Position Sensors

There are also position sensors that are potentiometers which attached to each motor's transmission cable. When the cable rotates, the resistance of the potentiometer varies and the feedback voltage is monitored by the MSM to determine the motor's position. The sensor feedback voltage varies from 0.5 volts to 4.5 volts. When a memory set command is received, the MSM records the motor positions by storing the feedback voltage of their respective position sensors. When a memory recall command is received, the MSM moves the motors until all the position sensor feedback voltages equals the feedback voltages stored in memory. For easy exit functions, only seat position sensor feedback voltages are recorded and only the seat motor run. The lumbar support is not involved in the easy exit function.
