control ECU outputs a malfunction code for 0.15 sec. or more when it detects dirt.

2. Constant speed control mode and vehicle-to-vehicle distance control mode:
If the following conditions are detected while the dynamic laser cruise control system is in operation, the system clears the stored vehicle speed and cancels the dynamic laser cruise control operation.
HINT: In the vehicle-to-vehicle distance control mode, the stored vehicle speed in the hybrid vehicle control ECU is maintained.





HINT:
*1: Constant speed control mode
*2: Vehicle-to-vehicle distance control mode
