Theory Of Operation

WARNING: This page is about a different car, the 2020 Chrysler 300 and 2019 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The Memory System is made up of a Memory Seat Module-Driver (MSMD), Memory Switch, Driver Seat Switch, and multiple Seat Motors. If equipped the Memory System can also contain an Adjustable Pedal Motor, Adjustable Pedal Switch, Steering Tilt/Telescope Switch, Steering Telescope Motor and Steering Tilt Motor. The motors each contain a hall-effect position sensor. The hall-effect position sensor provides feedback to the MSMD in relation to the motors position.

The Tilt/Telescope Steering Switch is a 4-way switch that operates the steering column in an up/down tilt direction and in a forward/rearward telescope direction. The MSMD monitors the steering column tilt/telescope position by reading the Tilt Steering Up/Down Position Sense and Telescope Steering Forward/Rearward Position Sense voltages. If the MSMD detects a change in these voltages it commands the corresponding motor to adjust the steering column accordingly.
