1. FAIL-SAFE FUNCTION
a. The ECU stops operating the multiplex tilt and telescopic steering column when a changed signal is not input to the ECU while the unit is in operation.

HINT: Each motor has a built in position sensor.

b. The ECU temporarily stops operating the tilt or telescopic steering column when the power supply to the ECU decreases to approximately 8 ± 1 V or less while the unit is in operation.

HINT: When the power supply returns to normal within 10 seconds after the signal to operate the tilt or telescopic steering column is input to the ECU, the ECU starts operating the unit. When the power supply returns to normal after 10 seconds or more elapses, the ECU starts operating it the next time the tilt or telescopic steering column operational signal input to the ECU.





c. If the communication of ECU related to this system is interrupted, the ECU effects the controls listed.
