Fail-Safe Function

FAIL-SAFE FUNCTION
In addition to the normal and automatic canceling functions as described in paragraphs 1 and 2 below, the cruise control system has a fail-safe canceling function as described in paragraph 3.


1. NORMAL CANCELING FUNCTION
If any of the following action is performed, the system is canceled.

1. Brake pedal is depressed.
2. Clutch pedal is depressed. (MT model)
3. Selector lever is placed in the "P" or "N" position. (AT model)
4. Cruise control main switch is turned off.


2. AUTOMATIC CANCELING FUNCTION
If any of the following states occurs, the system is automatically canceled.

1. Vehicle speed lowers below the minimum system operation speed.
2. Vehicle speed lowers 15 ± 3 km/h than the set speed.


3. FAIL-SAFE CANCELING FUNCTION
If any of the following states occurs, the system is canceled.

1. Faults in cruise control module
1. The condition of the actuator drive circuit does not coincide with the output condition of CPU.
2. Fault occurs in the command switch input circuit.
3. Set speed (CPU RAM value) is abnormal.
4. Fault occurs in the cancel latch circuit.

2. Abnormality in vehicle speed inputs
If the following state occurs, the system is temporarily canceled.

1. Vehicle speed becomes 10 km/h higher than the set speed.
In this case, the system resumes operation when the vehicle speed becomes lower than the set speed + 7 km/h.
