FRONT POWER SEAT CONTROL SYSTEM(w/ Memory) One or more Power Seat Motors do not Operate

DESCRIPTION

Signals are input into the front power seat switch LH or front power seat switch RH. The built-in ECU manages the signals received from the front power seat switch LH or front power seat switch RH, and operates each motor. If the front power seat switch LH or front power seat switch RH receives more than 2 motor operation signals, the motor is stopped. Manual operation is restarted after the front power seat switch LH or front power seat switch RH receives 1 signal only.
