DESCRIPTION
Signals are input into the position control ECU and switch assembly. The built-in ECU manages the signals received from the position control ECU and switch assembly, and operates each motor. If the position control ECU and switch assembly receives more than 2 motor operation signals, the motor is stopped. Manual operation is restarted after the position control ECU and switch assembly receives 1 signal only.
