Abnormalities In Electric Circuits

The cruise control system is deactivated and the set speed is also canceled if any of the following abnormalities occurs in the system's electric circuits.

The system deactivation function is retained until the ignition switch or the main switch is turned OFF.

1. The stepping motor terminal is grounded or disconnected; or the stepping motor drive circuit is broken due to a short-circuit.
2. The stepping motor clutch drive circuit is shorted.
3. Vehicle speed variation in a 350 ms period exceeds +/-10 km/h (+/-16 MPH).
4. Fusion has occurred in an internal relay and is detected while the vehicle is running with the cruise control deactivated.
5. The cruise control module becomes inoperative or its operation is faulty.
6. There is discrepancy between the values stored in the two RAMs of the control module.
7. An abnormality is detected as a result of the self-diagnosis performed after turning ON of the ignition switch.
